The ____ send(s) out electrical impulses to initiate depolarization. Which of the following is a life-threatening dysrhythmia that results in no cardiac output Which of the following dysrhythmias is due to a heartbeat originating in the ventricles that occurs early in the cycle and is followed by a pause before the next cycle?
