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

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 quie...

"doppler-derived right ventricular myocardial performance index in neonates: normal values "

doppler-derived myocardial performance index (mpi), defined as the sum 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 (rv) mpi in neonates in the first 48 to 72 hours of life. fifty-one q...

Doppler-Derived Myocardial Performance Index in Healthy Children in Shiraz

Background: Assessment of myocardial function is essential in heart disease, but in regard to systolic and diastolic functions such evaluation has limitation. Ejection fraction is difficult to assess in abnormally-shaped ventricles, and diastolic inflow velocity pattern may be fused because of tachycardia. Objective: A myocardial performance index (MPI) or Tei index has been developed for adult...

Principal component analysis (PCA) is one of the most valuable results oriented techniques of applied linear algebra. PCA is used abundantly in all forms of analysis from neuroscience to computer graphics because it is a simple, non-parametric method of extracting relevant information from confusing data sets. Extracting or decoding this information or feature from ECG signal has been found ver...
