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 ...

This is a narrow QRS complex tachycardia with a very fast heart rate (about 250 beats per minute). It is quite difficult to indentify any P wave activity to determine the exact etiology. Most commonly ...

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 ...

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 ...
