Key result
Biatrial pacing improved regional wall motion synchronicity compared to right atrial appendage pacing, significantly reducing the pacing spike to peak strain interval in the septal atrium (225.0 vs 267.2 ms, P<0.0001).
Why the study?
Does biatrial pacing improve atrial regional wall motion synchronicity compared to right atrial appendage pacing in patients with atrial fibrillation?
Does biatrial pacing improve atrial regional wall motion synchronicity compared to right atrial appendage pacing in patients with atrial fibrillation?
Absolute Event Rate: 225% vs 267.2%
p-value: p=<0.0001
Biatrial pacing improves the synchronicity of regional wall motion in both atria compared to right atrial appendage pacing, which may contribute to its preventive effects on atrial fibrillation.

Biatrial pacing may aid atrial synchrony in AF; leaves open impact on recurrence in prospective trials.
Matsumoto et al. (2006) studied Bradycardia-Tachycardia Syndrome / Atrial Fibrillation (n=6). Biatrial (BiA) pacing vs. Right atrial appendage (RAA) pacing was evaluated on Interval from pacing spike to peak strain in the septal atrium (p=<0.0001). Biatrial pacing improved regional wall motion synchronicity compared to right atrial appendage pacing, significantly reducing the pacing spike to peak strain interval in the septal atrium (225.0 vs 267.2 ms, P<0.0001).
