Determinants and Regression Equations for the Calculation of Scores of Left Ventricular Tissue Doppler Longitudinal Indexes in a Healthy Italian Pediatric Population
Table 4
Coefficients for regression equations relating left ventricular longitudinal indexes and age. For each index, application of the corresponding third-grade equation provides the expected logarithmic value according to age. In a patient with given age, this allows calculation of the score that corresponds to the observed value of the index in that patient (see text).
