Alternating Wolff-Parkinson-White (preexcitation) pattern.

abstract：OBJECTIVE:Assess effect of right ventricular pacing (RVP) on left ventricular (LV) activation in heart failure patients with left bundle branch block (LBBB). BACKGROUND:LV activation during RVP is regarded as similar to LBBB; hence novel CRT algorithms may avoid RVP by adopting "fusion" pacing with intrinsic RBB-media...
