i used to eat alot of junk food, but still worked out, now im eating relatively healthy, work outs havent changed much, but i will note, i dont work out daily, and sometimes its very long, other times it could be sort, and so on, anyway, today, i had fast food for the first time in months, and my heart beat started beating really fast, then when back to normal, about 4 hours later, i go to get up, and it did it again, then just stopped in about 4 seconds (when i say stopped, i mean it went back to normal), and now it seems to be beating normal, maybe alil on the fast side, but im alil scared right now, any ideas what this is?
