Abstract:
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 Tei index. Methods The correlation of the intensity of W1 (the apogee of W1) and Tei index of 66 healthy adults were analyzed by Prosound a10 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.
