ECG full form in medical term is an Electrocardiogram that is used to check the heart rhythm or heartbeats of a person. Many people confuse an electrocardiogram with an echocardiogram, which is a scan of the heart. The human heart works because of the electrical signals generated by the sinus node. But for some reasons, the heartbeat can be affected, and during the ECG test, an electrical device is used which shows heartbeats in the form of a continuous graph on the screen. This can help in detecting some fatal heart diseases.
People suffering from arrhythmias have very irregular heartbeats. Some people with arrhythmias have very slow or very fast heartbeats, and with an ECG that irregularity can be monitored. In other cases, like coronary heart disease, an ECG test can be quite effective. Sometimes it happens when coronary heart disease causes heart attacks, and in the case of an acute heart attack, doctors continuously monitor a patient’s heartbeat to monitor heart functions. With the help of ECG tests, doctors can also detect fatal defects in a patient’s heart like cardiomyopathy, which occurs because the heart walls become thicker and bigger in size.
