Atrial pacing: intracardiac conduction assessed by his bundle electrograms acquired from the permanent atrial electrode at implantation.
His bundle electrograms were recorded from conventional J-shaped atrial electrodes at implantation in twelve consecutive patients who had sinus node disorder. Five patients with impairment of atrioventricular conduction, received atrioventricular (DVI) pacemakers. His bundle recording by this method is simple and reliable, avoids the discomfort of the conventional technique, and represents a new application for the well established atrial "J" electrode.
