对急性心肌梗塞(AMI),迅速而准确的诊断有重要的临床意义,特别在各种再灌注过程存在时,很有可能减少梗塞面积.本研究证实,心前导联 V2—V3 出现 ST 段压低,可作为急性后侧壁 M的早期心电图(ECG)表现.方法:凡符合下列标准者,则拟诊为急性后侧壁 MI,并收入冠心病监护病房进行观察研究.(1)有典型的心绞痛,并持续超过30分钟;(2)在 V2—V3 导联 ST 段显著压低(于 J 点后80毫
Acute myocardial infarction (AMI), rapid and accurate diagnosis of important clinical significance, especially in a variety of reperfusion process, is likely to reduce the infarct size.The study confirmed that the pre-lead V2-V3 appear ST depression , Which can be used as an early electrocardiogram (ECG) manifestation of acute posterior wall M. Methods: Those who meet the following criteria were diagnosed as acute posterior wall MI and were enrolled in the coronary care unit for observational studies. (1) There are typical Angina pectoris for more than 30 minutes; (2) ST-segment depression in V2-V3 leads significantly (80 milliseconds after J point
