WebThis prevents the atrioventricular node from generating a spontaneous rhythm under normal conditions, since it remains refractory at rates <55 beats per minute. If the sinoatrial node … The AV node's normal intrinsic firing rate without stimulation (such as that from the SA node) is 40–60 times/minute. This property is important because loss of the conduction system before the AV node should still result in pacing of the ventricles by the slower pacemaking ability of the AV node.
