Over the last couple of years, I have been struggling occasionally with an irregular heartbeat during cardio workouts. I would consider myself very fit. I ended up at a cardiologist who did a stress test and found nothing wrong. It's been very frustrating, since, most of the time there are no problems, but occasionally, I just can't go on, even if I'm not working too hard.
I'm thinking the cause may be the NO2 Explode I've been taking. I've stopped for about a week and, so far, no problems. Has anyone else had a similar problem?
