A patient in their late 40s was admitted to the hospital to receive a uterine myomectomy procedure. The patient had no history of structural heart disease, hypertension, myocarditis, or sleep apnea syndrome, and denied a family history of cardiovascular disease and sudden death. The patient had not received any pharmacologic agents that would affect cardiac rhythm. Biochemical evaluation showed normal levels of whole blood cells count, electrolytes, myocardial enzymes, and brain natriuretic peptide. A 12‐lead electrocardiogram (ECG), chest radiographic imaging, and echocardiographic findings showed no abnormalities. To assess the risk of general anesthesia, the patient underwent evaluation with a Holter monitor, which recorded the patient’s cardiac activity during the syncope (Figure, A).
