左主干闭塞(LMCA)心电图有多种表现,该文研究入院时心电图QRS宽度与急性LMCA元再流现象的相关性。 方法 1999年1月～2002年1月538例接受血管成形术的急性心肌梗死具有左主干病变患者16例,男性13例,女性3例,均成功置入支架,解除狭窄后3例患者有前降支狭窄,1例具有回旋支狭窄,对狭窄处采取了血管成形术治疗。16例患者中仅有1例接受静脉溶栓,14例采取了主动脉内
Left Main Lobe (LMCA) Electrocardiogram has several manifestations. This article investigates the association of ECG QRS width with acute LMCA regurgitation on admission. METHODS: From January 1999 to January 2002, 538 patients with acute myocardial infarction who underwent angioplasty had 16 patients with left main disease, 13 males and 3 females, all of whom were successfully placed in the stent. Three patients had stenosis The descending branch was narrowed, with a narrowing of the circumflex artery and angioplasty in the stenosis. Only one of 16 patients received intravenous thrombolysis and 14 received intra-aortic
