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 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 کاملSlow pathway modification for atrioventricular node re-entrant tachycardia: fast junctional tachycardia predicts adverse prognosis.
OBJECTIVE To examine the cycle length of the junctional tachycardia often seen during successful slow pathway ablation for atrioventricular (AV) node re-entrant tachycardia, to determine whether shorter cycle lengths predict imminent atrioventricular block. DESIGN Retrospective analysis of consecutive patients undergoing slow pathway modification. Intracardiac recordings were analysed after d...
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...
