Therapeutic Effect of His-Purkinje System Pacing Proportion on Persistent Atrial Fibrillation Patients With Heart Failure

Frontiers in Cardiovascular Medicine, 2022
BackgroundHis-Purkinje system pacing (HPSP) combined with atrioventricular node ablation is an effective therapy for atrial fibrillation (AF) patients with heart failure (HF). However, atrioventricular node ablation has some limitations and disadvantages.

Atrioventricular nodal reentry tachycardia treatment using CARTO 3 V7 activation mapping: a new era of slow pathway radiofrequency ablation is under coming

Frontiers in Cardiovascular Medicine, 2023
BackgroundSlow pathway (SP) ablation is the cornerstone for atrioventricular nodal reentry tachycardia (AVNRT) treatment, and a low-voltage bridge offers a good target during mapping using low x-ray exposure.

Mahaim fiber connecting the right atrium to the left ventricle: a case report

Journal of Arrhythmia, 2020
In the majority of cases presenting with the Mahaim fiber (MF), the MF connects the lateral right atrium (RA) to the right bundle branch or the right ventricle.

Atrial fibrillation in cardiac resynchronization therapy

Heart Rhythm O2, 2021
Patients with atrial fibrillation (AF) were largely excluded from the major clinical trials of cardiac resynchronization therapy (CRT), despite the presence of AF in up to 40% of patients receiving CRT in clinical practice.

Rate-dependency of action potential duration and refractoriness in isolated myocytes from the rabbit AV node and atrium [PDF]

, 2000
During atrial fibrillation, ventricular rate is determined by atrioventricular nodal (AVN) conduction, which in part is dependent upon the refractoriness of single AVN cells.

Comparison of the Efficacy and Safety Endpoints of Five Therapies for Atrial Fibrillation: A Network Meta-Analysis

Frontiers in Cardiovascular Medicine, 2022
IntroductionAtrial fibrillation (AF) is a prevalent arrhythmia that occurs in 2–4% of adults and poses a threat to human health. Thus, comparison of the efficacy and safety of therapies for AF is warranted.

Junctional ectopic tachycardia (JET)

Journal of Arrhythmia, 2020
Junctional ectopic tachycardia (JET) is a tachyarrhythmia arising from the atrioventricular node and His bundle area. Enhanced normal automaticity has been postulated as the mechanism of JET in the majority of patients.

Atrial fibrillation and heart failure: A contemporary review of current management approaches

Heart Rhythm O2, 2021
Atrial fibrillation (AF) and heart failure (HF) frequently coexist and complicate the course of treatment of each other. AF with rapid ventricular conduction can lead to tachycardia-mediated cardiomyopathy, which is a reversible cause of cardiomyopathy ...

Comparative aspects of the dual role of the human atrioventricular node [PDF]

, 1986
As well as transmitting the impulse from the atria to the ventric1es the atrioventricular node has two other important functions namely: (a) synchronisation of atrial and ventricular contractions by a varying delay; and (b) protection of the ventricles ...
