[Adaptation of the myocardium to psychoemotional stress in patients with myocardial infarction and painless ischemia].

To assess features of heart adaptation to psychoemotional stress in patients with myocardial infarction (MI), we studied contractile and pump functions of the left ventricle in conditions of modelled informational stress. A total of 36 MI patients were examined using informational stress, echocardiography, electrocardiography, impedance plethysmography. We established variants of biological rhythms of the heart in MI patients with painless myocardial ischemia of psychogenic origin.
