The Role of Electrophysiologic Study in Device Selection for Leadless Atrial Pacing [PDF]

Texas Heart Institute Journal
The AVEIR DR (Abbott Medical) was the first dual-chamber leadless pacing system approved by the US Food and Drug Administration. Many patients with sinus node dysfunction have physiologically normal atrioventricular conduction, so an atrial-only pacing ...

Effects of early afterdepolarizations on excitation patterns in an accurate model of the human ventricles [PDF]

, 2017
Early Afterdepolarizations, EADs, are defined as the reversal of the action potential before completion of the repolarization phase, which can result in ectopic beats.

Biventricular versus Conduction System Pacing after Atrioventricular Node Ablation in Heart Failure Patients with Atrial Fibrillation

Journal of Cardiovascular Development and Disease, 2022
Conduction system pacing (CSP) modalities, including His-bundle pacing (HBP) and left bundle branch pacing (LBBP), are increasingly used as alternatives to biventricular (BiV) pacing in heart failure (HF) patients scheduled for pace and ablate strategy ...

Regulation of gap junction function; the role of nitric oxide. [PDF]

, 2013
Myocardial ischemia resulting from sudden occlusion of a coronary artery is one of the major causes in the appearance of severe, often life-threatening ventricular arrhythmias.

Nonlinear physics of electrical wave propagation in the heart: a review [PDF]

, 2016
The beating of the heart is a synchronized contraction of muscle cells (myocytes) that are triggered by a periodic sequence of electrical waves (action potentials) originating in the sino-atrial node and propagating over the atria and the ventricles ...

Implant, assessment, and management of conduction system pacing

European Heart Journal Supplements, 2023
Abstract His bundle pacing and left bundle branch pacing, together referred to as conduction system pacing, have (re)gained considerable interest over the past years as it has the potential to preserve and/or restore a more physiological ventricular activation when compared with right ventricular pacing and may serve as an alternative ...

His bundle pacing. Technical aspects and evidence base for use as an alternative to cardiac resynchronization therapy and conventional electrical pacing

Российский кардиологический журнал
His bundle pacing is a direct pacing of the specialized His-Purkinje conduction system with the aim of physiological ventricular activation, in contrast to the dyssynchronous activation by conventional myocardial pacing.In this review article on His ...

Complex patterns of spontaneous initiations and terminations of reentrant circulation in a loop of cardiac tissue

, 2008
A two-component model is developed that consists of a discrete loop of cardiac cells that circulates action potentials together with a cardiac pacing mechanism.
