[Characteristics of the sound symptomatology of the heart in functional cardiopathy].

Sixty persons with functional cardiopathy who had a systolic murmur were examined. The purpose of the study was the demonstration of the criteria for the positive diagnosis of a functional systolic murmur in this pathologic condition since hyperdiagnosis of valvular heart disease among these patients is a frequent occurrence. The auscultatory and phonocardiographic characteristics of the functional systolic murmur are described, a conclusion on the absence of any connection between this murmur and the valvular apparatus of the heart is drawn, an opinion on the mechanism of its formation is presented, and the data on the effect of beta-blocking agents on the systolic murmur (single dose and a course of treatment) are discussed.
