The area of abnormal left ventricular(LV)wall motion on DPTI (ATL HDI 3000 with a 3.5 MHz probe) and area of LV filling defect on MCE were measured 6 hours after the coronary ligation. 测量冠脉结扎后6小时左室壁异常运动区面积和心肌灌注缺损区面积。结果：冠脉结扎后6小时，8条犬均获满意的DPTI显示，24个区域心肌活动消失，呈现紫黑色，和正常心肌间(金黄色)有明显的分界。
Left ventricular wall motion was recorded during the procedure. Positive criterion was defined as the appearance of wall motion abnormality(WMA). 左室16节段中出现室壁运动异常为阳性。
Left ventricular wall motion,BP,HR and ECG were recorded during the procedure,positive criterion was defined as the appearance and worsening of wall notion abnormality(WMA). 注射过程中观察和记录室壁运动变化、血压、心率及心电图。 左室16节段中出现新的或更严重的室壁节段运动异常 (WMA)为阳性。
Methods:The left ventricular wall motion and cardiac flow in thirty three patients with OMI were observed by two dimensional and Doppler echocardiography with Dob. 方法：在静注多巴酚丁胺的同时应用二维和多普勒超声心动图观察33例陈旧性心肌梗塞患者的心室壁运动及心内血流。
Results 6 months after the PCI left ventricular systolic function improved(P<0.05),EF value increased significantly(P<0.01)and rate of segmental left ventricular wall motion disordered decreased. 结果:患者术后6个月内心功能明显改善(P<0.
