Values are averages ± SE for each measure. CO, cardiac output, Diameter;d, diameter at diastole, Diameter;s, diameter at systole; EF, ejection fraction; FS, fractional shortening; LV Mass, left ventricular mass; LV Vol;d, left ventricular volume at diastole; LV Vol;s, left ventricular volume at systole; SV, stroke volume; V;d, volume at diastole; V;s, volume at systole.
