What is it when you just are sitting watching a movie, inside your head, anxious and your heart starts to race, then cold water helps

[braziljjay]

I remember this happening to me years ago. I was just sitting watching a movie with my GF at the time and her brother. I think I took a hit of some weed but not a strong puff. Everything was going okay and then out of no where my heart starting to race/pound. I thought I was dying. It slowly came down back to normal. could it be that an anxiety/stress related hormone or chemical was released and caused this sudden shift in my heart rhythm or what?

I had this happen to my yesterday. I was watching Apocalypto and was so into it, like intensely, got real inside my head, was starting to feel real anxious.(A side note ordered KFC) I say that as I know fatty fuids, salt is a trigger especially from junk food like KFC. I have ordered stuff before but nothing happened. Anyways

all of a sudden I noticed a pattern shift in my heart like a micro second of irregularity and then it went full on fast, pounding for 2-3 minutes. I breathed and splashed cold water on my face and it went down gradually to normal. No other symptoms like dizziness or chest pain or anything.

I was like really feeling anxious. I have stress/anxiety problem and am doing things to mitigate it like workout everyday, eat right(Just had a cheat meal yesterday) meditate . I haven't been hydrated as well as I should have been. Drinking a lot of coffee/tea but they are decaf

I did some research and a doctor said Afib is a sudden onset of a fast heartbeat or irregularly heart beat followed by a sudden return to normal.

A panic attack he said, the heartbeat comes down slowly. That was my case.

Wondering if anyone experienced this and what can I do to prevent this from happending again. what do you think, was it the anxiety or was it the KFC ?

I have no other symptoms, workout like a savage and don't even get flustered or out of breath, I don't drink, I don['t smoke, etc I'm just have a lot of stuff on the go in my life but not too much but I noticed that when I get inside of my head as I did yesterday I feel like impending doom. Maybe I should just chill more and relax ..

Thanks
