The electrocardiogram (ECG or EKG) is a diagnostic tool that is routinely used to assess the electrical and muscular functions of the heart. It helps to understand how the heart works. With each heartbeat, an electrical signal spreads from the top of the heart to the bottom. As it travels, the signal causes the heart to contract and pump blood. The process repeats with each new heartbeat.
Doctors use ECG to detect and study many heart problems, such as heart attacks, arrhythmias and heart failure. The test’s results also can suggest other disorders that affect heart function.
ECG is the basic tool in cardiology. These machines are available in all wards, OPD(s) and Emergency room. These machines are operated by skilled technicians.
