[A new approach to the left ventricular ejection time by systolic time intervals measurement with carotid arterial Doppler. Statistical study of correlation in one hundred and thirteen cases (author's transl)]. / Nouvelle approche de la fonction ventriculaire gauche par mesure d'intervalles de temps systoliques au Doppler carotidien. Etude statistique des corrélations à propos de cent treize cas.

The authors have determined systolic time intervals with carotid arterial Doppler system in a group of 113 healthy subjects. These systolic time intervals, were independent of age but strongly influenced by heart rate, and highly significant correlated with phonocardiographic and carotid arterial pulse tracings, according to the method described by Weissler. However Doppler index, no significantly correlated with heart rate, seems to us a better assessment of left ventricular performance than Weissler index. New reports on the hemodynamic determinants in healthy subjects and in patient with chronic heart failure are necessary.
