WebMar 12, 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 … WebHeart Conduction System Cardiac muscle cells have the ability to conduct action potentials from cell to cell through the gap junctions of the intercalated disks. This conduction, however, cannot account for the ordered, synchronous contractions observed in the heart.
