I am a healthy 30 yr old athlete. I've trained 5-6 days per week for the past 5 years. I have recently increased my intensity and started a very demanding cardio and circuit training routine on top of my weight training routine. I have always been very careful not to over stress my body. I have gradually approached this new training regimen. I am in the gym no more than 1 hour to an 1.15 per day. I eat healthy/clean, sleep well, do not drink or smoke. I do include some supplements in my diet, but nothing in excess. These include fish oil, multivitamin, whey and caesin proteins and glutamine. For the past two weeks I have started to notice palpitations. They feel like skipped beats, pauses. extra hard beats--similar to those described by people experiencing PVCs and PACs. The only change I can pinpoint that I have made since they have started has been the increased intensity in the gym and added cardio. I do not have any other symptoms other than feeling these palpitations--no dizziness, chest pain, or tiredness. The palpitations usually occur at night when I am at rest, after meals, and when I'm lying down on my side. They do not seem to occur during exercise. I have gone to my gcp and was given an ekg (normal). He explained that in most cases these palpitations are benign, but put me on the 24-hr holter monitor (still awaiting results) and took blood (still awaiting results). He said I can continue to exercise as usual for the time-being. But wants to look over the holter results and if the palpitations aggravate me, he suggested possibly taking a beta blocker for a few weeks to clear them up. The fact is though, I'm worried about my heart and can't believe it's anything less than serious. This feeling is very frightening to me. I'm reluctant to push myself now in the gym and it has quite dramatically impacted my daily routine--and its only been a few weeks. Yesterday, the whole day I was fine than whamo, they hit from 7pm to 11pm. Every few minutes I'd feel one and sometimes I'd experience a few every minute. I try to do everything to stay healthy yet I have these new symptoms. It's very frustrating. Maybe its tension and anxiety they is just building up or something. I can't really say. Sorry I just needed to vent how I feel because nobody around me thinks its a big deal. Thanks for reading!
