[Ultrasound evaluation of heart disease, with special reference to congenital and acquired lesions (author's transl)].

Time position monitoring of numerous cardiac structures can be obtained by single element echocardiography with high time resolution. This method offers an important way to measure cardiac dimensions and to prove the anatomical relation different cardiac structures. Technological problems are briefly discussed and normal values are given. Cardiac lesions diagnosed by echocardiography are reviewed.
