We herein report a 34-year-old man who presented with recurrent palpitations that occurred while swallowing solid food. Holter monitoring revealed atrial tachycardia (AT) while eating. In addition, chest computed tomography (CT) showed a small nodule in the front of the ascending aorta. Thoracoscopic surgery was performed to remove the nodule; a pathological examination revealed that the nodule was a thymic cyst. The AT disappeared postoperatively. This case demonstrates that a mediastinal nodule can cause swallowing-induced AT.
