Abstract
The study was performed to identify the possibility of radionuclide tomo-ventriculorgraphy (RTVG) in the evaluation of mechanical dyssynchrony of myocardium intracardiac hemodynamics in ventricular arrhythmias in children. We examined 76 children with ventricular arrhythmias (average age 13.2 ± 3.7 years), including 16 patients before and after radiofrequency ablation procedures. All patients underwent RTVG. In patients with ventricular arrhythmias we identified zones of asynchronous contraction of the myocardium (ACM) and reduction hemodynamics with increasing intraventricular dyssynchrony. After radiofrequency ablation (RFA) there was a significant decrease in the number of ACM, improvement of contractile function and decrease of intraventricular dyssynchrony of the right ventricle.
