Figure 3

The left panel shows the signal from ablation catheter at the His position during activation mapping of PVC-2. Note the His potential at the distal bipole during sinus beat (blue arrow). The right panel shows in magnification the timing of the corresponding local electrogram during PVC-2 indicating zero prematurity in relation to the QRS onset and absence of activation gradient between distal and proximal bipoles. Abbreviations as in FigureĀ 2.
