i have had these attacks all my life and i am now 55 years old. i havent known that these are "attacks" that have plagued me. my breathing will get rapid, heart rate increases, chest pain and all the other signs/symptoms of a heart attack. since my diagnosis i have tried yoga deep breathing exercises to keep these "attacks" from accelerating to full blown. this method has helped somewhat. i seek input from you all on methods you have used and hopefully can apply what you have learned to my own personal situation. thanks for all the help
