Longitudinal study reveals long-term outcomes of single atrial pacing in sick sinus syndrome, suggesting Wenckebach block rate provides reliable risk stratification.
Key Points
To assess the long-term clinical safety and efficacy of single atrial lead pacing in sick sinus syndrome using the Wenckebach block rate for atrioventricular block risk stratification.
Followed patients diagnosed with sick sinus syndrome treated with single-chamber atrial pacing.
Assessed electrophysiological parameters including baseline Wenckebach block rates to stratify the risk of subsequent atrioventricular conduction impairment.
Single-lead atrial pacing demonstrated sustained long-term efficacy and low complication rates in properly selected patients.
Pre-implantation Wenckebach block rate assessment effectively identified patients at low risk of developing high-grade atrioventricular block.
