Three patients are presented in whom an isolated inversion of the U wave preceded by several hours typical electrocardiographic changes of an acute myocardial infarction. The association of transient hypertension and an acute U-wave inversion during this period of myocardial ischemia is discussed. It is suggested that within the appropriate clinical context an isolated U-wave inversion may portend an acute myocardial infarction.
