Age-related involution of the sympathetic nervous system, sudden cardiac death and features of diagnosis of myocardial

Neurological nature of major cardiac diseases is attributed to elevated social tension. The established phenomena of early age involution of the sympathetic part of the vegetative nervous system due to Cannon's law make it possible to study the mechanism of sudden cardiac death and to search for diagnostic methods for its prevention. One of such methods is time-frequency spectral analysis of the heart rate variability at the early phases of orthostatic tests. The radionuclide diagnostic method has revealed new data on correlation between blood capillaries and sympathetic nervous plexus under myocardial infarction.
