[expunged]

I wish I had more to offer, here.

I don't think there are, but I'm not a doctor.

It's usually tested for genetically or with an ekg. It doesn't have any outward physical signs or traits that I'm aware of. There are several different subtypes and each has different triggers; so diagnosis usually happens in response to an event. For example, passing out when the phone rings because you're surprised. I don't think a lot of doctors know much about it. In my case, I didn't find out I had it until I was in my 40s and that was because I made contact with my biological family (I'm adopted) and they told me I needed to get checked for it.
