The atrioventricular node (AVN) has mystified generations of ... providing further insight into basic mechanisms involved in AV conduction. Additionally, procurement of explanted human hearts ...

and conduction could be delivered within this region altering AVJ pacemaker properties, possibly allowing it to drive conduction in the absence of a functioning SA nodal pacemaker. The role of the ...

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, and to ...

A premature atrial contraction (PAC) occurs when a focus in the atrium (not the SA node), generates an action potential before the next scheduled SA node action potential. When this occurs prior ...
