I get an arrhythmia. I don't get it a lot right now. In fact, I haven't had it for a while. BUT, I watch my heart rate and don't get it up to high for too long. So, I live a relatively low key lifestyle to deal with it. I'm hoping that can change someday.
I have had it for quite a while now and I have come to the conclusion that foods definitely can be a trigger. Onions for me.
Also, I think metal toxicity can cause them. If you're a nonnie, this could be a real possibility for you. There are many causes and that is the big challenge with regular M.D.'s. They're pretty much reserved to not figuring out why, but treating the symptoms. In their defense, there can be so many causes, it's hard to peg. Yet, they don't even seem to even care to try. Except the fact that they may tell you to watch your caffeine intake. That actually seemed to help me, as I don't drink anything with caffeine in it. I will eat a little bit of chocolate here and there. But I used to drink lattes every day. And I used to get them regularly. Although I was a lot more active back then also.
I hope you find out what triggers it for you and how you can deal with it. I have a friend that has A fib. And he had another type of arrhythmia also. One he got the zap treatment for and that seemed to work, after the 2nd time. But they told him there wasn't any procedure to deal with the second arrhythmia. The drugs made him feel so horrible, he just deals with it, as it is intermittent and many times it pops up when sleeping.
