Temporary system for postoperative cardiac rhythm correction and cardiac stimulation, and electrode arrangement for use therewith

摘要

A post-surgical atrial cardioverting, atrial pacing, and ventricular pacing lead system (31; 131; 231; 331) provides for cardioverting the atria, pacing the atria, and/or pacing the ventricles of the heart of a post-surgical heart patient. The system includes a first lead (34; 134; 234; 334) and a second lead (36; 136; 236; 336) providing a pair of atrial cardioverting electrodes (38, 44; 138, 144; 238, 244; 338, 344), an atrial pacing electrode (40; 140; 240; 340), and a ventricular pacing electrode (42; 142; 242; 342). The electrodes are electrically isolated from each other. The system further includes anchors (50, 52, 54, 56, 58; 150, 152, 154, 156, 158; 250, 252, 254, 256, 258; 350, 352, 354, 356, 358) to releasably dispose the electrodes beneath the skin of the patient with each atrial cardioverting electrode electrically contacting a respective given one of the atria, the atrial pacing electrode electrically contacting one of the atria, and the ventricular pacing electrode electrically contacting a ventricle.
