My husband had what was diagnosed at the hospital after and ambulance drive as a panic attack. His demeanor is typically calm and has never had an attack before. He is on anti-depression medicine. They originally treated him as a heart attack victim but on the ride to hospital they said he did not and never did register. Only a CT, and x-ray of chest and monitor was done. What follow up should be done? Heart disease runs in his family, including a 65 year old brother who died of a widow maker heart attack.
