Is coronary sinus pacing a safe and effective method for atrial pacing in patients requiring pacemaker therapy?
Coronary sinus pacing is a feasible and generally safe method for atrial pacing, demonstrating success even in patients with atrioventricular block.
Coronary sinus pacing is a safe and effective means of pacing from the atrium. In 66 patients with an average follow-up of 14 months, there was a 14% failure rate. There were transient problems in 14% which were subsequently corrected. There was a 6% death rate which was not pacemaker related. Successful atrial pacing with thresholds up to 6.0 mA is feasible. Atrial pacing was successful in 18 of 19 patients with varying degrees of atrioventricular block. Our experience with a new electrode has been very satisfactory.
