[ 1 ] - DOPPLER-DERIVED RIGHT VEN T RICU L AR MYOC ARD IAL PERFORMANCE IN DEX IN NEON ATES: N ORMAL VALUES

Doppler-derived myocardial performance index (MPI) , defined as the s um of isovolumetric contraction and relaxation durations divided by ejection time, is an easily measured and reproducible index that shows both systolic and diastolic myocardial function. The goal of this study was to define normal values of right ventricular MPI in neonates in the first 48 to 72 hours of life. Fifty-one...
