Key result
VVI pacing significantly reduced ventricular premature complexes by 26% (from 331 to 245/hour, p<0.001) compared to no pacing in patients with ventricular ectopic activity.

VVI pacing may suppress ectopy during VT testing; leaves open any role in clinical management or outcomes.
Does VVI pacing at physiologic rates reduce ventricular ectopic activity in patients undergoing testing for VT control?
Effect estimate: 26% reduction
Absolute Event Rate: 245% vs 331%
p-value: p=<0.001
Fisher et al. (1987) studied Ventricular ectopic activity (n=18). VVI pacing vs. Absence of pacing was evaluated on Ventricular premature complexes (VPCs) per hour (26% reduction, p=<0.001). VVI pacing significantly reduced ventricular premature complexes by 26% (from 331 to 245/hour, p<0.001) compared to no pacing in patients with ventricular ectopic activity.
