This is a preprint and has not been peer-reviewed. Data may be preliminary.As it can clearly be seen, they described the terminally inverted T wave (exactly the same description by Wellen et al.) as inverted U wave syndrome. This fact that unfortunately the same syndrome is described as two separate conditions is extensively discussed by Movahed (5,6) but the authors failed to reference these papers. Another EKG published as an inverted U wave by Savori et al. et al (7) describing inverted U wave syndrome is exactly the same as Wellen's EKG: Dr. Gerson's group should get the initial credit for describing and publishing this phenomenon before Dr. Wellen. However, not mentioning Dr. Gerson in their publications, it created confusion in describing this EKG pattern in the medical community. Since original descriptions of this EKG abnormality by Dr. Gerson and Wellen, this pattern has been confirmed and recognized numerous times by many clinicians but only described by some authors as Wellens' syndrome (8-11) while others only mentioned it as inverted U waves (12-14) but never both until we published about this fact and this confusion (5,6).
