Hello,
I am 16 year old male, 5' 10" and 195 pounds. I do not exercise as much as I should (mostly because it is my summer off of school) but earlier today while I was in summer school, I was sitting in the desk watching a movie in class and it felt like my heart slowed down a bit. I tried timing it and it turned out to be between 78-84 bpm. My typical pulse is 88-90 bpm so I am a little concerned. I don't get dizzy, feel faint or anything. For the past week, I haven't eaten a whole lot (definitely not 1000 calories per day) so I was wondering if that had had an affect. I just don't want to be sleeping and my heart gives out or something.
