ATRIO-VENTRICULAR CARDIAC PACING CATHETER ABSTRACT OF THE DISCLOSURE A cardiac pacing catheter system includes a main guiding catheter and a pair of electrical leads adapted to make direct electrical contact with the ventricle and the atrium of the patient's heart. The main catheter has a pair of lumens which guide and contain the ventricular and atrial leads. Each of the leads can be advanced and manipulated separately and independently within the main catheter body. The lumen for the ventricular lead exits at a port at the distal end of the main catheter body. The lumen for the atrial lead exits along a port at the side of the catheter, at a location proximal of the distal end. The atrial lead is spring-like and is formed with a J-shaped curve at its distal end which, when it exits from the catheter lumen, will assume the J-shaped configuration so that it may be manipulated into direct contact with the more upwardly disposed roof regions of the atrium. In use the catheter is advanced, with the leads retracted, to the entry to the right atrium. The ventricular lead then is extended to the ventricular apex and secured. the atrial lead then is advanced, assumes its J-shaped configuration and is adjusted into position to contact the roof of the atrium.
