title: [Echocardiographic calculation of left ventricle ejection volume. 2) Proposal of a new equation].
abstract: A new formula is proposed to calculate left ventricular ejection volume. It has been originated directly from Yeh equation, introducing two important factors: 1) left ventricular and diastolic diameter 2) ejection time adjusted according to heart rate. This new formula prove to give satisfactory results both as to stroke volume and cardiac output, thus allowing its possible clinical application.
