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 improve ...

In this case, we describe a case of atypical slow-slow AVNRT in a patient with dextrocardia and an unusual His bundle position in the low posterior septum of the morphologic right atrium. The His ...

AVNRT is due to a congenital abnormality within the AV node that allows for a re-entrant tachycardia. In those susceptible to AVNRT, two conduction pathways exist within the AV node. One pathway ...

This is a narrow-complex QRS rhythm which is quite fast. Looking closely at the last part of the QRS complex in leads V1 and V2, P waves can be seen. This is considered a "short RP tachycardia" and is ...

A 75-year-old woman with dextrocardia, situs inversus, and subpulmonic outflow obstruction presented with recurrent supraventricular tachycardia (SVT). This SVT was easily inducible during ...
