Three methods of breathing retraining (guided breathing retraining, guided breathing retraining with physiologic monitoring of thoracic and abdominal movement plus peripheral temperature, and guided breathing retraining with physiologic monitoring of thoracic and abdominal movement, peripheral temperature and end-tidal carbon dioxide) were compared with a no-treatment control group to determine the effectiveness of breathing retraining on modifying respiratory physiology and reducing functional cardiac symptoms in subjects with signs associated with hyperventilation syndrome. Of 41 subjects studied, 16 were diagnosed with mitral valve prolapse. Results demonstrated that all 3 methods of breathing retraining were equally effective in modifying respiratory physiology and reducing the frequency of functional cardiac symptoms. Results determined that respiratory rate and subject's perception that training had generalized were the best predictors of treatment success. Furthermore, it was found that subjects with mitral valve prolapse responded as well to treatment as did those without prolapse.

One hundred and sixty-six young military man with mitral valve prolapse (MVP) aged 19.2+/-0.8 years were examined. Complex system approach to health status was applied to study clinico-functional features of this condition in young military men. The study found that clinico-functional manifestations of MVP in young military men reflected a multifocal character of dysadaptation during the first stages of military service. Conditions of professional military activity potentiate permanent progress of crisp prolapse as well as the severity of mitral regurgitation, structural and functional myocardial alterations, and myocardial electric instability increasing in the presence of abnormal cardiac chords under the influence of a prominent vegetative dysfunction. The reserve of the cardiorespiratory system and the entire organism in military men with MVP was lowered. The study registered inadequate hemodynamic responses to functional orthostatic test and physical load test, typical for hyperventilation syndrome.
