Familial Occurrence of Atrioventricular Nodal Reentrant Tachycardia in a Mother and Her Son
نویسندگان
چکیده
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, who were symptomatic and successfully treated with radiofrequency catheter ablation of slow pathway.

Letter by Denham et al Regarding Article, "Familial Occurrence of Atrioventricular Nodal Reentrant Tachycardia".
To the Editor: Michowitz et al present an interesting study on the prevalence of familial atrioventricular nodal reentrant tachycardia (AVNRT). They report a prevalence of 127 out of 10 000 of familial AVNRT with a likely autosomal dominant pattern of inheritance (with incomplete penetrance). A potentially important question is whether all the observed cases represent “pure” familial AVNRT or w...
متن کاملFamilial Occurrence of Atrioventricular Nodal Reentrant Tachycardia.
BACKGROUND Atrioventricular nodal reentrant tachycardia (AVNRT) is considered a sporadic disease occurring in ≈22.5 cases per 10 000 in the general population. We define the prevalence and characteristics of familial AVNRT among patients who underwent radiofrequency ablation. METHODS AND RESULTS Ablation reports of all patients with familial AVNRT (at least 2 first-degree family members) who ...
متن کاملTwo unusual cases of coincident atrioventricular nodal reentrant tachycardia and ventricular tachycardia.
The simultaneous occurrence of narrow and wide QRS complex tachycardias was observed in 2 patients evaluated at our electrophysiological centers. Electrophysiological testing revealed the coexistence of two types of arrhythmia (atrioventricular nodal reentrant tachycardia and verapamil-sensitive left ventricular tachycardia) in one patient and of three types of arrhythmia (atrioventricular noda...

AIMS The aim of this study was to compare cardiac autonomic regulation in patients with a history of paroxysmal supraventricular tachyarrhythmias, such as atrioventricular nodal reentrant tachycardia and atrioventricular reentrant tachycardia, and healthy controls. METHODS AND RESULTS Seventeen patients with paroxysmal atrioventricular nodal reentrant tachycardia (atrioventricular nodal reent...
متن کاملFast pathway ablation in patients with common atrioventricular nodal reentrant tachycardia and prolonged PR interval during sinus rhythm.
AIMS This study aimed to clarify the safety and efficacy of selective fast pathway ablation in patients with atrioventricular nodal reentrant tachycardia and a prolonged PR interval during sinus rhythm. Such patients have been reported to have an increased incidence of complete atrioventricular block. METHODS AND RESULTS In this study, the earliest retrograde atrial activation during atrioven...
