AССENTS PHYSIOLOGY OF CARDIAC ACTIVITY DURING PHYSICAL EXERTION
For the successful implementation of physical activity requires some adaptation and adjustment of cardiac activity meets the prescribed load ability of the heart to meet them. For early detection of cardiac abnormalities, rationalizing the load on the heart, early prevention of violations will require a comprehensive information on the contractility of the heart, the nature of the work of AV connection, vegetative state and electrolyte balance in the body. Evaluation of adaptive rearrangements of cardiac activity and its correction can extend the life of active sport athlete.
