Selective His Bundle Pacing (Top) The 12-lead electrocardiogram of a patient with complete heart block with narrow QRS escape rhythm. (Middle) Intracardiac electrogram recorded from the permanent His bundle pacing lead at the time of implantation. Note the His bundle electrogram (H) with injury current (arrow) followed by ventricular electrogram (V). (Bottom) His bundle pacing. The pacing spike (circle) is followed by an isoelectric interval of 40 ms and QRS complexes identical to the intrinsic rhythm.
