"WebHowever, this intrinsic rate is under the control of autonomic nerves and circulating hormones, which increase or decrease this rate. At rest, the sinoatrial rate, and therefore heart rate when the heart is in sinus rhythm (i.e., controlled by SA node), is usually 60-80 beats/minutes (bpm), which is well below the intrinsic firing rate.
