Why the study?
Does dual-chamber pacing improve well-being and exercise capacity compared to single-chamber pacing in patients with high degree AV block?
Population
25 patients with high degree AV block who received either a DDD (n=23) or VDD pacemaker, mean age 66.7 years.
Comparison
Dual-chamber pacing mode (DDD or VDD) vs Single-chamber pacing mode for a 3-week period
Design
Other
Follow-up
3 weeks per pacing mode

May support dual-chamber pacing for well-being in AV block; leaves open randomized confirmation of exercise effects.
Does dual-chamber pacing improve well-being and exercise capacity compared to single-chamber pacing in patients with high degree AV block?
Dual-chamber pacing significantly improves subjective well-being and objective hemodynamic response during exercise compared to VVI pacing in patients with high-degree AV block.
Fromer et al. (1990) studied this question.
