Figure 1 A: The lower record shows the endocavitary signal sensed by electrode, showing the ventriculogram (V) and retrograde hisiogram (H). The upper records show the surface electrocardiogram (ECG). B: The top image shows the surface ECG; in the middle is the electrogram of the His-bundle electrode (EGM HIS); the bottom image shows the marker channel. Ap = auricular pacing; Vn = ventricular noise; Vr = ventricular refractory.
