Dayly profile microalternations of ECG-signals according to dispersion mapping

Abstract

This report presents preliminary results of the analysis of the circadian monitoring factors of dispersion mapping (DM). Analyzed daily ECG monitoring in healthy individuals in a free life activity (I group), the data obtained during the research program "Mars-500" in 6 healthy men (2 group), in patients with hypertension (3 group) and IHD with episode of ventricular arrhythmia I-II class on Launu (4 group). For analysis areas by duration in 15-20 minutes from each hour «were cut". Study of the circadian factors of ECG-signal microalternations is a new diagnostic approach to the analysis of electrophisiological status and diagnostic test of the revealing of the myocardium lesions. DM method can be used to obtain new data on electrophysiological features of the myocardium during the day and the diagnosis of myocardium electrical heterogenicity.
