Total atrial refractory period

Fig. 3.29 Loss of Biventricular Pacing. On the Y axis the atrial rate is shown. As the atrial rate exceeds the LRL, biventricular pacing is maintained. However, when the atrial rate reaches the TARP, which equals the sum of the PVARP and the AV interval, biventricular pacing will stop. However, biventricular pacing will not resume even after the atrial rate falls until the atrial rate reaches the intrinsic total atrial refractory period (ITARP), which is the sum of the PVARP and the PR interval.
