Fear of heart diseas: If you have been checked by a cardioloogist and told you are free of heart disease then the fear of heart disease becomes a significant problem and can cause symptoms. Talking with a psychologist or reading about getting over fears (phobia) will help you. This is a common problem--look for support groups concerning getting over fears.
