[Primary idiopathic myocardiopathies]

Forty eight cases with primary idiopathic myocardiopathies were diagnosed in clinical conditions for a period of 2 years. Among the patients, being mainly young, at the age of 17-20--hypertrophic myocardiopathies predominated (44 cases), 27 of them were obstructive forms. Modern investigation methods were used in making the diagnosis of the cases, including cardiac probe with angio--and ventriculography, isotope gamma cardiographic, echocard ographic investigations as well as pharmacodynamic follow up of murmur findings with alfa beta blockers. Pseudoinfarction ECG images in young people, presence of systolic murmur of expulsion with p.m. at B. Erb and X-ray data for symmetric or asymmetric hypertrophy of the heart were the indicating sings for the diagnosis. The presence and recording of expulsion murmurs is stressed upon in making the diagnosis of those diseases which after alfa and beta blockers alter their intensity and character, the infarction-like ECG and especially the significance of echocardiography.
