Coexistent Types of Atrioventricular Nodal Re-Entrant Tachycardia
T he mechanism of atrioventricular nodal re-entrant tachy-cardia (AVNRT) remains elusive. Both anatomic and functional models have been proposed. There has been elec-trophysiological evidence that the right and left inferior extensions of the human AV node and the atrionodal inputs they facilitate, which have been identified histologically, might provide the anatomic substrate for the slow path...
متن کاملCoexistent Types of Atrioventricular Nodal Re-Entrant Tachycardia: Implications for the Tachycardia Circuit.
BACKGROUND There is evidence that atypical fast-slow and typical atrioventricular nodal re-entrant tachycardia (AVNRT) do not use the same limb for fast conduction, but no data exist on patients who have presented with both typical and atypical forms of this tachycardia. We compared conduction intervals during typical and atypical AVNRT that occurred in the same patient. METHODS AND RESULTS I...
متن کاملIsoprenaline and inducibility of atrioventricular nodal re-entrant tachycardia.
OBJECTIVES To examine the effect of isoprenaline on slow and fast pathway properties and tachycardia initiation. DESIGN Consecutive patients, prospective study. SETTING Referral centre for cardiology, academic hospital. PATIENTS 24 patients suffering from common type atrioventricular nodal reentrant tachycardia (AVNRT). INTERVENTIONS Programmed electrical stimulation and radiofrequency ...
متن کاملClassification of electrophysiological types of atrioventricular nodal re-entrant tachycardia: a reappraisal.
Sequence of retrograde atrial activation is not a reliable criterion for the classification of atrioventricular nodal re-entrant tachycardia (AVNRT) into typical and atypical types. The conventional concept of a lower common pathway is not supported by current evidence and does not represent a reliable or reproducible criterion. The distinction between 'fast-slow' and 'slow-slow' forms is not u...
متن کاملElectrophysiological predictors of propafenone efficacy in prevention of atrioventricular nodal re-entrant and atrioventricular re-entrant tachycardia
AIM To assess the efficacy of propafenone in prevention of atrioventricular nodal reentrant tachycardia (AVNRT) and orthodromic atrioventricular tachycardia (AVRT) based on the clinical results of arrhythmia recurrence and find the electrophysiological predictor of propafenone effectiveness. METHODS This retrospective study included 44 participants in a 12-month period, who were divided in tw...
