Observation and analysis of atrioventricular synchrony in patients implanted with leadless pacemaker Micra AV
摘要
Abstract
Objective To observe the actual atrioventricular synchrony after Micra AV implantation.Methods In retrospective cohort study,12 consecutive patients who were implanted with VDD leadless pacemakers in Beijing Hospital from August 2022 to April 2023 were included.General clinical data were collected through the electronic medical record system,and the electrical parameters related to pacemakers were observed in the outpatient follow-up for 6 months.The percentage of atrioventricular synchrony in each patient were analyzed.For patients with low atrioventricular synchrony,Holter was re-examined and the reasons for low atrioventricular synchrony were explored in combination with the built-in data of pacemaker,and programmed management was carried out.Results Twelve patients were enrolled,and the median initial AVS was 74.3%.Patients with complete third degree or high atrioventricular block,relatively high A4 threshold,and ventricular rate of 50-80 beats/min(4 cases)had a higher rate of physiologic pacing of AVS(84.1%-87.0%).The percentage of AVS decreased(66.0%-76.6%)in patients with low atrioventricular block,sinus node dysfunction,segmental wall motion abnormality,and left atrial enlargement(4 cases),and the percentage of AVS decreased significantly(27.8%-50.1%)in patients with atrial premature beat,sinus tachycardia,and paroxysmal atrial fibrillation(4 cases).The use of Holter monitor has certain guiding significance for optimal interrogation of AVS.Conclusions Patients with normal sinus node function,third degree or high atrioventricular block,relatively high A4 threshold,and ventricular rate of 50-80 beats/min are more likely to achieve physiological pacing of AVS.As an auxiliary tool,Holter monitoring provides a more comprehensive and reliable source for optimal device interrogation.关键词
