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.
