A first-degree atrioventricular node block occurs when conduction through the AV node is slowed, thereby delaying the time it takes for the action potential to travel from the sinoatrial node ...

A first-degree AV node block occurs when conduction through the AV node is slowed, thus delaying the time it takes for the action potential to travel from the SA node, through the AV node ...

In this report, 75% (43 of 57 patients) of patients with AV block caused by drugs had blocks at the level of the AV node. In addition, infranodal block was revealed in only 14% (eight of 57 ...

The level of AV block (AV-nodal or infranodal) was defined according to electrocardiographic characteristics. Results:The most frequent culprit medications were β-blockers followed by digoxin.

The presence of type I second-degree AV block with a narrow QRS complex is almost invariably localised in the AV node. One should remember that what appears to be narrow QRS type II block may be a ...
