WebMar 12, 2024 · First, since each electrical impulse generates one heartbeat, the number of electrical impulses determines the heart rate. In a normal sinus rhythm, that rate will be between 60 and 100 beats per minute. 2 The sinus node signal also controls electrical conduction as it "spreads" across the heart. WebThe cardiac events that occur from beginning of one heartbeat to the beginning of the next are called the cardiac cycle. The complete cycle involves both ventricular contraction and ventricular relaxation. Each cycle is initiated by spontaneous generation of an action potential in the SA node. pay ca sales and use tax
