Snapshot A 25-year-old woman with no significantly past medical history presents to the physician with concern about having recurrent panic attacks in the past 2 months. She describes that during an episode, she becomes overcome with a sense of doom within minutes and her breath becomes quick and shallow. She says she feels her heart racing, her palms getting sweaty, and feelings of lightheadedness. The attacks occur once or twice a week and have no identifiable trigger. Between episodes, she admits to a strong fear of another attack occurring, and she is considering taking time off from work because she is worried that she may have an episode during a meeting with her boss.
