A previously healthy 24-year-old woman comes to the physician because of recurrent episodes of a choking sensation, palpitations, diffuse sweating, and shortness of breath over the past 3 months. These episodes occur without warning and last for about 10 minutes before gradually resolving. One episode occurred while at a shopping center, and she now avoids busy areas for fear of triggering another. She has been evaluated in the emergency department twice during these episodes; both times her ECG showed normal sinus rhythm and serum cardiac enzymes and thyroid hormone levels were normal. She does not currently have symptoms but is concerned that the episodes could occur again at any time and that there may be something wrong with her heart. She does not smoke or drink alcohol. Her only medication is an oral contraceptive. Vital signs are within normal limits. Physical examination shows no abnormalities. Urine toxicology screening is negative. Which of the following is the most appropriate next step in management?
