Key result
Dual chamber pacing with varying AV intervals showed overall improvement in cardiac function compared to ventricular pacing in the majority of patients, regardless of left ventricular function.

May support dual-chamber pacing in selected patients; leaves open randomized confirmation of AV interval optimization.
Observational
Does dual chamber pacing with varying AV intervals improve cardiac function compared to ventricular pacing in patients requiring pacing?
Dual chamber pacing with shorter AV intervals improves cardiac function compared to ventricular pacing, particularly during physiological stress.
Leman et al. (1985) reported an observational. Dual chamber pacing with varying AV intervals vs. Ventricular pacing was evaluated on Changes in left ventricular ejection fraction, end diastolic volume, and stroke volume. Dual chamber pacing with varying AV intervals showed overall improvement in cardiac function compared to ventricular pacing in the majority of patients, regardless of left ventricular function.
