Myocardial performance index, also known as Tei index was introduced in 1995 by Tei et al ¹. It gives information about global ventricular function ².

It is calculated by dividing sum of isovolumetric contraction time (IVCT) and isovolumetric relaxation time (IVRT) with ejection time (ET), i.e. MPI = (IVCT + IVRT) / ET
