Why the study?
Does cardiac output-based programming of AV interval improve cardiac output compared to empirically programmed AV interval in patients with dual chamber pacemakers due to AV block?
Population
19 patients with implanted dual chamber pacemakers due to AV block but otherwise normal hearts.
Comparison
Cardiac output-based programming of… vs Empirically programmed AV interval.
Design
Cross-sectional

May enhance hemodynamics with individualized AV programming in dual-chamber pacemakers; hypothesis-generating and requires randomized confirmation.
Does cardiac output-based programming of AV interval improve cardiac output compared to empirically programmed AV interval in patients with dual chamber pacemakers due to AV block?
Optimizing AV intervals using serial cardiac output measurements significantly improves cardiac hemodynamics compared to empirical programming in patients with dual-chamber pacemakers.
