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 ...

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 ...

Atrioventricular (AV) nodal reentrant tachycardia (AVNRT) is an irregular heart rhythm that can cause excessively fast heart rates. Though not usually serious, early diagnosis can help prevent severe ...

We reviewed randomized controlled trials, review articles and clinical practice guidelines to present a practical approach to the diagnosis and management of SVTs (Box 1). We focus on the most common ...

Supraventricular tachycardia is a term used to describe any heart rhythm that is greater than 100 beats per minute originating from above the AV node (the atrium). The term “SVT” can be confusing at ...

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 ...

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

Atrioventricular nodal reentrant tachycardia is the most common form of paroxysmal supraventricular tachycardia, or PSVT, in adults. AVNRT occurs when a reentrant circuit is present within the AV node ...
