[Heart rate turbulence in patients with ventricular tachy arrhythmias of noncoronary genesis].

Aim: To assess parameters of heart rate turbulence in patients with ventricular extrasystoles (VES).

Material And Methods: Patients with VES during Holter ECG monitoring (n=65, age 1-17 years, 32 girls, 33 boys) including 3 with long QT syndrome, 4 with catecholaminergic ventricular tachycardia, 1 with arrhythmogenic right ventricular dysplasia, 4 with dilated cardiomyopathy, 2 with Brugada syndrome, 3 with Duchenne myopathy, and 48 with idiopathic VES. Parameters HRT onset and slope were calculated for 1678 VES.

[Prevalence of electrocardiographical signs of right ventricular arrhythmogenic dysplasia].

Unlabelled: Right ventricular arrhythmogenic dysplasia (RVAD) is a state with high risk of sudden death in young patients. Early diagnosis of RVAD can facilitate sudden death prevention.

Aim: To assess prevalence of electrocardiographical signs of RVAD among children with "idiopathic" tachyarrhythmias.
