In 30 patients with old anterior myocardial infarction, body surface isopotential maps were correlatively studied with left ventriculographic findings. In 25 patients with ventricular asynergy restricted to the anterior segments, surface potential abnormalities due to infarction were observed during specific phases of QRS and in specific portions of the chest surface depending on the location and extent of severe ventricular asynergy (akinesis and dyskinesis). However, the remaining 5 patients with co-existing severe asynergy in the inferoposterior segment, showed body surface potential maps quite different from those of the above 25 patients. It was suggested that body surface isopotential maps were useful in detecting the location and extent of ventricular severe asynergy in patients with old anterior myocardial infarction.
对30例陈旧性前壁心肌梗死患者的体表等电位图与左心室造影结果进行了相关性研究。在25例室壁运动不协调仅限于前壁节段的患者中，根据严重室壁运动不协调（运动不能和运动障碍）的部位和范围，在QRS波的特定时相以及胸壁表面的特定部位观察到了梗死所致的体表电位异常。然而，其余5例下后壁节段同时存在严重室壁运动不协调的患者，其体表电位图与上述25例患者的体表电位图有很大不同。提示体表等电位图有助于检测陈旧性前壁心肌梗死患者室壁严重运动不协调的部位和范围。
