MSFinals-5445
A 35-year-old man who is an accountant presents with complaints of fainting spells, dizziness, palpitations and pressure in his chest. He experiences these symptoms for 5-10 minutes during which he becomes anxious about fainting and dying. He takes a longer route to work to avoid crossing busy streets as he fears getting hit by a car if he faints. He avoids public speaking and works late into the night from home, which exacerbates his symptoms. What is the probable diagnosis?
