WebIn third degree AV block, the atria and ventricles are not communicating at all. 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.

WebMuscle cells control your heart’s contractions. Your heart (cardiac) conduction system sends the signal to start a heartbeat. It also sends signals that tell different parts of your heart to relax and contract (squeeze). This process of contracting and relaxing controls blood flow through your heart and to the rest of your body.

WebThe intrinsic rate of the Purkinje fibers is 20-40 beats per minute which is what is causing the QRS complex to form. You would expect to see a ventricular rate of 20-40 beats per minute because that is how frequently the Purkinje fibers are going to fire.
