IBHRE Test 16 Questions and Answers 100% Solved The clinician programs the paced AV delay in the pacemaker to 200ms. What would be a recommended value for programming a sensed AV delay? 175 Why is it important to optimize the AV delay when programming a pacemaker? To enhance hemodynamics To allow sufficient time for ventricular filling and atrial kick To prevent unnecessary ventricular pacing TARP is the total atrial refractory period. What does it consist of? AV delay + PVARP What...
