Changes of parameters of heart rate variability (HRV) in patients with supraventricular tachycardia (SVT) immediately after radiofrequency ablation (RFA) have been demonstrated earlier. However dynamics of HRV parameters after RFA has not been sufficiently studied. For elucidation of dynamics of HRV parameters in patients with SVT after RFA we conducted(More)
AIM To assess effect of radio frequency catheter ablation (RFCA) on heart rate variability (HRV) in patients with supraventricular tachyarrhythmias (SVT). METHODS Spectral analysis of HRV on 5-minute ECG strips was carried out in 19 patients with SVT before and 2 days after RFCA. RESULTS Both total and high frequency power significantly decreased(More)
From January 1983 to May 1992 a total of 40 patients with a tachysystolic type of atrial flutter (AF) refractory to preventive antiarrhythmic therapy were examined and operated on. The obligatory stage of a preoperative examination was invasive phonoelectrocardiography. The effects of "entrainment" and adaptation of refractory periods of various portions of(More)
