The AV node has a long refractory period allowing it to “block” conduction to the His-purkinje system of the ventricles if there are excessive atrial depolarizations as in atrial fibrillation ...
Objective:To identify the frequency of atrioventricular (AV) conduction improvement after discontinuation of the culprit drug in patients with AV block. Background:AV blockers are considered as ...
Because the normal ventricular conduction system (His-Purkinje ... Because the electrical activation originates at or near the AV node, the P wave is frequently not seen; it can be buried within ...

Age-related decline in cardiac conduction system regeneration increases arrhythmia risk after heart attackNew research highlights postnatal regeneration limits and pathological remodeling of the cardiac conduction system after myocardial ... ventricular fibrillation, atrioventricular block, and ...
The impulse is then passed to another node within the heart – the atrioventricular node (AVN). This node is in the lower part of the right atrium.
Less than 5% of patients developed first-degree AV block or intraventricular conduction defect and the occurrence of side effects was not related to dose. [23] In our study, propafenone-related AV ...
