Definition: A recording of the electrical activity of the heart. Within each heartbeat, electrical waves travel through the heart. For a normally functioning heart, the P wave indicates atrial contraction, then after a short pause, the QRS complex indicates ventricular contraction and then a T wave marks the relaxation of the ventricles. EKGs are recorded on a chart paper, displayed on a monitor or digitally captured.
