Syncope and paroxysmal atrioventricular block
Journal of Arrhythmia, 2017 Current literature reveals three types of paroxysmal atrioventricular block (AVB) that can cause syncope:Intrinsic paroxysmal atrioventricular block is due to an intrinsic disease of the AV conduction system; this type of âcardiac syncopeâ is also ...

Prolonged PR interval, first-degree heart block and adverse cardiovascular outcomes: a systematic review and meta-analysis [PDF]
, 2016 Objective: First-degree atrioventricular block is frequently encountered in clinical practice and is generally considered a benign process. However, there is emerging evidence that prolonged PR interval may be associated with adverse outcomes. This study

Transient complete heart block following catheter ablation of a left lateral accessory pathway. [PDF]
, 2019 A 16-year-old female with symptomatic Wolff-Parkinson-White (WPW) syndrome underwent catheter ablation of a left-sided lateral accessory pathway. The accessory pathway was eliminated with the first ablation lesion; however, the patient immediately ...

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 ...

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.

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.
