Clinical and electrophysiological characteristics in patients with atrioventricular reentrant and atrioventricular nodal reentrant tachycardia

Abstract

Patients with AVRT have a lower mean age at arrhythmia symptom onset compared with those with AVNRT and have fewer associated cardiac abnormalities. Clinical presentation is quite similar as well as their outcome after ablation. A correct diagnosis by standard ECG is more frequent in AVNRT.

New insights into the clinical signs of supraventricular tachycardia: The “sign of lace‐tying”

“…We observed a similar set of symptoms and associated frequencies during tachycardia compared to other series (Bottoni et al., ; Wood, Drew, & Scheinman, ). Syncope occurred in 14.9% of patients with AVNRT and 20.8% with AVRT.…”

“…We observed higher frequencies of dyspnea, fatigue and chest pains or discomforts in our cohort compared with other series (Bottoni et al., ; Wood et al., ), possibly due to the prospective and extensive nature of our study.…”

“…Table shows the demographic and clinical characteristics of patients. As for other series, the mean age at diagnosis of SVT was lower for AVRT than for AVNRT(Bottoni et al., ). The mean age during treatment for SVT was 51 ± 18 years for AVNRT, 34 ± 20 years for AVRT and 52 ± 13 years for A.Tach.…”

Combined Evaluation of Bedside Clinical Variables and the Electrocardiogram for the Differential Diagnosis of Paroxysmal Atrioventricular Reciprocating Tachycardias in Patients Without Pre-Excitation

“…Previous studies have shown the univariate significant associations of age at onset of first arrhythmic event (1,2,8,9), sex prevalence (1)(2)(3)(4)9), and the presence of regular palpitations in the neck during tachycardia episodes (4,16,17) with the major mechanisms of paroxysmal, regular supraventricular tachycardias. Their biological plausibility has been discussed in detail elsewhere (9,16 -19).…”

Sustained Slow Pathway Conduction: Superior to Dual Atrioventricular Node Physiology in Young Patients with Atrioventricular Nodal Reentry Tachycardia?

“…Children with AVNRT demonstrate dual AV node physiology (DAVNP) less commonly than adults, and slow pathway modification results in greater effects on fast pathway refractoriness 3 . Furthermore, children frequently require isoproterenol for induction of AVNRT, while 62–94% of adults are inducible in the baseline state 4,5 . Finally, the smaller size of the heart, and particularly the region of Koch's triangle, necessitates the placement of lesions in closer proximity to the compact AV node when performing slow pathway modification 6 .…”
