An electrocardiogram (ECG), also known as an electrocardiograph, is a valuable tool used to assess the rhythmic activity of the heart. During a resting ECG, a subject remains still while electrodes are placed on their chest, arms, and legs. These electrodes measure the subtle electrical signals generated by the heart as it beats.

A resting electrocardiogram (ECG), also known as, is a simple test that measures the electrical activity of your heart. During this test, you will lie down in a calm environment while electrodes placed to your chest, arms, and legs. These sensors transmit the ECG's signals to a machine that creates a waveform representation of your heart rhythm. A
