摘要 心力衰竭是目前严重危害小儿生命健康的一大常见疾病,临床漏诊率及病死率较高。对于小儿心功能的准确、有效的评估对疾病的诊治、监测及预后判断具有重要的临床意义。Tei 指数是由日本学者提出的一种可以综合评价心室收缩及舒张功能的指标,定义为心室等容收缩间期与等容舒张间期之和与心室射血时间的比值。该指标不受心率及心室的几何构型等外界因素影响,具有测量方法简便、重复性强、无创等优点,其对于心室功能受损判定的敏感性高。在临床评价心功能,尤其是对小儿心功能的评估中,得到了越来越多的应用。该文就 Tei 指数的测量原理及测量方法、相关影响因素及儿科中的临床应用和进展等作一综述。 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.
