WebApr 10, 2015 · Intrinsic rhythmicity of denervated SA- node is 90. impulses/min, while that of AV- node is 60. impulses/min. However, vagal tone controls SA- node to become 70. impulses/min, & AV- node to 40 impulses/min. If SA- node activity is depressed by a disease, AV-node takes over & becomes the pacemaker instead, leading to bradycardia.
