What Is Echocardiography?
Echocardiography, a diagnostic method that uses ultrasound (excessive-frequency sound waves) to provide a photograph of the internal systems of the coronary heart. A piezoelectric transducer located on the floor of the chest emits a quick burst of ultrasound waves and then measures the reflection, or echo, of the sound as it bounces lower back from cardiac systems which includes the coronary heart valves and the muscle wall. The transducer does this by converting electric impulses into a slim ultrasonic beam that penetrates body tissues. The meditated sound waves are detected by means of a receiver that is also positioned on the chest. The waves are transformed lower back into electric impulses and are projected on the display screen of a cathode-ray oscilloscope.

In this trendy type of echocardiogram:
A technician (sonographer) spreads gel on a tool (transducer).
The sonographer presses the transducer firmly against your skin, aiming an ultrasound beam via your chest in your heart.
The transducer statistics the sound wave echoes from your heart.
A laptop converts the echoes into shifting photos on a display.
If your lungs or ribs block the view, you can want a small quantity of an improving agent injected via an intravenous (IV) line. The improving agent, which is normally secure and well tolerated, will make your heart's systems show up extra honestly on a reveal.

Pumping strength. The measurements received from an echocardiogram consist of the share of blood that is pumped out of a stuffed ventricle with each heartbeat (ejection fraction) and the quantity of blood pumped by way of the heart in a single minute (cardiac output). A coronary heart that is not pumping enough blood to fulfill your frame's wishes can cause signs and symptoms of coronary heart failure.
Damage to the heart muscle. An echocardiogram helps your medical doctor decide whether all parts of the coronary heart wall are contributing commonly to your heart's pumping interest.
