[The diagnostic value of pharmacologic double contrast and conventional barium meal of the stomach (author's transl)].

The authors compared the diagnostic accuracy of pharmacologic double contrast, conventional barium meal and oesophago-gastro-duodenoscopy of the stomach in 922 selected patients. The agreement rate between conventional investigation and endoscopy was 70.3%, while it was 83.

[Systolic time intervals: echocardiographic study of the right and left ventricle. (author's transl)].

Right and left ventricular systolic time intervals are measured in 40 cardiopathic subjects and compared with the respective values concerning 20 normal subjects. The results show a modification: a) of the values concerning the right ventricle in presence of pathology interesting this ventricle; b) of the values concerning the left ventricle in presence of pathology interesting this ventricle; c) of the values concerning both the ventricles in presence of left ventricular pathology which has, also, interested the right ventricle. The AA.

[Echo-phonomechanocardiographic relations of the systolic time intervals of the left ventricle (author's transl)].

15 normal subjects and 23 subjects with cardiac valve disease have been studied. All the subjects have undergone an echo-phonomechanocardiographic investigation with simultaneous recording of the tracings. The values of the systolic time intervals have been obtained from the echo-cardiographic tracings and compared with those obtained from the phonomechanocardiographic tracings evaluating the differences between them.
