ECG
An ECG or an electrocardiogram test is a non-invasive and painless diagnostic procedure that helps in the detection of heart issues as well as monitoring the overall heart health.
An ECG monitors the electrical activity of the heart as each heartbeat generates an electronic pulse that travels through the heart.
The electrical pulse contracts the arterial muscles which in turn pump the blood from the heart. The test detects and identifies any abnormal electrical activity, indicative of a heart illness or the risk of one.
The ECG checks for the electrical impulses made with each heartbeat which is displayed as ‘waves’ on the ECG machine. These impulses are categorised in three waves, namely:
