摘　　要：目的通过对瞬时加速度波强（W1）与Tei指数的相关性分析，探讨瞬时波强（W1）新技术的临床应用价值。方法应用Prosound α10彩色多普勒超声对66例正常人左右颈总动脉W1的强度（W1的最高点）与Tei指数的相关性进行分析。结果66例正常人左右颈总动脉W1（压力）之间呈正相关（P〈0．01）；左右颈总动脉W1（管径）之间呈正相关（P〈0．01）。左右颈总动脉W1（压力）与Tei指数呈负相关（P〈0.05）；左右颈总动脉W1（管径）与Tei指数呈负相关（P〈0．01）。左右颈总动脉W1（压力）均值与Tei指数呈负相关（P〈0．05）；左右颈总动脉W1（管径）均值与Tei指数呈负相关（P〈0．01）。结论W1与Tei指数负相关，可作为判断心脏收缩功能的指标。[ Objective To evalute the clinical application of the new technique of instantaneous wave intensity（WI） through the correlative analysis of instantaneous acceleration wave intensity（W1 ） and Tel index. Methods The correlation of the intensity of W1 （the apogee of W1 ） and Tel index of 66 healthy adults were analyzed by Prosound α10 color Doppler ultrasonograph. Results There were positive correlations in pressure and caliber between the common carotid arteries of both sides in 66 cases of healthy adults （P〈0. 01 ）. There were negative correlations respectively between the pressure of W1 of left and right common carotid arteries and Tei index （ P〈0. 05）,and there were the same in caliber （ P 〈0.01 ）, mean pressure （ P〈0. 05） and mean caliber （ P 〈0.01 ）. Conclusions W1 is negatively correlated with Tei index and can be an index in judging the systolic function.
