[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. emphasize the importance of the right and left ventricular systolic time intervals not only to separate pathology interesting the right ventricle from that interesting the left ventricle, but also, to evaluate the ventricular performance and the stage of evolution and extension of the cardiopathy.
