Refractory tachycardia
WebThe post-ventricular atrial refractory period (PVARP) is triggered by ventricular sensing or pacing and is implemented in DDD, DDI and VDD modes. Its main role is to prevent the sensing of retrograde P wave that might trigger a pacemaker mediated tachycardia in the P wave synchronous modes.
