Hi, I am a 59yr old male, non smoker who suffers from ARVC which is controlled by drugs. Over the past few years I have been suffering from Involuntary breaths. It's as if I have to get an extra large breath which gives you a moments relief. This comes and goes, but when it is present i wish I could do it every 2 minutes and sometimes I can't and this makes me feel disstressed. What I would like to know is what is it and why does it happen? I only have to think about it for a moment and then want this breath. Sometimes I think I may be a bit potty!! but I see other people have this problem. Any help would be appreciated.
