63 patients with ventricular extrasystoles was included in the study. 29 mean, 34 wemen. Mean age 29 – 63 year. Inclusion criterions into study was registered ventricular extrasystoli by 12 lead ECG, >4000 es/24h on Holther monitoring. In 16 patient electrophysiological study (EP) following radiofrequency ablation (RF) was performed. In 21 patients coronaroangiography was performed, no evidence of ischemic heart disease (IHD) was found. We exclude all patients with evidence of organic heart diseases, atrial arrhythmias and QT segment changes. 12 patients with no evidence of arrhythmia formed control group. In all patients Echocardiography with tissue doppler and synchronized myocardial quantitative gated SPECT was performed using 99Tc-pyrophospate using AnyScan Multimodality Imaging System. In RF ablation group myocardial quantitative gated SPECT was performed also 3 monts after procedure.
