title: U wave inversion in unstable angina due to left main coronary artery stenosis.
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.
