Syncope and paroxysmal atrioventricular block [PDF]

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 “cardiac syncope” is also ...

Reflex Atrioventricular Block [PDF]

Frontiers in Cardiovascular Medicine, 2020
Reflex atrioventricular block is well-recorded although it is considered rare. Recent data suggests that it is less rare than has been supposed. It has been shown to occur in both vasovagal and carotid sinus reflexes.

Unravelling Atrioventricular Block Risk in Inflammatory Diseases: Systemic Inflammation Acutely Delays Atrioventricular Conduction via a Cytokine‐Mediated Inhibition of Connexin43 Expression

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Recent data suggest that systemic inflammation can negatively affect atrioventricular conduction, regardless of acute cardiac injury.
