An Electrocardiogram (ECG) is a non-invasive medical test that measures and records the electrical activity of the heart. The ECG is obtained by placing electrodes on the skin of the chest, arms, and legs. The electrodes detect the electrical signals generated by the heart and transmit them to a machine that records the signals on paper or a computer. The ECG can provide important information about the heart’s rhythm, rate, and conduction system, and is commonly used to diagnose and monitor various heart conditions, such as arrhythmias, heart attacks, and heart failure.
