Various U-wave and TU-segment abnormalities have been described and ascribed to certain cardiac pathological conditions. In this case report it is hypothesised that prominent U waves in the inferior leads are caused by an accessory papillary muscle. Any possible long-term consequences are not known.enClinics CardivU wavePapillary muscleElectrocardiographyHeart -- Diseases -- DiagnosisArticle
