Interesting electrophysiological phenomenon during positioning of the lead deep inside the septum

Annals of Noninvasive Electrocardiology, 2022
Left bundle branch pacing (LBBP) is a developing physiological pacing technique. Wu et al. proposed that direct LBB capture could be confirmed by recording retrograde His potential (PoReHis) and mapping of the left conduction system potential.

Permanent biventricular ICD-implantation in a heart failure second re-do-CABG patient : a case report [PDF]

, 2009
Biventricular pacing has been suggested in end-stage heart failure. We present a 59-year-old patient undergoing second re-do CABG (coronary artery bypass graft) and carotid artery endarterectomy. Ejection fraction was 15%, QRS-width 175 ms. Following the

Left ventricular epicardial pacing achieved hyper‐responsiveness in young children with dilated cardiomyopathy with left bundle branch block

ESC Heart Failure, 2021
Aims The management of heart failure (HF) in young children is challenging. The present study aimed to clarify the effect of left univentricular epicardial pacing on dilated cardiomyopathy with left bundle branch block (LBBB) in children.

Use of acoustic cardiography to assess left ventricular electromechanical synchronization during left bundle branch pacing

Heart Rhythm O2, 2023
Background: Left bundle branch pacing (LBBP) is a physiological pacing that captures the main left bundle or its proximal branch. Electromechanical activation time (EMAT) is an acoustic cardiographic metric that provides a simple method for evaluating ...

Optimal Cardiac Resynchronization Therapy with Conduction System Pacing Guided by Electro-Anatomical Mapping: A Case Report

Journal of Cardiovascular Development and Disease, 2023
Introduction: Biventricular pacing has been the gold standard for cardiac resynchronization therapy in patients with left bundle branch block and severely reduced left ventricular ejection fraction for decades.

Characteristics of intracardiac electrogram of the interventricular septum in the left bundle branch pacing

BMC Cardiovascular Disorders, 2022
Background Left bundle branch pacing (LBBP) has become a hot topic in the field of physiological pacing. However, only a few studies have described the characteristics of the intrinsic intracardiac electrogram (EGM) while placing the left bundle branch ...

Left Bundle Branch Pacing: Current Knowledge and Future Prospects

Frontiers in Cardiovascular Medicine, 2021
Cardiac pacing is an effective therapy for treating patients with bradycardia due to sinus node dysfunction or atrioventricular block. However, traditional right ventricular apical pacing (RVAP) causes electric and mechanical dyssynchrony, which is ...

Radial left ventricular dyssynchrony by speckle tracking in apical versus non apical right ventricular pacing- evidence of dyssynchrony on medium term follow up [PDF]

Journal of Cardiovascular and Thoracic Research, 2016
Introduction: To study effects of various sites of right ventricular pacing lead implantation on left ventricular function by 2-dimensional (2D) speckle tracking for radial strain and LV dyssynchrony.

Separated right and left ventricular excitation during right ventricular septal pacing in a patient with narrow QRS wave: A case report [PDF]

, 2014
Introduction. Right ventricular septal pacing is thought to be better than right ventricular apical pacing for shortening the QRS duration and for preserving left ventricular function.

Permanent Cardiac Pacing in Children: A 30-Year Follow-Up Retrospective Study in a Single Pediatric Asian Center. [PDF]

J Arrhythm
This 30‐year retrospective study of pediatric permanent pacing found acceptable long‐term device complication rates, with epicardial leads used predominantly. Pacing‐induced cardiomyopathy occurred only in children with congenital heart disease, highlighting the need for individualized pacing strategies in this cohort and long‐term echocardiographic ...
