INTRODUCTION No prior studies have systematically investigated the diagnostic value of cycle length (CL) variability in differentiating the mechanism of paroxysmal supraventricular tachycardia (PSVT). METHODS AND RESULTS We studied 173 consecutive patients with PSVT; 86 typical atrioventricular nodal reentrant tachycardia (AVNRT), 11 atypical AVNRT, 47 orthodromic reciprocating tachycardia (O...
Introduction Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common regular supraventricular arrhythmia. It typically presents with rapid and regular palpitations of abrupt onset in young adults, with a female preponderance. In patients without structural heart disease, AVNRT is largely considered to have a benign course and is rarely associated with disabling symptoms, such as...
BACKGROUND Slow-pathway ablation or modification eliminates typical atrioventricular nodal re-entrant tachycardia (AVNRT) but with a 1% risk of AV block. We report our experience from a series of consecutive patients with typical AVNRT who were ablated in our unit. METHODS Consecutive patients (n=227), aged 22 to 56 years, 172 women, with slow-fast AVNRT underwent slow-pathway ablation. Mappi...
Purpose Atrioventricular nodal reentry tachycardia (AVNRT) is less common in pediatric patients than in adult patients. Thus, data for pediatric AVNRT patients are insufficient. Hence, we aimed to analyze the patient characteristics, treatment, and any recurrences in pediatric AVNRT patients. Methods We reviewed the records of 50 pediatric AVNRT patients who had undergone radiofrequency cathe...
INTRODUCTION Published reports of radiofrequency ablation of atypical atrioventricular nodal reentrant tachycardia (AVNRT) have been limited. We present our experience in 10 consecutive patients with atypical AVNRT who underwent radiofrequency ablation of the "slow" AV nodal pathway. METHODS AND RESULTS There were 9 females and 1 male; their mean age was 44 +/- 19 years (+/- SD). The mean AVN...
Atrioventricular nodal reentrant tachycardia (AVNRT), caused by a reentry circuit involving fast and slow atrioventricular nodal pathways, is one of the most common types of paroxysmal supraventricular tachycardias. While familial Wolff-Parkinson-White syndrome has been well recognized, familial AVNRT has been rarely reported. We report a familial occurrence of AVNRT in a mother and her son, wh...
BACKGROUND Because of its low prevalence, data on atypical atrioventricular nodal reentrant tachycardia (AVNRT) are scarce, and the optimal ablation method has not been established. Our study aimed at assessing the efficacy and safety of conventional slow pathway ablation, as applied for typical cases, in atypical AVNRT. METHODS We studied 2079 patients with AVNRT subjected to slow pathway ab...
and congratulate them on their publication. There are some points in the aim of their study, method, and results, however, which I believe require further clarification. 1. The Introduction states that " Thus far, the most conventional marker and end point for successful radiofrequency (RF) ablation has been considered the loss of the inducibility of atrioventricular nodal reentrant tachycardia...
BACKGROUND To evaluate the choice and utility of pacing maneuvers in the electrophysiology (EP) laboratory in establishing supraventricular tachycardia (SVT) mechanism. METHODS We retrospectively examined a cohort of 160 consecutive patients with SVT presenting for invasive EP evaluation to a single center with 8 electrophysiologists. We analyzed the utility of the two most commonly used paci...
OBJECTIVE The aim of this retrospective study was to investigate the association of atrioventricular nodal reentrant tachycardia (AVNRT) with other forms of arrhythmia in individual patients and its consequences for treatment. SUBJECTS AND METHODS This study comprised 493 consecutive patients aged 16-88 years (296 women and 197 men) who were diagnosed with a form of AVNRT via a standard 4-cat...
