Background: To establish physiological values of systolic and diastolic indexes in healthy term newborns by tissue Doppler imaging (TDI) Objective: To measure the ventricular and septal myocardial velocities using tissue Doppler imaging in the first 72 h of life in neonates. Material and Methods: Left and right ventricular peak systolic (Sm), early diastolic (Em) and late diastolic (Am) myocardial velocities were measured at three different sites (Left ventricle, Inter ventricular septum and Right ventricle) using tissue Doppler imaging along with standard echocardiography. TEI index was also calculated. Results: Forty normal term neonates were recruited. The mean velocity of the myocardial motility (Em, Am and Sm waves) obtained from the septum were significantly lower than those from the RV or LV, and the RV had significantly greater velocities than the LV and Septal during systole and late diastole ( p<0.05). Conclusion: TDI is a non-invasive, feasible and an effective method for the evaluation of the cardiac function and myocardial velocities through the cardiac cycle in the neonate.
