WebThe beating of the heart is triggered by an electrical signal from the pacemaker. The pattern of electrical activity produced by each heart beat cycle is called the electrocardiogram or ECG (or EKG). One complete heart beat cycle is called a cardiac cycle (i.e., the systole, diastole, and the rest until the start of the next systole). WebIsovolumetric contraction.
