Figure 3 – Representation of the pacing intervals of the pacemaker in DDD mode. A, atrial channel. Ap, atrial paced event. Ar, atrial event sensed in the refractory period. AVD, AV delay. LRL, lower rate limit. PVAB, post-ventricular atrial blanking. PVARP, post-ventricular atrial refractory period. TARP, total atrial refractory period. V, ventricular channel. VA interval, ventriculo-atrial interval. Vi, intrinsic ventricular event. Vp, ventricular paced event.





Keywords: Pacemaker, Artificial/adverse effects; Sick Sinus Syndrome/complications; Tachycardia/surgery.
