AVRT = atrioventricular reciprocating tachycardia ... Other abbreviations as in Figure 1. Entrainment of AVNRT. Voltage maps (purple represents the leading edge of excitation and red represents ...
AVNRT occurs when a reentrant circuit is present within the AV node itself. In this situation, there are two separate conduction pathways within the AV node instead of just one (present in about 5 ...
AV tachyarrhythmias consist of AVNRT, AVRT, nonparoxysmal junctional tachycardia, and junctional ectopic tachycardia. [15] Supraventricular arrhythmias may occur in the pre- and post-MI setting.
If an action potential is able to traverse the accessory pathway and then return retrograde through the AV node ― or vice versa ― a reentrant circuit can be created, resulting in AVRT.
