Long Q Interval Any swimmer's out there who have this?

I was recently diagnosed with a Long Q Rhythm. I'm wondering if there is anyone else out there with this problem. My Dr. recommends Beta Blocker and no more racing. He also commented that I've had this condition all my life so I'll probably be ok. I would like to PM with anyone out there who is swimming with a similar situation. I am feeling very conflicted and would like to talk to someone in the same boat. I read the paragraph about the sisters who swam in Nationals with a Long Q diagnosis, in fact that article motivated me to go to the electrophysicist (sp) and get this checked out by a specialist.
