Diastolic function of the left ventricular in athletes with small abnormalities of heart development

The purpose of our research was studying of cardiovascular system overexertion symptoms by dynamic of diastolic function of left ventricle during exercises of different power in athletes with small abnormalities of heart development. We surveyed 70 athletes aged 12-27 years. The diastolic function dynamics of left ventricular is showed in the work. The main indexes of myocardium relaxation disorders during diastole are defined. It is proved that in athletes with small abnormalities of heart development (mitral valve prolapse, open oval window) during submaximal physical loadings, signs of left ventricular diastolic dysfunction developed.
