title: Unusual U wave induced by reconstructed retrosternal esophagus.
abstract: The present case shows that a broad compression of the right ventricle by the reconstructed stomach tube after esophagus cancer surgery induced an abnormal U wave. When facing an abnormal ECG, we should keep in mind of the mechanical compression to the heart as a differential diagnosis.
