Hypothesis
Can biatrial pacing effectively prevent atrial fibrillation after coronary artery bypass surgery?
Conclusion
Biatrial pacing is effective in reducing the incidence of atrial fibrillation after CABG surgery and shortens hospital stay.
Supporting Evidence
- Atrial fibrillation occurs in up to 40% of patients after CABG surgery.
- Biatrial pacing reduced AF incidence to 17.5% compared to 30% with LA pacing and 45% in the control group.
- Patients receiving both amiodarone and pacing had significantly lower AF rates than those receiving placebo.
Takeaway
This study shows that using two sites for pacing the heart can help stop a common problem after heart surgery called atrial fibrillation, which can make patients stay in the hospital longer.
Methodology
A prospective, randomized, double-blinded, placebo-controlled study comparing biatrial pacing with left atrial pacing and no pacing.
Limitations
The study may not address cost-effectiveness and the role of single-site pacing.
Participant Demographics
Patients undergoing CABG surgery, well matched in age, LV function, and use of beta-blockers.
