Witryna12 mar 2024 · The cardiac electrical signal controls the heartbeat in two ways. 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 … Witryna8.4 Summary. A. nerve impulse. is an electrical phenomenon that occurs because of a difference in electrical charge across the plasma membrane of a neuron. The. sodium-potassium pump. maintains an electrical gradient across the plasma membrane of a neuron when it is not actively transmitting a nerve impulse.
