Abstract:
Currently,heart failure is one common disease causing serious damage to children's health and life which has high missed diagnosis rate and mortality.Accurate and effective evaluation of pediatric cardiac function is of great importance in the treatment,surveillance and prognosis of disease.Tei index was first presen-ted by Japanese scholars as a new comprehensive indicator of global (combined systolic and diastolic)myocar-dial function.It was defined as a ratio between the sum of isovolumic times (ICT and IRT)and ejection time (ET).This index can be measured by a simple,reproducible and non-invasive method regardless of changes in the heart rate or ventricular shape and other external factors.The sensitivity for ventricular dysfunction could be high.Tei index has been used more and more often in the clinical evaluation of cardiac function especially in children.This paper reviews the measurement methods,related factors and pediatric clinical application progress of Tei index.
