平均年龄61(38～77)岁的连续50(男35、女15)例急性下壁心肌梗塞患者,于胸痛开始后34.2±8.9小时内接受两维超声心电图(2-DE)检查,随后8小时内进行平衡法门电路血池成象(GBPS).GBPS和2-DE分别检出右室壁活动异常22例和20例.其中18例GBPS和2-DE均阳性,4例GBPS阳性而2-DE阴性,2例GBPS阴性而2-DE阳性,另26例GBPS和2-DE均阳性.以GBPS结果为基础,检出右室心肌梗塞的敏感性和特异性:2-DE为82%和93%,(入院当时心电图)V_4R导联ST段抬高(≥0.05mV)为50%和
A mean of 61 (38-77) years of consecutive patients with acute inferior myocardial infarction of 50 (35 males and 15 females) underwent two-dimensional echocardiography (2-DE) within 34.2 ± 8.9 hours after onset of chest pain followed by 8 (GBPS) .GBPS and 2-DE were detected in 22 cases of abnormal right ventricular wall activity and 20 cases of which 18 cases of GBPS and 2-DE were positive, 4 cases of GBPS positive 2 -DE negative, 2 GBPS negative and 2-DE positive, and the other 26 cases GBPS and 2-DE were positive.Based on GBPS results, the sensitivity and specificity of right ventricular myocardial infarction were detected: 2-DE was 82% And 93%, (ECG was admission) ST segment elevation V_4R (≥ 0.05mV) was 50% and
