As most of you know already, I struggled with an ED for a number of years. One of the problems that plagued me during that time was heart palpitations. I still get them from time but I don't fret much about it, they're pretty far and few between at this point. But lately I've been noticing during my runs that I've been getting a bit of arrhythmia. My heart rate kind of bottoms out for a few seconds then bounces back up. Is this something that may be related to that? I used to workout like crazy during my ED years, so I've dealt with palpitations during a workouts before, but I don't much like it. I don't really want to have a bad instance one day and pass out mid run or anything. I workout at 6am and I know it's bad bad bad but I don't eat before I go. I have a bad stomach and eating first thing after getting up makes me sick. I've always worked out on a empty stomach, so my body is used to compensating. Is there a reason for this quick fluctuation of my heart rate mid workout? It's usually during the more intense parts of my runs or workouts and it makes me a bit light headed for a second or two. How do make this not happen anymore without compromising the intensity and duration of my workouts?
