Resting Electrocardiagram (ECG)

ECG

Resting Electrocardiogram (ECG) is a simple test which is commonly used for basic evaluation of cardiac status. It records intrinsic electrical activity of the heart by placing electrodes on the limbs and chest. The recorded signals provide useful information regarding previous damage to the heart muscles, enlargement of heart chambers and abnormalities in the electrical system of the heart.

The ECG is used in diagnosis and initial management of acute heart attack and palpitations. A normal resting ECG does not rule out a heart problem.
