Anatomic-electrophysiological correlations concerning the pathways for atrioventricular conduction. [PDF]

, 2001
The remarkable success of radiofrequency ablation in recent decades in curing atrioventricular nodal reentrant tachycardias has intensified efforts to provide a solid theoretical basis for understanding the mechanisms of atrioventricular transmission ...

A case of atrial fibrillation complicated by complete atrioventricular block

SAGE Open Medical Case Reports, 2023
Atrial fibrillation and complete atrioventricular block are two well-established arrhythmias that can share common aetiologies and risk factors. Although the two arrhythmias can co-exist, only a limited number of cases of atrial fibrillation complicated ...

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.

Development of a sheep model of atrioventricular block for the application of novel therapies.

PLoS ONE, 2020
INTRODUCTION:Sheep have been adopted as a pre-clinical large animal for scientific research as they are good models of cardiac anatomy and physiology, and allow for investigation of pathophysiological processes which occur in the large mammalian heart ...

A curious alliance: Sinus nodal dysfunction precipitating atrioventricular block

Journal of Arrhythmia, 2014
An elderly woman presented with recurrent syncope. Sinus bradycardia and sinoatrial block were seen on the electrocardiogram; however, PR interval prolongation after sinus pauses suggested atrioventricular conduction system disease.

Evidence that conflict regarding size of haemodynamic response to interventricular delay optimization of cardiac resynchronization therapy may arise from differences in how atrioventricular delay is kept constant. [PDF]

, 2014
Aims: Whether adjusting interventricular (VV) delay changes haemodynamic efficacy of cardiac resynchronization therapy (CRT) is controversial, with conflicting results.

Cesarean section under spinal anesthesia in acquired complete atrioventricular block without a pacemaker: A case report

Clinical Case Reports, 2019
Pregnancy with complete atrioventricular block is rare, and its perioperative management is controversial. We successfully managed cesarean section in a pregnancy with acquired complete atrioventricular block under spinal anesthesia without a pacemaker ...

Dopamine and epinephrine for managing complete atrioventricular block due to nonreperfused acute inferior wall myocardial infarction in a rural hospital: A case report

SAGE Open Medical Case Reports, 2021
Inferior wall myocardial infarction occurs in approximately 50% of all myocardial infarctions. The most common conduction disorder of this disease is complete atrioventricular block. Immediate attention must be given to the myocardial infarction patients
