Electrocardiographic features: Various atrial site pacing

Indian Heart Journal, 2017
Atrial pacing is done for either symptomatic sinus node dysfunction (SND) or for maintenance of atrio-ventricular synchrony in a dual chamber pacemaker. Conventionally, atrial lead is placed in the right atrial appendage.

DDD Pacing Therapy Could Serve as a Dual Purpose Treatment in Hypertrophic Obstructive Cardiomyopathy —A Case Report Which Suggests the Importance of Lead Position and the Mechanism—

Journal of Arrhythmia, 2007
We treated a patient with hypertrophic obstructive cardiomyopathy (HOCM) who underwent DDD pacing therapy. He suffered from attacks of paroxysmal atrial fibrillation (PAF) complicated by sick sinus syndrome. Initially, we were unable to decrease the left

Leadless Atrial Pacing Targeting Bachmann's Bundle for Atrial Resynchronization

JACC Case Reports
Background Leadless pacemakers have transformed pacing by reducing risk for infection and lead-related complications. The feasibility of achieving leadless Bachmann's bundle area pacing (BBAP) for atrial resynchronization is not known.

Full-field optical coherence tomography using a fibre imaging bundle [PDF]

, 2006
An imaging fibre bundle is demonstrated for spatially-multiplexed probe beam delivery in OCT, with the aim of eliminating the mechanical scanning currently required at the probe tip in endoscopic systems.

An anatomy-guided whole-heart framework for computational modelling of the complete human cardiac conduction system

Frontiers in Cardiovascular Medicine
IntroductionComputational models of cardiac electrophysiology are increasingly used to investigate arrhythmia mechanisms and evaluate therapeutic interventions, yet most existing frameworks omit or oversimplify the cardiac conduction system, limiting ...

Small patients, significant findings: Electrophysiological properties of Bachmann's Bundle in pediatric patients.

Heart Rhythm
BACKGROUND Bachmann's Bundle (BB) may potentially play a role in the earlier onset and faster progression of atrial fibrillation (AF) in adult congenital heart disease (CHD) patients.

The Effects of Valvular Heart Disease on Atrial Conduction During Sinus Rhythm [PDF]

, 2019
Different arrhythmogenic substrates for atrial fibrillation (AF) may underlie aortic valve (AV) and mitral valve (MV) disease. We located conduction disorders during sinus rhythm by high-resolution epicardial mapping in patients undergoing AV (n = 85) or
