| Summary: | Heart rhythm disturbances structure and time domain peculiarities of heart rate variability are studied at 77 patients having ventricular preexcitation syndrome and phenomenon. Among the heart arrhythmias induced during the electrophysiologic study reciprocal orthodromic tachicardia, atrial fibrillation and combination of these arrhythmias prevail.Reliable decrease of heart rate variability values at syndrome in comparison with the ones at phenomenon determined. These data mean that vagal impact at heart rate regulation is decreased, thus leading to sympathic mechanisms predominance and, probably, to the sustained electrical instability of myocardium. |
