atrioventricular nodal reentry

atrioventricular nodal reentry
AV nodal reentry an arrhythmia-causing mechanism in which two opposing pathways are established within the atrioventricular node (longitudinal dissociation); the anterograde pathway, which is usually slower, activates the ventricles and the retrograde pathway, which is usually faster, activaties the atria. This mechanism is responsible for approximately half of symptomatic paroxysmal supraventricular tachycardias.
