为探讨高血压病患者运动负荷心电图出现的ST下移(ST-dep)与倒置U波(NU)的临床意义,作者以高血压病患者30例为对象,行仰卧位踏车运动负荷试验。从负荷前至负荷后连续记录心电图,检测缺血性ST-dep、有无NU及V_5R波高度。从负荷前至负荷后每3分钟记录心超声图,计算左室射血分数(LVEF)。结果:负荷中ST-dep14例(47%),NU18例(60%)。ST-dep(+)组比(—)组高血压病病史长、最大负
To investigate the clinical significance of ST-dep and U-wave inversion in patients with hypertensive patients undergoing exercise-load electrocardiography. Thirty patients with essential hypertension were enrolled in this study. The electrocardiogram was recorded continuously from the pre-load to the post-load, and the ischemic ST-dep was examined with and without NU and V_5R wave heights. Cardiac echocardiography was recorded every 3 minutes from pre-load to post-load, and left ventricular ejection fraction (LVEF) was calculated. Results: ST-dep14 patients (47%) and NU18 patients (60%) were under load. ST-dep (+) group than (-) group had a long history of hypertension, the largest negative
