Background Different subforms of AV nodal reentrant tachycardia (AVNRT) have been
described (“Slow/Fast”,“Slow/Slow” and “Fast/Slow”). Our aim is to improve definition of …

The conduction time over the lower common pathway (LCP) in AVNRT can be assessed by
subtracting the HA‐interval during tachycardia (HAt) from that during ventricular pacing at …

Aims This study aimed at assessing the prevalence, electrophysiologic characteristics, and
mechanism of atypical atrioventricular nodal reentrant tachycardia (AVNRT). Methods and …

Objectives. This study sought to define the electrophysiologic and electrocardiographic
characteristics of fast–slow atrioventricular nodal reentrant tachycardia (AVNRT) …

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 …

Aims It was the purpose of this study to determine the incidence of more than two AV nodal
pathways in patients with AVNRT. Methods and results In 78 consecutive patients with AV …

BACKGROUND Residual slow pathway conduction in the form of persistent jump in the
atrioventricular (AV) conduction time or atrial echo beats is a common finding after …

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 …

Electrogram in AVNRT. Introduction: The purpose of this study was to determine the
predictors of successful ablation versus modification sites of the slow pathway in patients …

Background The tachycardia circuit in the fast-slow form of atrioventricular nodal reentrant
tachycardia (FS-AVNRT) has not been convincingly defined. Methods and Results To define …
