Supports long-term DDD retention in most dual-chamber pacemaker recipients; leaves open optimal initial mode selection pending prospective trials.
Cohort (n=249)
No
Most patients with dual chamber pacemakers can be successfully maintained in DDD or an alternative atrial pacing mode over the long term, supporting the routine use of dual chamber pacing.
Ibrahim et al. (1995) conducted a cohort in Sick sinus syndrome and atrioventricular conduction disease requiring pacing (n=249). DDD mode pacing was evaluated on Cumulative survival of DDD mode at 60 months. DDD pacing mode was maintained in 83.5% of patients at 60 months, with atrial fibrillation being the most common reason for reprogramming to an alternative mode.
