Tachycardia : Causes-Symptoms-Diagnosis-Treatment

 What is Tachycardia?

Tachycardia is the term for a vital sign that’s quicker than traditional, over a hundred beats per minute. arrhythmia will begin in your higher or lower chambers of your heart and may vary from gentle to severe. Treatments embody medicines and procedures like ablation and implantable internal organ electronic device (ICD) placement.

When you have arrhythmia, your heart beats quicker than it ought to for many seconds to many hours. Normally, your vital sign is sixty to a hundred beats per minute once you’re not active. once your heart beats over a hundred times a moment, that’s arrhythmia. As a result of your heart beating too often, it doesn’t have the time it must fill with blood between beats. This could be dangerous if your heart can’t provide all of your cells with the blood and gas they have.

What is Tachycardia?

Your heart ordinarily responds to electrical signals from your heart’s sinoatrial (SA) node. These signals management however usually your heart beats. Once you’ve had a scare or square measure terribly emotional or anxious, your heart might send signals a lot of often for a brief time. This is often referred to as sinus arrhythmia and goes away after you relax. different styles of arrhythmia will come often and may be a lot of serious.

These styles of tachycardias begin within the atrium or higher part of your heart, wherever there’s a drag with electrical signals.

Medical terms

  • Tachycardia (tak-ih-KAHR-dee-uh) is the medical term for a pulse over a hundred beats a second. Many sorts of irregular heart rhythms (arrhythmias) will cause cardiac arrhythmia.

  • A fast pulse is not a priority. As an example, the center rate generally rises throughout exercise or as a response to worry.

  • Tachycardia might not cause any symptoms or complications. However, if left untreated, some types of cardiac arrhythmia will cause serious health issues, together with cardiomyopathy, stroke or fulminant internal organ death.

  • Treatment for cardiac arrhythmia might embrace specific maneuvers, medication, cardioversion or surgery to regulate a speedy heartbeat.

Tachycardia is a heart condition that causes the heart to beat too quickly Tachycardia causes symptoms like chest pain dizziness difficulty breathing and fainting Though tachycardia can be life-threatening in the short term it rarely leads to serious long-term problems if detected early and treated promptly

A fast heart rate or tachycardia is when your heart beats faster than normal The average resting rate for an adult is 60 to 80 beats per minute (bpm) In general if you have a resting heart rate of more than 100 bpm this is considered tachycardia It's normal for children and teens to have a higher heart rate that can range between 100 and 120 bpm or even higher under certain conditions Tachycardia in children should be evaluated by a healthcare provider if it persists over several days or causes other symptoms such as fainting or dizziness

Types Tachycardia

Their square measures many alternative forms of arrhythmia. Sinus arrhythmia refers to a typical increase within the pulse rate usually caused by exercise or stress.

Other forms of arrhythmia square measure are classified consistent with a part of the center accountable for the quick pulse rate and also the cause. Common forms of arrhythmia caused by irregular heart rhythms (arrhythmias) include:

  • Atrial fibrillation (A-fib). This is the foremost common sort of arrhythmia. Chaotic, irregular electrical signals within the higher chambers of the guts (atria) cause a quick heartbeat. A-fib could also be temporary, however some episodes will not finish unless treated.

  • Atrial flutter. Atrial flutter is analogous to A-fib, however heartbeats square measure additional organized. Episodes of chamber flutter could get away themselves or could need treatment. folks that have chamber flutter additionally usually have fibrillation at different times.

  • Ventricular tachycardia. This type of heart disease starts within the lower heart chambers (ventricles). The speedy rate does not permit the ventricles to fill and squeeze (contract) to pump enough blood to the body. Cavity arrhythmia episodes are also temporary and last solely one or two seconds while not inflicting damage. However, episodes lasting over a couple of seconds are often critical.

  • Supraventricular tachycardia (SVT). Supraventricular arrhythmia may be a broad term that has arrhythmias that begin higher than the ventricles. Supraventricular arrhythmia causes episodes of a pounding heartbeat (palpitations) that begin and finish short.

  • Ventricular fibrillation. Rapid, chaotic electrical signals cause the ventricles to quiver rather than acquiring during a coordinated means. This significant issue will result in death if the guts rhythm is not fixed up among minutes. The majority of UN agencies have fibrillation, have Associate in Nursing underlying cardiomyopathy or have tough serious trauma, like being affected by lightning.

Symptoms Tachycardia

When the center beats too quickly, it's going to not pump enough blood to the remainder of the body. As a result, the organs and tissues might not get enough gas.

In general, cardiac arrhythmia could cause the subsequent signs and symptoms:

  • Sensation of a racing, pounding heartbeat or flopping in the chest (palpitations)

  • Chest pain

  • Fainting (syncope)

  • Lightheadedness

  • Rapid pulse rate

  • Shortness of breath

Some people with tachycardia have no symptoms. The condition may be discovered when a physical exam or heart tests are done for another reason.

When to see a doctor

A number of things will cause a speedy vital sign (tachycardia). If you're feeling like your heart is thrashing too quickly, build a rendezvous to envision a health care supplier.

Seek immediate medical assistance if you've got shortness of breath, weakness, dizziness, lightheadedness, fainting or close to fainting, and hurting or discomfort.

A type of cardiac arrhythmia referred to as fibrillation will cause force per unit area to drop dramatically. Collapse will occur inside seconds. presently the affected person's respiratory and pulse can stop. If this happens, do the following:

  • Call 911 or the emergency number in your area.

  • If you or someone nearby is well trained in CPR, start CPR. CPR can help maintain blood flow to the organs until an electrical shock (defibrillation) can be given.

  • If you're not trained in CPR or worried about giving rescue breaths, then provide hands-only CPR. Push hard and fast on the center of the chest at a rate of 100 to 120 compressions a minute until paramedics arrive. You don't need to do rescue breathing.

  • If an automated external defibrillator (AED) is available nearby, have someone get the device for you, and so follow the directions. associate degree AED may be a moveable medical aid device which will deliver a shock to reset the guts rhythm. No coaching is needed to use the device. The AED can tell you what to try to do. It's programmed to administer a shock only if acceptable.

Causes Tachycardia

Tachycardia is AN enhanced vital sign for any reason. It is a usual rise in vital signs caused by exercise or a stress response (sinus tachycardia). Sinus cardiac arrhythmia is taken into account as a signal, not an illness.

Tachycardia may be caused by AN irregular rhythm (arrhythmia).

Things which will cause cardiac arrhythmia include:

  • Fever

  • Heavy alcohol use or alcohol withdrawal

  • High levels of caffeine

  • High or low blood pressure

  • Imbalance of substances in the blood called electrolytes — such as potassium, sodium, calcium and magnesium

  • Medication side effects

  • Overactive thyroid (hyperthyroidism)

  • Reduced volume of red blood cells (anemia), often caused by bleeding

  • Smoking

  • Use of illegal drugs, including stimulants such as cocaine or methamphetamine

Sometimes the exact cause of tachycardia can't be determined.

How does the heart beat?

To understand the reason for arrhythmia, it should be useful to grasp however the guts generally works.

The heart is created of 4 chambers — 2 higher chambers (atria) and 2 lower chambers (ventricles).

The heart's rhythm is controlled by a natural pacemaker (the sinus node) within the right higher chamber (atrium). The sinus node sends electrical signals that commonly begin every heartbeat. These electrical signals move across the atria, inflicting the guts muscles to squeeze (contract) and pump blood into the ventricles.

Next, the signals gain a cluster of cells referred to as the Av node, wherever they block. This slight delay permits the ventricles to fill with blood. Once the electrical signals reach the ventricles, the chambers contract and pump blood to the lungs or to the remainder of the body.

In a typical heart, this heart communication method sometimes goes swimmingly, leading to a resting pulse of sixty to a hundred beats a moment.

Risk factors Tachycardia

In general, growing older or having a case history of bound regular recurrence issues (arrhythmias) might increase the chance of arrhythmias that normally cause cardiac arrhythmia.

Lifestyle changes or medical treatment for connected heart or different health conditions might decrease the chance of cardiac arrhythmia.

Complications Tachycardia

Complications of tachycardia depend on:

  • The type of tachycardia

  • How fast the heart is beating

  • How long the rapid heart rate lasts

  • If there are other heart conditions

Some folks with cardiac arrhythmia have AN exaggerated risk of developing a blood that might cause a stroke (risk is highest with chamber fibrillation) or heart failure. Your health care supplier could order a blood-thinning medication to assist lower your risk.

Other potential complications of cardiac arrhythmia include:

  • Frequent fainting or unconsciousness

  • Inability of the heart to pump enough blood (heart failure)

  • Sudden death, usually only associated with ventricular tachycardia or ventricular fibrillation

How can I reduce tachycardia immediately?

  • If you feel tachycardia coming on your first reaction may be to pull over and rest This is a good start but there are other things you can do to help reduce your heart rate First of all make sure you're in a place where it's safe for you to slow down and stop for a few minutes Unbuckle your seat belt so that if you need to jump out and throw up or pass out you'll have the freedom to do so in the safest manner possible If driving with someone else present who has knowledge of CPR or any medical training (nurse or EMT.

  • Tachycardia is a serious heart condition and should be treated by a health care provider However there are things you can do to help reduce the symptoms and discomfort associated with this condition.

How serious is tachycardia?

Tachycardia or a rapid heartbeat can be caused by factors such as anxiety about an upcoming test exercise caffeine and more The serious form of this condition is called ventricular tachycardia (VT) and results from electrical signals in the heart becoming out of sync It may cause chest pain and shortness of breath Seek medical attention if you experience these symptoms.

Tachycardia is a heart problem that results in abnormally fast heart beat Although the condition occurs naturally during some physical activities such as running or climbing stairs it is usually caused by an underlying health condition Visit your doctor to find out if you have tachycardia and what treatment options are available for you.

At what heart rate should you go to the hospital?

When you arrive at the emergency room an EKG will be performed Then the doctor will order a cardiac enzyme test to look for evidence of heart attack damage in your heart muscle tissue This test is especially important if you have risk factors for coronary artery disease and a history of heart valve problems.

Is 110 pulse rate normal?

According to the American Heart Association a healthy young adult's heart rate can range from 60 to 100 beats per minute (bpm) depending on level of exercise and whether you're male or female When you're at complete rest -- sitting still eyes closed and any activity that doesn't require exercising muscles - your heart rate should fall within the lowest end of this range As soon as you begin physical activity beyond complete rest -- engaging in even mild exercises such as walking up stairs or taking a stroll - your heart rate rises to somewhere between 60 and 100 bpm This is in the normal range for your pulse during exercise.

Prevention Tachycardia

The best ways to forestall arrhythmia square measure are to take care of a healthy heart and forestall cardiovascular disease. If you have already got cardiovascular disease, monitor it and follow your treatment set up. make certain you perceive your treatment set up, and take all medications as prescribed.

Lifestyle changes to cut back the danger of cardiovascular disease could facilitate stopping heart arrhythmias which will cause arrhythmia. Take the subsequent steps:

  • Eat a healthy diet. Choose a diet wealthy in whole grains, lean meat, low-fat dairy farm, and fruits and vegetables. Limit salt, sugar, alcohol, and saturated fat and trans fats.

  • Exercise regularly. Try to exercise for at least 30 minutes on most days.

  • Maintain a healthy weight. Being overweight increases the risk of developing heart disease.

  • Keep blood pressure and cholesterol levels under control. Make lifestyle changes and take medications as prescribed to control high blood pressure (hypertension) or high cholesterol.

  • Stop smoking. If you smoke and can't quit on your own, talk to your health care provider about strategies or programs to help break the smoking habit.

  • Drink in moderation. If you decide on drinking alcohol, do so moderately. For healthy adults, meaning up to at least one drink daily for girls and up to 2 drinks daily for men. for a few health conditions, it's suggested that you simply fully avoid alcohol. raise your health care supplier for recommendations specific to your condition.

  • Don't use illegal drugs or stimulants, such as cocaine. Talk to your health care provider about an appropriate program for you if you need help ending illegal drug use.

  • Use medications with caution. Some cold and cough medications contain stimulants that will trigger a fast heartbeat. raise your health care supplier that medications you wish to avoid.

  • Limit caffeine. If you drink caffeinated beverages, do so in moderation (no more than one to two beverages daily).

  • Manage stress. Find ways to help reduce emotional stress. Getting more exercise, practicing mindfulness and connecting with others in support groups are some ways to reduce stress.

  • Go to scheduled checkups. Have regular physical exams and report any changes in your heartbeat to your health care supplier. If your symptoms amend or exasperate otherwise you develop new ones, tell your health care supplier straightaway.

Diagnosis Tachycardia

A thorough physical test, medical record and testing are needed to diagnose cardiac arrhythmia.Note: things inside this content were created before the coronavirus illness 2019 (COVID-19) pandemic and don't demonstrate correct pandemic protocols. Please follow all suggested Centers for illness management and interference pointers for masking and social distancing.To diagnose cardiac arrhythmia, a health care supplier can typically do a physical test and raise questions about your symptoms, health habits and medical record.

Grammar Check 


Tests, together with viscus imaging tests, are also done to verify a strangely quick heartbeat and appearance for conditions that may cause associate degree irregular regular recurrence (arrhythmia). Tests to diagnose cardiac arrhythmia might include:

  • Electrocardiogram (ECG or EKG). This fast and painless take a look at measures the electrical activity of the guts. Throughout AN EKG, sensors (electrodes) are hooked up to the chest and typically to the arms or legs. AN EKG measures the temporal order and period of every electrical revolution. Your health care supplier will rummage around for signal patterns to work out the sort of cardiac arrhythmia and the way issues within the heart could also be inflicting the quick vital sign.
    Some personal devices, like smartwatches, provide cardiogram watching. raise your health care supplier if this can be AN choice for you. 

  • Holter monitor. Your health care supplier might suggest watching your heartbeat reception. This transportable graphical record device is often worn on a daily basis or a lot to record the heart's activity throughout daily activities. 

  • Event monitor. This portable ECG device is intended to be worn for up to 30 days or until you have an arrhythmia or symptoms. You typically press a button when symptoms occur.

  • Echocardiogram. A sonogram uses sound waves to form footage of the center in motion. It will determine issues with blood flow, the center valves and therefore the muscle. 

  • Chest X-ray. A chest X-ray can show the condition of the heart and lungs.

  • Cardiac magnetic resonance imaging (MRI). A cardiac MRI can provide still or moving pictures of blood flow through the heart. This test is most often done to determine a cause of ventricular tachycardia or ventricular fibrillation.

  • Computerized tomography (CT). CT scans mix many X-ray pictures to produce an additional elaborated cross-sectional read of the realm being studied. A CT scan of the guts (cardiac CT) could also be done if a health care supplier is searching for a reason behind cavity arrhythmia. 

  • Coronary angiogram. A coronary X ray is completed to examine for blocked or narrowed blood vessels within the heart. It uses a dye and special X-rays to indicate the within of the coronary arteries. A coronary X ray is also done to see at the heart's blood supply in those who have cavity arrhythmia or fibrillation. 

  • Electrophysiological (EP) testing and mapping. This test, conjointly referred to as Associate in Nursing EP study, could also be done to substantiate a diagnosing of arrhythmia or to see wherever within the heart the faulty communication happens. Associate in Nursing EP study is usually accustomed to diagnose isolated arrhythmias. Less usually, it's going to be accustomed to measuring sinus arrhythmia.
    In this check, a health care supplier threads skinny, versatile tubes (catheters) tipped with electrodes through the blood vessels to totally different areas inside the guts. Once in situ, the electrodes will map the unfold of electrical signals through the guts. 

  • Stress test. Some kinds of arrhythmia square measure triggered or worsened by exercise. Throughout an assay, the heart's activity is usually monitored whereas riding on a stationary bicycle or walking on a treadmill. different heart tests could also be finished as an assay. If you've got exertion, a drug could also be given to stimulate the center during a manner that is the same as exercise. 

  • Tilt table test. This check is typically accustomed to facilitate higher perception however arrhythmia contributes to fainting. pulse and ara} are monitored whereas lying flat on a table. Then, beneath careful oversight, the table is tipped to a grip that mimics standing. The health care supplier watches however the guts and also the systema nervosum that controls it answer the changes in position. 

Treatment Tachycardia

The goals of arrhythmia treatment are to slow a fast heartbeat once it happens and to forestall future episodes of a quick pulse rate.

If another medical condition is inflicting arrhythmia, treating the underlying drawback could scale back or forestall episodes of a quick heartbeat.

Slowing a fast heart rate

A fast pulse could correct itself. However generally medication or alternative medical treatments are required to weigh down the heartbeat.

Ways to slow a quick pulse include:

  • Vagal maneuvers. Vagal maneuvers embrace coughing, bearing down as if having a shitting associate degreed golf stroke an ice gain the face. Your health care supplier might raise you to perform these specific actions throughout an associate degree episode of a quick heartbeat. These actions have an effect on the nervus vagus that helps manage the heartbeat. 

  • Medications. If vagal maneuvers don't stop the fast heartbeat, medication may be needed to restore the heart rhythm.

  • Cardioversion. This process is typically done by causing electrical shocks to the center through sensors (electrodes) placed on the chest. The shock affects the heart's electrical signals and restores a standard heartbeat. Cardioversion is usually used once emergency care is required or once pneumogastric maneuvers and medications do not work. It is also attainable to try to do cardioversion with medications. 

Preventing future episodes of a fast heart rate

The treatment of arrhythmia involves taking steps to forestall the guts from beating too quickly. This might involve medication, ingrained devices, or different surgeries or procedures.

  • Medications. Drugs to control the heart rate and restore a normal heart rhythm are typically prescribed for most people with tachycardia.

  • Catheter ablation. In this procedure, a health care supplier threads one or a lot of skinny, versatile tubes (catheters) through AN artery, typically within the groin, and guides them to the guts. Sensors (electrodes) on the tip of the tubing use heat or cold energy to form little scars within the heart to dam irregular electrical signals and restore the guts rhythm. It's typically done once an additional sign pathway is accountable for AN enlarged pulse rate.
    Catheter ablation does not need surgery to access the guts, however it should be done at a similar time as alternative heart surgeries. 

  • Pacemaker. A pacemaker may be a little device that is surgically established below the skin within the chest space. Once the device senses an irregular heartbeat, it sends an electrical pulse that helps the guts resume the right rhythm. 

  • Implantable cardioverter-defibrillator (ICD). Your health care supplier could advocate this device if you are at high risk of developing chamber cardiac arrhythmia or arrhythmia.
    An ICD may be a powered unit that is deep-rooted below the skin close to the bone — almost like a pacemaker. The ICD endlessly monitors the center rhythm. If the device detects an irregular heartbeat, it sends out low- or high-energy shocks to reset the heart's rhythm. 

  • Maze procedure. In this procedure, a MD makes small incisions within the higher half the guts (atria) to make a pattern (or maze) of connective tissue. The heart's signals cannot experience connective tissue. Therefore the maze will block stray electrical heart signals that cause some varieties of cardiac arrhythmia. 

  • Surgery. Sometimes heart surgery is also required to destroy an additional electrical pathway inflicting arrhythmia. Surgery is typically done once|only|only if} alternative treatment choices do not work or when surgery is required to treat another heart disorder.
    An implantable device, like a pacemaker or implantable cardioverter-defibrillator (ICD), is also accustomed to treat some styles of arrhythmia.

Lifestyle and home remedies

If you have tachycardia or any type of heart disease, your health care provider will likely recommend following a heart-healthy lifestyle. Take these steps:

  • Eat a healthy diet

  • Don't smoke

  • Get regular exercise

  • Maintain a healthy weight

  • Limit or avoid alcohol

Alternative medicine

Stress-relief techniques, such as meditation and yoga, might help slow the heartbeat and reduce tachycardia symptoms

Coping and support

If you have a plan in place to manage an episode of a fast heartbeat, you may feel calmer and more in control when one occurs. Ask your healthcare provider:

  • How to take your pulse and what heart rate is best for you

  • When and how to use vagal maneuvers, if appropriate

  • When to call a healthcare provider

  • When to seek emergency care

Seeking support from family and friends also may help reduce stress and better manage tachycardia.

Preparing for your appointment

If you've got arrhythmia, you will likely be spoken to by a doctor trained in heart conditions (cardiologist).

Because there is usually heaps to debate, it is a sensible plan to be ready for your appointment. Here's some info to assist you make preparations for your appointment, and what to expect from the health care supplier.

What you can do

Make a list ahead of time that you can share with your healthcare provider. Your list should include:

  • Any symptoms, including those that may seem unrelated to your heart

  • Key personal information, including any major stresses or recent life changes

  • All medications you take and the dosages, including vitamins and supplements and drugs bought without a prescription

  • Questions to ask your healthcare provider

Basic questions to ask your health care provider include:

  • What is the likely cause of my fast heart rate?

  • What kinds of tests are needed?

  • What's the most appropriate treatment?

  • What kind of risks does my heart condition create?

  • How will we monitor my heart?

  • How often will I need follow-up appointments?

  • How will other conditions I have or medications I take affect my heart problem?

  • Do I need to restrict my activities?

  • Are there any brochures or other printed material that I can take home with me? What websites do you recommend?

In addition to the questions that you've prepared to ask your health care provider, don't hesitate to ask additional questions.

What to expect from your doctor

Your health care provider is likely to ask you a number of questions. Being ready to answer them may save time to go over any details you want to spend more time on. Your health care provider may ask:

  • When did you first begin having symptoms?

  • How often have you had episodes of a fast heartbeat?

  • How long have the episodes lasted?

  • Does anything, such as exercise, stress or caffeine, seem to trigger or worsen episodes?

  • Does anyone in your family have heart disease or a history of irregular heart rhythms (arrhythmias)?

  • Has anyone in your family had cardiac arrest or died suddenly?

  • Do you smoke?

  • How much alcohol or caffeine do you use, if any?

  • Do you use stimulant drugs?

  • Are you being treated for high blood pressure, high cholesterol or other conditions that may affect your heart health?

  • What medications do you take for these conditions, and do you take them as prescribed?

General summary

  1. Tachycardia is a fast heart rate and can be either harmful or benign Characterized by heartbeats that are at least 10 to 15 beats faster than the normal resting heartbeat tachycardias can lead to palpitations angina and shortness of breath Common types include supraventricular tachycardia (SVT) atrial fibrillation atrial flutter ventricular tachycardia (VT) and paroxysmal supraventricular tachycardia (PSVT) Diagnosing the exact type will help determine the best course of treatment for your particular case Treatment options range.
