The atria are using their pacemaker, the Sinoatrial (SA) node, which beats at 60-80 bpm, but since the conduction pathways for the electrical signal to pass on to the ventricles are blocked, the ventricles use their own intrinsic pacemaker. ferrero rocher 24 ct

"WebThe intrinsic rate determined by effector blockade was 142.9 +/- 7.2 (SE) beats/min in the dogs with intact cardiac innervation. When the same treatment was given after total surgical cardiac denervation, intrinsic rate was 97.9 +/- 4.8 beats/min. Intrinsic heart rate was significantly (P less than 0.05) lower in surgically denervated dogs. " - Intrinsic rate for the ventricles
