Myocardial performance index formula
WebBackground: Tei index expresses the overall systolic and diastolic myocardial function in a single number. The use of tissue Doppler instead of conventional pulsed wave Doppler enables us to measure Tei index in a single scan. It also has many advantages for the assessment of myocardial function with coronary revascularization in IHD patients. WebJul 4, 2011 · INTRODUCTION. The left myocardial performance (Tei) index (MPI) is a simple and reproducible means of assessing adult global ventricular function 1, based on three cardiac time intervals, the isovolumetric contraction time (ICT), isovolumetric relaxation time (IRT) and ejection time (ET), according to the formula MPI = (ICT + IRT)/ET.ICT is …
