3 Figure 2 The tracings from top to bottom are the surface electrocardiogram leads I, aVF, V, and V6, followed by intracardiac electrogram recordings from the right atrium (RA), His bundle, coronary sinus (CS), and right ventricular apex (RVa) recordings. A: Sinus rhythm. B: Right atrial pacing with maximal pre-excitation with short HV interval.
