Aim. To study the role of disturbed autonomic regulation of the cardiovascular system information of the phenomenon of geliogeomagnetic sensitivity of patients with left ventricular ischemic dysfunction. Material and methods. 24-h synchroneous monitoring of ECG and electromagnetic situation was made in 11 patients (mean age 49.4+/-0.9 years) who had survived macrofocal myocardial infarction (MI) at least 6 months before and in 15 healthy volunteers. Results. Heart rhythm dispersion, correlation between variations of magnetic field vector component amplitudes and standard deviation of ECG R-R intervals duration in MI survivors were significantly less than in healthy subjects. High conjugacy of heart rhythm dispersion and mean value of R-R intervals (functions synchronization index) was characteristic only for the control group. A 3-week therapy with atenotol provided normalization of the disturbed correlations in 4 patients. Conclusion. Pathogenic geliogeotropic reactions in MI survivors develop because of intra- and inter-systemic desynchronisation of the functions mechanism of which is mediated by sympathicoadrenal activation and is correctable by beta1-adrenoblocker atenolol.
