Inclusion Criteria: * All patients undergoing MIE will be evaluated for potential enrollment * Indication of cancer, esophageal dysplasia or esophageal dysmotilities * Age \> 18 years * Ability to understand and the willingness to sign a written informed consent document Exclusion Criteria: * History of chronic or paroxysmal AF, or atrial flutter * Previous severe adverse reaction or contraindication to amiodarone (e.g., pulmonary toxicity/fibrosis, hepatotoxicity, thyroid dysfunction) * Current preoperative use of amiodarone, as baseline home medication * Development of AF intraoperatively * Pregnancy * Negative pregnancy tests are required for participants of childbearing potential (PCBP) on Day of Surgery (DOS) * Breastfeeding/chest feeding * Aborted MIE operation * QTcF (Fridericia formula) \> 500 for heart rate (HR) 60-100 within 30 days * For patients with a heart rate (HR) of between 50-59 on their pre-operative screening electrocardiography (EKG), we will first review evidence of chronotropic cardiac response to exercise before inclusion in the study. If a patient's HR increases to ≥ 100 with exercise, the patient is eligible for inclusion of study. Exercise testing options may include a stair climb, a brisk walk, or supine leg-lifts prior to surgery. If exercise is not an option, we can review results of formal stress testing chronotropic response (ie. HR ≥ 100). HR monitoring can be collected by either pulse oximeter or EKG
