Abstract: A single-pass atrio-ventricular (A-V) pacing lead includes an elongated main lead body having an atrial electrode at the distal end thereof, and includes a ventricular branch which departs from the main lead body just proximal to the tip of the atrial electrode. The ventricular branch has a ventricular electrode at its distal tip. The main lead body includes a preformed "J"-shaped portion which, following proper implantation, projects the atrial electrode against a wall of the atrial appendage. The ventricular branch includes a preformed bend which curves in the opposite direction of the J-shaped portion so as to maintain the ventricular branch generally away from the wall of the atrial appendage. The lead includes a single lumen which extends through both the main lead body and the ventricular branch, allowing the lead to be implanted using a single stylet.
