Use of the variation pulsimetry in the evaluation of diurnal dynamics of cardiac rhythm in patients with ischemic heart disease and functional disorders of the cardiovascular system

The results of employing the method of variation pulsimetry and dynamic electrocardiography in 30 patients are discussed. Analysis of the circadian dynamics of the statistical characteristics of cardiac rhythm showed that the activity of the sympathetic part of the vegetative nervous system was higher in patients with ischemic heart disease than in those with functional disorders. Disbalance of neurohumoral control of cardiac rhythm in various types of arrhythmias was disclosed.
