Tissue Doppler imaging to assess right ventricular function in hypertensive heart disease with normal pulmonary pressure / 中华超声影像学杂志

ABSTRACT

Objective To evaluate right ventricular(RV) myocardial profile changes in hypertensive heart disease (HHD) with normal pulmonary pressure by pulsed wave tissue Doppler imaging(PW-TDI) technique,and to assess right ventricular function.Methods Group Ⅰ was normal control,20 cases,average age (54?7) years old,while group Ⅱ was primary hypertensive heart disease,20 cases,average age (58?8) years old.PW-TDI technique was used to measure the peak systolic,early diastolic,late diastolic velocities(Sm,Em,Am) of right atrio-ventricular ring,the ratio of Em/Am,right ventricular isovolume contracting time(RIVCT) and isovolume relaxation time(RIVRT).The systolic and early and late diastolic motorial amplitude(SD,DED,DAD) were measured by M-mode echocardiography.Results In groupⅡ Em decreased [( 16.0? 2.7)cm/s vs ( 19.5? 3.4)cm/s,P
