The operation for implanting two pacemaker electrodes can be difficult and time-consuming because two separate veins must be identified and mobilized.
Describes a technique for transvenous insertion of double sets of permanent electrodes to address the technical challenges of dual-chamber pacing.
Difficulty mobilizing separate veins may limit dual-chamber pacing; leaves open whether proposed double-electrode techniques improve procedural success.
ALTHOUGH less than 3% of pacemaker implants performed today make use of the atrium, now that new and stable atrial appendage electrodes are available and there is also a growing awareness of their physiological and clinical advantages, it seems likely that interest in atrial pacing will grow. This statement is corroborated (Michael Bilitch, MD; Seymour Furman, MD; Victor Parsonnet, MD: Four-year results of a National Pacemaker Registry, unpublished data, July 1974 to June 1978). Some enthusiasts estimate that the atrium will be used for various forms of pacing, eg, fixed rate atrial pacing (AOO); inhibitory atrial pacing (AAI); triggered atrial pacing (AAT); atrial synchronous pacing (VAT); and bifocal sequential demand pacing (DVI),¹in more than one half of the patients requiring pacemakers.²,³ Unfortunately, the operation for implanting two electrodes can be difficult and time-consuming, because two separate veins must be identified and mobilized.

Victor Parsonnet (1980) studied Pacemaker implantation. Transvenous insertion of double sets of permanent electrodes was evaluated. The operation for implanting two pacemaker electrodes can be difficult and time-consuming because two separate veins must be identified and mobilized.
