[Recommendations regarding the standardization in m-mode- and two-dimensional echocargiography in the U.S.A. (author's transl)].

After a long discussion a standardization of quantitative measurements is m-mode echocardiography as well as standardization for displays of two-dimensional echocardiograms in the long and short axis views of the left ventricle was agreed upon in the U.S.A. in 1978. It seems to be reasonable to follow the recommendations in Germany also in order to have more uniformity in echocardiographic diagnosis. Standardization would help for the overall understanding of data between laboratories.
