Oh try not to think that way. I cannot speak on your breathing issues as I do not have them. As for my Exercise Induced Cardiac Arrhythmia, I was told by the cardiologist that is is extremely common and I do not worry now that I know what I have. It worried me prior to finding out and when I was sent to the Dayton heaert Hospital for testing I totally freaked out. For about 2 weeks after diagnosis I only exercised when someone else was home, you know, just in case (yes I was paranoid). Now It only bothers me when I really exerct myself, but knowing what it is, I no longer freak out.

Your doctor sounds like a great doctor, covering all basis. Once you know what you have, you can take the appropriate measures and will feel so much better.
