The atrioventricular delay Refractory periods of single chamber pacemakers Refractory periods of dual chamber pacemakers BVPA The safety window VRP ARP PVAB PVARP Protection against pacemaker-mediated tachycardias Onset, duration and rate of pacemaker-mediated tachycardia Prevention of onset of pacemaker-mediated tachycardia Diagnosis of pacemaker-mediated tachycardia by the pacemaker Anti-pacemaker-mediated tachycardia therapy THE ATRIOVENTRICULAR DELAY The AV delay determines the longest time interval between an atrial event and the programmed delivery of a ventricular pacing pulse. This interval is the electronic equivalent of the PR interval. The programming of the AV delay intends to ensure optimal mechanical coordination between atrial and ventricular contractions, whether the...
