I work out 5x per week, also play a lot of singles tennis so sweat a lot, use Surge Workout Fuel and Surge Recovery, Creatine, Spike, etc.--but they are not the issue, I don't think, except maybe Creatine. Five weeks ago developed an irregular heartbeat. Cardiologist tells me I have very healthy heart but a benign, maybe reversible irregularity, a magnesium deficit and probably dehydration, which may be causing the irregularity. But my cardiologist is not a sports doctor or nutritionist.
I thus desparately need advice from a sports nutritionist who is familiar with guys who work out vigorously and often, use but don't abuse pre and post-workout supplements (I do stack them sometimes), and have experienced benign heart palpitations. I stopped the supplements four weeks ago, but the irregularities have not gone away. Magnesium oxide helps.
Any advice would be really welcome, since many excellent doctors know very little about the effects of serious weight training, coupled with other exercise and what can cause those imbalances. The good news is the cardiologist thinks I'm in great shape--except for what is called PAC, which he's not worrying about, but I sure am.
