Okay, I m overweight, have high blood pressure, smoke and drink. For the past few months I occassionally have this strange feeling in my throat. Almost like my heart is fluttering. It usually only happens for a split second and then goes away. Today was different. I have been walking around downtown Detroit all day. I drank four beers at the baseball game and smoked two joints. Back at my friend s house, I started helping clean because some girls were coming over. I got the feeling in my throat/chest again, and immediately checked my pulse. It beat hard about three times and then completely stopped for 1-2 seconds. It hiccuped a few times then started rapidly beating again. This absolutely terrified me, I KNOW that my heart stopped beating temporarily. After it started up again, I felt, and still feel, dizzy and somewhat nauseated. My Kidney/Lower back hurt for about thirty minutes and it caused me to have a moderate to severe panic attack. Unfortunately, I m out of my Xanax. I m debating on wether or not to go to the ER. My most recent EKG was a month ago and normal. What should I do? This happened about two hours ago and hasn t happened since.
