case_images: This figure shows 12-lead electrocardiograms and intracardiac electrograms from the His
  bundle pacing (HBP) lead at baseline and from non-selective HBP (right ventricular
  septum + His capture) to selective HBP (His capture only). Note His potential at
  baseline on the pacing lead (arrow).

case_images: The threshold of selective HBP was 1.1 V@1 ms; the impedance was 561 ohms, the sensing was 5.3 mv, and the QRS duration (QRSd) was 112 ms (Figure 1).
case_images: This figure shows 12-lead electrocardiograms and intracardiac electrograms from the
  left bundle branch pacing (LBBP) lead at baseline and from non-selective LBBP (left
  ventricular septum + LBB capture) to left ventricular septal pacing (left ventricular
  septum capture only). Note His and left bundle branch (LBB) potentials at baseline,
  retrograde His (RH) potential on HBP lead.

case_images: The lead advancement was stopped until the left bundle branch (LBB) potential was observed. The threshold of LBBP was 0.8 V@0.4 ms; the impedance was 542 ohms, the sensing was 12.7 mv, and the stimulus-QRSend duration (s-QRSend) was 144 ms (Figure 2).
case_images: This figure shows the atrioventricular node ablation site and the distance to the tip
  of His bundle pacing lead (arrow) using fluoroscopic images in the right anterior
  oblique projection 30 .
