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 ...

This would even include sinus tachycardia with a right or left bundle branch block, atrial fibrillation/flutter with a right or left bundle branch block or AVNRT with a right or left bundle branch ...

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 ...

Twenty patients (eight males, age 46.5 ± 12.5 years) with electrocardiogram (ECG) documentation of supraventricular tachycardia and AVNRT diagnosed by cardiac electrophysiology study were studied.

Atrioventricular nodal re-entrant tachycardia (AVNRT) can trigger atrial fibrillation (AF), but the incidence of AVNRT as a cause of AF is unclear. Identification of patients with AVNRT could ...

Figure 18B shows the 12-lead ECG of the entrainment tracing of Figure 18A. The QRS morphology in all 12-lead ECGs during entrainment is identical to that of pacing in the absence of tachycardia as ...
