Hi,
That did't sound like a nice event. Hope your ok.
my first thought is that may have been a vasovagale syncope
a link to explain:

I have this a lot... its not fun, especially when it takes hours to feel good again.
I also turning grey, unconscious, and nausea/vomitting and sweat...
but I don't know how it feels if its during a fast arrhythmia.
I agree with cindy707, get all the relevant test's you can get.
Good luck! hope this is the first and the last pass out.
Wow i am so sorry that this happened to you and thank goodness that you had your husband with you when this occured. The outcome could have been very different. When you say that the docs couldn't come up with anything....are you talking about a heart doc? My suggestion would be to contact your heart doctor and ask them because of what happened if you are a candidate for a holter monitor for a week or so to try to catch what ever it is that they suspected has happened to see if it was heart related. The holter is a wonderful tool in catching any type of episodes that may occur during your daily activities. One thing i certaining would not do is to give up looking for the answers from a physician until you got those answers. You don't want to be alone if this occurs again. Good luck to you on this.................
