Interesting, Jurdoc! I just read about arrhythmogenic right ventricular dysplasia.

You have that in your genetic heritage that you know of? Are you of Italian or Greek heritage? Did you have a v-tach event or was someone smart enough, after you fainted, to do an EKG and an echo and diagnose the problem before you did?

I suspect that, for you, even holding in a breath of air is enough interruption--or was before your debrbillator, at least--to give you some syncope, right? If I can ever get him away from the football game long enough, I want my husband to come read this.
