One hundred and eighty three male patients aged from 35 to 55 years were examined to study the heart rate variability and the QT dispersion at the metabolic syndrome complicated with cardiac arrhythmias. The diminution of the temporal pattern of heart rate variability, increase of the both sympathetic tone and sympathetic-vagal ratio were revealed in patients with supraventricular and ventricular rhythm disturbances. These changes were especially characteristic for patients with atrial fibrillation. QT dispersion was higher in patients with ventricular arrhythmias in comparison with other groups, although maximal corrected QT interval and its maximal dispersion was revealed in patients with combined cardiac arrhythmias (either ventricular and supraventricular arrhythmias).
