Methods:Mitral annular velocity in early diastole(Ea)and late diastole(Aa)in normal and hypertensive patients by Dopper tissue imaging(DTI)were studied, also mitral inflow velocity E,A in hypertensive patients by Doppler flow imaging were detected.

• 方法 :以多普勒组织成像技术分析正常人和高血压病患者二尖瓣环的舒张早期运动速度 ( Ea)、舒张晚期运动速度 ( Aa) ,比较两者的不同。 并用血流多普勒法检测二尖瓣口舒张期流速 E,A,分析高血压病患者血流参数的异常。
