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. The comparison has pointed out values nearly coincident, providing useful elements about the relations existing between the cardiac sounds and the moments of closure of the mitral and aortic valves. Moreover, the two techniques are considered useful and valid in the evaluation of the left ventricle performance by the systolic time intervals, especially when the recording is carried out simultaneously.
