Prognostic benefits of His?Purkinje capture in physiological pacemakers for bradycardia

Journal of Cardiovascular Electrophysiology

Methods Consecutive patients with bradycardia indicated for pacing from 2016 to 2022 were prospectively followed for the clinical endpoints of heart failure (HF)-hospitalizations and all-cause mortality at 2 years. CSP should be preferred over VSP or RVP during pacing for bradycardia.

Comparative Analysis of Leadless Versus Transvenous Pacemakers in Non‐Heart Failure Patients: A Multicenter US Retrospective Study

Journal of Cardiovascular Electrophysiology

ABSTRACT Background Despite leadless pacemakers (LPMs) showing promise, real-world data comparing them to transvenous pacemakers (TV-VVI) are insufficient and often contradictory, especially in patients without major comorbidities like heart failure. Objectives Comparing LPMs with TV-VVIs in real-world patients without HF.

Predictive Role of Intraoperative Impedance in Midterm Pacing Threshold Elevation: Insights From Aveir VR Leadless Pacemaker Implantations

Journal of Cardiovascular Electrophysiology

LP, leadless pacemaker; PCT, pacing capture threshold; AUC, area under the curve. ABSTRACT Introduction Leadless pacemakers (LPs) are a valuable treatment for bradycardia, with the Aveir offering advanced features, including a protective sleeve and active fixation.

Assessment of ventricular electrical heterogeneity in left bundle branch pacing and left ventricular septal pacing by using various electrophysiological methods

Journal of Cardiovascular Electrophysiology

Methods Thirty-seven patients with a pacemaker indication for bradycardia or cardiac resynchronization therapy underwent LBBAP implantation. ECG, vectorcardiogram, ECG belt and UHF-ECG signals were recorded during RVP, LVSP and LBBP, and intrinsic activation.

Paced QRS morphology mimicking complete left bundle branch block induced by right ventricular pacing is associated with pacing?induced cardiomyopathy

Journal of Cardiovascular Electrophysiology

Complete left bundle branch block (CLBBB)-like QRS morphology of right ventricular pacing at pacemaker implantation satisfying the American Heart Association/American College of Cardiology Foundation/Heart Rhythm Society criteria of CLBBB was associated with development of pacing induced cardiomyopathy.

Cardioneuroablation for pediatric patients with functional sinus node dysfunction and paroxysmal atrioventricular block

Journal of Cardiovascular Electrophysiology

Abstract Introduction Severe transitory episodes of bradycardia with subsequent syncope in children are common, and generally portend a benign prognosis. Conclusion CNA may be an effective alternative to pacemaker implantation in pediatric patients with syncope or significant symptoms secondary to functional SP or AVB. s (range 0.8–2.2)
