本文旨在确定区别孤立的第一间隔支阻塞与冠脉左前降支(LAD)阻塞的ECG特征。 自1983年10月到1992年3月经出院前冠脉造影证实共有34例患者为孤立的第一间隔支急性完全阻塞(第9组)。另有20例为LAD第一间隔支发出近端包括发出部位病变(第6组),20例为LAD第一主间隔支起始处以下病变,部分延伸至第二间隔支起始处(第7组)。多支血管病变除外。所记录ECG包括
This article aims to determine the ECG characteristics that distinguish the isolated first spacer obstruction from the occlusion of the left anterior descending coronary artery (LAD). A total of 34 patients, isolated from the first isolated acute complete occlusion (group 9), were confirmed by coronary angiography before discharge from October 1983 to March 1992. The other 20 patients with LAD first septum included proximal lesion (part 6), 20 with lesser lesion at the beginning of the first major septal branch of LAD and some with extension to the beginning of the second septum 7 groups). Except for multivessel disease. Recorded ECG included
