Don't take this lightly...
On the extream end I have seen a few outwardly appearing competative athlets succum (die) of this condition...
If its real its going to take allot of training and control to stay fit...
I have seen this conditon worse in competitive weight lifters using "The Juice" or similar agents...
Look for a cardiologet who rides and listen to what he says...
You can change your life to accommodate this condition and still have a fun life...
