The normal age variation in left ventricular parameters in males (left) and females (right). Solid lines represent rational polynomial curve fit and dashed lines the 95% prediction intervals of this fit. Reference values are listed in Table 2. BSA = body surface area, ESV = end-systolic volume, SV = stroke volume, EF = ejection fraction.
