Safety and efficacy of automatic capture threshold algorithms in left bundle branch area pacing

Abstract Funding Acknowledgements Type of funding sources: None. Background Automatic capture algorithms periodically measure the minimal quantity current needed for pacing, self-adjusting output to guarantee consistent myocardial capture, enhancing patient safety in case an unexpected rise threshold and reducing drain. Left bundle branch area pacing (LBBAP) is emerging conduction system (CSP) technique which overcomes technical issues weaknesses pure Hisian pacing. Purpose The aim our study was evaluate efficacy automatic a population patients with LBBAP. Methods We prospectively enrolled receiving LBBAP different companies provide material) we evaluated accuracy at 24 hours 3 months after implantation. Moreover, when available, home monitoring used follow up. Results included 45 consecutive who underwent from January 2022 August 2022. At hours, mean manual 0.5±0.2 V 0.4 msec, while 0.5±0.3 msec (p = 0.30). 0.6±0.2V vs 0.25). Sensing impedance measures where optimal improved during up, respectively 13.7±4.8 mV 13.9±4.8 0.6) 460.1±130 Ohm 417.1±96.2 0.1). Conclusion are able effectively both acute phase possibility safely use algorithms, thus preserving battery protecting against possible future rises, represents another advantage
