This is sometimes termed “dual AV nodal physiology.” One pathway is slower and has a short refractory period, while the other is faster and has a long refractory period. Normal conduction ...

Atrioventricular nodal reentry tachycardia (AVNRT) occurs when there is "dual AV nodal physiology" or a "dual AV node." This means there is one pathway that conducts slowly within the AV node and ...

Atrioventricular nodal reentrant tachycardia (AVNRT) is a rapid, irregular heartbeat that starts suddenly and without warning and stops just as abruptly. It is a common type of what's called ...

To test the electrophysiological effect of ablating the potential site, programmed electrical stimulation that had reproducibly demonstrated dual-AV nodal physiology or induced AVNRT was performed ...

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.

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) of them. Thus, one could suggest that if the ...
