ABSTRACT:
A J-shaped atrial electrode lead having a pliant tube encasing a spiral wound conductor. A curved, resilient reinforcing member surrounding a portion of the conductor curves the conductor to conform with the shape of the origin of the crista terminalis of the right atrium to position an electrode tip in electrical contact with the junction of the crista terminalis and the superior margin of the right atrial appendage. The lead can be electrically bipolar or unipolar and includes tines adapted for engagement in the right atrial appendage, and an improved proximal portion for connection with a pacemaker circuit module.
