Figure 1: (a) Displays the voltage map of the right atrial tunnel in anterior-posterior view. The tip of the pacemaker lead (white arrow) is visualized directly at the targeted pacing site. The green points mark areas with normal myocardium, i.e., local myocardia voltage ≥0.5 mV. (b) Shows the corresponding anterior-posterior fluoroscopic view with the atrial pacemaker lead (white arrow). The anatomy is outlined schematicly. Blue = Superior caval vein to right pulmonary vein anastomosis; Red = Right and left pulmonary arteries; Green = Stent graft connection between the intraatrial tunnel (yellow) and the pulmonary arteries (red); Yellow = Intraatrial tunnel; Bright green = Inferior caval vein
