WebECG Results The ECG showed less than 1 mm of ST elevation in V2-V3 associated with mild T-inversion/biphasic T-waves. T-wave inversion was also seen in lead III, where it is often normal when the QRS is primarily negative, but here the QRS was mostly positive, making it more likely abnormal. U-waves were also seen in leads V2-V5. The 'U' wave is a wave on an electrocardiogram (ECG). It comes after the T wave of ventricular repolarization and may not always be observed as a result of its small size. 'U' waves are thought to represent repolarization of the Purkinje fibers. However, the exact source of the U wave remains unclear. The most common theories for the origin are:
