在1987年7月至1989年12月30个月内收入冠心病监护病室的所有病人的心电图中(ECG),发现26例陈旧性心肌梗塞病人有一种与右束支传导阻滞(RBBB)或左束支传导阻滞(LBBB)无关的异常ECG图象-RSR’复合波,伴以宽大的QRS(≥110ms)。病人分为三组:组Ⅰ(n=13)RSR’复合波位V3至V6的一个或多个胸导联上;组Ⅱ(n=9)RSR,复合波位Ⅰ、Ⅱ、aVF的一个或多个下肢导联上;组Ⅲ(n=4)RSR’复合波位上述胸导联和下肢导联的一个或多个导联上。组Ⅰ8例ECG出现异常Q波;组Ⅱ有4例;组Ⅱ未见异常Q波。 26例中24例经平衡法放射性核素心血管造影术(ERNA)和另2例用二维超声描记术(2-DE)发现室壁节段运动异常(包括运动不能和运动障碍).
The electrocardiogram (ECG) of all patients admitted to the coronary care unit from July 1987 to December 1989 found that there were 26 patients with old myocardial infarction who had either a right bundle branch block (RBBB) or Abnormal ECG images unrelated to LBBB-RSR complex with broad QRS (≥110 ms). The patients were divided into three groups: one or more of the chest leads from group V3 (n = 13) RSR ’complex with V3 to V6; a group II (n = 9) RSR, Or multiple lower extremity leads; Group III (n = 4) RSR ’complex loci on one or more of the leads of the chest and lower extremities described above. Group Ⅰ Ⅰ ECG abnormalities in 8 cases of Q wave; group Ⅱ in 4 cases; group Ⅱ no abnormal Q waves. Twenty-six of the 26 patients had abnormal wall motion (including motor failure and dyskinesia) with balanced radionuclide cardiovascular angiography (ERNA) and the other 2 patients with two-dimensional ultrasonography (2-DE).
