Rapid Atrial Pacing-Induced Wenckebach Atrioventricular Block: A Poor Predictor of Permanent Pacemaker Need Post-TAVR

Key Result

Rapid atrial pacing-induced Wenckebach atrioventricular block is a poor predictor of the need for a permanent pacemaker following transcatheter aortic valve replacement.

Key Points

• The aim is to evaluate whether rapid atrial pacing-induced Wenckebach atrioventricular block can predict the need for a permanent pacemaker after TAVR.
• Conducted an observational study involving patients who underwent TAVR.
• Monitored heart rhythm changes during rapid atrial pacing.
• Assessed the incidence of permanent pacemaker implantation post-procedure.
• Wenckebach block was observed during pacing; however, it poorly predicted the need for a permanent pacemaker.
• Only a small percentage of patients requiring pacemakers had previously experienced Wenckebach block.
• Significant variability in patients' responses to pacing was noted.
