A resting electrocardiogram (ECG or EKG) is a noninvasive procedure that measures the electrical activity of your heart. During this test, electrodes are placed on your chest, arms, and legs to detect the tiny electrical signals produced by your heart as it beats. These signals are then amplified and recorded on graph paper or displayed on a comput… Read More
