The ECG test is an excellent diagnostic tool for determining optimal cardiac function by measuring the time it takes for electrical pulses to flow through the heart. This allows the clinician to evaluate whether the heart is beating normally, quickly, slowly, or irregularly.

An electrocardiogram test, often known as an ECG, is a non-invasive and painless diagnostic process that aids in the diagnosis of heart problems as well as the monitoring of general heart health. Each heartbeat generates an electronic pulse that goes through the heart, therefore an ECG examines the electrical activity of the heart.

The electrical pulse contracts the artery muscles, which causes the heart to pump blood. The test detects and identifies any aberrant electrical activity that could indicate a heart problem or put you at risk of developing one. The ECG examines the electrical impulses produced by each heartbeat, which are shown on the ECG equipment as 'waves.' These impulses are classified into three waves:
