Abstract
A 50-year-old male was admitted to hospital for repeated episodes of chest pain due to unstable angina. Serial electrocardiograms were all normal except for one electrocardiogram, recorded during chest pain, which showed isolated U wave inversion in leads I, V4 and V5. Subsequently, selective coronary arteriography showed isolated 99% stenosis of his left main coronary artery.
摘要
一名50岁男性因不稳定型心绞痛反复胸痛入院。除了在胸痛发作时记录的一份心电图显示I导联、V4导联和V5导联出现孤立性U波倒置外，系列心电图均正常。随后，选择性冠状动脉造影显示其左主干冠状动脉孤立性狭窄99%。
