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 ... with irregular wide QRS AV = atrioventricular.

The atrioventricular, or AV, node is the second key area of the heart’s electrical wiring. The atrioventricular node takes information about how fast the heart is beating from the sinoatrial ...

Junctional bradycardia occurs when the electrical impulse to start the heartbeat begins in the atrioventricular (AV) node rather than in the SA node. The AV node is a structure at the bottom of ...

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.
