Atrioventricular nodal reentrant tachycardia is the most common form ... pathway with the long refractory period. If a premature atrial contraction, or PAC, or less commonly a premature ...

resulting in the tachycardia. Unlike atrial fibrillation and atrial flutter, AVNRT does not have any thromboembolic risk and is considered a relatively benign arrhythmia. Diagnosis is made on the ...

One significant area of research has been the development of novel diagnostic techniques to differentiate AVNRT from other similar conditions, such as atrial tachycardia (AT) and orthodromic ...

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 ...

Atrial flutter and fibrillation are especially ... or atrioventricular nodal re-entry tachycardia (AVNRT). Tachycardias, which respond to vagal maneuvers or other cholinergic agents like adenosine ...

One can examine the initiation and termination of tachycardia for clues as to its mechanism. In addition, information can be gleaned from irregularities (e.g., premature atrial contractions [PACs ...
