[Hypertrophic cardiomyopathies (author's transl)].

Because of their rapidly changing hemodynamic inconstancy depending on many, sometimes competing, processes, hypertrophic cardiomyopathies present a clinical picture extraordinary among the cardiac diseases, with severely altered diastolic compliance of the left ventricle and a functional stenosis in the obstructive forms. They are of increasing importance for the doctor in hospital or general practive, particularly because they are among the very few diseases in which the usual cardiac therapy with digitalis or else the administration of sympathomimetics is contraindicated.
