摘　　要：目的对比观察组织多普勒与脉冲多普勒两种方法测量左室Tei指数的一致性,探讨Tei指数在评价高血压患者左心功能的应用价值。方法对184例高血压病患者和78例健康体检者,分别采用组织多普勒与脉冲多普勒超声心动图测量左心功能Tei指数,分析两种超声心动图方法获得的左心室Tei指数的相关性。对高血压组按血压分级,并将高血压组各级的Tei指数及其他参数与正常对照组的数据进行比较。结果组织多普勒超声心动图测量Tei指数为(0.61±0.25),脉冲多普勒超声心动图测量Tei指数为(0.63±0.26),两者具有良好的相关性(r=0.81,P<0.01);高血压组各级的Tei指数与正常对照组相比存在显著差异(P<0.05或P<0.01)。结论与脉冲多普勒一样,组织多普勒也是获得左室功能指标——Tei指数的一种简单可靠超声心动图方法;Tei指数在各级高血压患者左心室功能评价中具有一定的临床应用价值。Objective The study is to evaluate the results of two methods i. e, measuring the Tei index by pulse Doppler echcariogrphy and tissue Doppler imaging（TDI method） and to investigate the clinical value of the Tei index in assession of Hypertension＇ s ventricular function. Methods One hundred and eighty four patients with hypertension and 78 healthy adults as the control subjects were enrolled in the study. The Tei Indexes were obtained respectively by pulse Doppler and tissue Doppler e- chocardiography method. Patients with hypertension were divided into three grade according to the hypertensive diagnostic criteria of WHO in 1999. This essay the results of Tei Indexes and other pa- rameters of the each grade in the was compared hypertensive group with the data obtained from the normal control group. Results The value of the Tei index by tissue Doppler was （0.61 ± 0.25） and the Tei index by pulse Doppler was （0.63 ± 0.26）. They were significantly related （ r = 0.81, P〈 0.01）. There was significance difference in the Tel index between each garde in hypertensive group and the normal control group （P〈0.05 or P〈0.01）. Conclusion The Tel Index obtained by tissue Doppler echocardiography is a simple helpful index for evaluation cardiac dysfunction as same as that by Doppler echocardiography.
