Why the study?
Does DDD pacing improve stroke volume compared to VVI pacing in patients equipped with pacemakers?
Does DDD pacing improve stroke volume compared to VVI pacing in patients equipped with pacemakers?
DDD pacing provides both short- and long-term hemodynamic benefits with increased stroke volume compared to VVI pacing, which can be optimized by individualizing the AV interval using Doppler echocardiography.
No takes yet. Share an insight, caveat, or question.
DDD pacing was associated with higher stroke volume than VVI; hypothesis-generating for AV optimization and requires randomized outcome trials.
Færestrand et al. (1985) studied this question.
