title: [Reliability of the ultrasonic study of the heart].
abstract: Based on a study of echograms from the heart structures the probabilities of receiving echosignals have been calculated. The probability to detect signals from the endocardium has been shown to be markedly higher than that from the pericardium. Because of great diffusive component of a scattered signal from the endocardium echosignals are reliably received during ultrasonic heart examination.
