The last time I was at the ER I asked the doctor what causes afib, and she said the #1 cause is alcohol abuse. She said that's why it's called the Holiday Heart. Has anyone else been told that? I did not consider myself an alcoholic. I had usually 1.5 glasses of wine after dinner about four nights a week, then I would not have any alcohol for a day or two. I did drink more when I was younger, but found as I got older if I drank more than 1.5 glasses in an evening, I didn't feel good, so I cut back. I used to drink two glasses a night, and occasionally, maybe once a month, would get carried away, usually when I was with family or friends. Now I'm wondering how much harm I did to my heart without knowing it.
