近些年来,学者们发现急性下壁心肌梗塞早期心电图胸前导联伴ST段下降者,其心功能明显减退、并发症增多,如心源性休克、心律失常,死亡率亦高。有作者在研究了此类患者的预后时指出:急性下壁心肌梗塞伴ST段下降是临床筛选高危患者的指征之一。基于对此种心电图变化的临床意义探讨,笔者回顾性地总结分析了如下资料。病例系1983年1月～1988年9月按WHO标准确诊的34例急性下壁心肌梗塞患者。不包括合并前间壁、前壁、侧壁心肌梗塞和陈旧性心肌梗塞、右室梗塞及束支传导阻滞或发病时间不清楚者。ST段下降以入院时心电图记录为准。根据胸前导联ST段下降将34例患者分为两组,I组18例,男性14例,女性4例,平均年龄63(43～83)岁,V_1～V_5至少有两个导
In recent years, scholars found that acute inferior myocardial infarction in patients with early chest ECG leads with ST-segment decline, its cardiac function decreased significantly, complications increased, such as cardiogenic shock, arrhythmia, mortality is also high. Some authors in the study of the prognosis of such patients pointed out: acute inferior myocardial infarction with ST segment decline is one of the indications for clinical screening of high-risk patients. Based on the clinical significance of such ECG changes, the author retrospectively analyzed the following information. Cases from January 1983 to September 1988 according to WHO standards confirmed 34 cases of patients with acute inferior myocardial infarction. Does not include the merger of the anterior wall, anterior wall, lateral myocardial infarction and old myocardial infarction, right ventricular infarction and bundle branch block or the time of onset is not clear. ST segment decline to admission ECG records shall prevail. Thirty patients were divided into two groups according to the ST-segment descending of the thoracic aorta. There were 18 patients in group I, 14 males and 4 females, with a mean age of 63 (43-83) years. V_1-V_5 had at least two
