ECG or echocardiogram is a test to really look at the smooth running of the heart. This is the simplest test to keep an eye on the working of the heart, its muscles, and its valves.

An ECG is a quick, painless and harmless procedure that checks how your heart is functioning by measuring the electrical activity of the heart.

In an ECG test, the electrical impulses made while the heart is beating are recorded and usually shown on a piece of paper. This is known as an electrocardiogram, and records any problems with the heart's rhythm, and the conduction of the heart beat through the heart which may be affected by underlying heart disease.

ECG is a non-invasive and painless process that helps to diagnose many heart problems.

• Abnormality in your arrhythmias (Heart rhythm)
