Since July, I've been dealing with some heart issues. My heart rate is very inconsistent, I had a "baffling" EKG with tons of skipped beats, my heart rate spikes doing mundane tasks, and sometimes I get dizzy/start to black out during strenuous excercise. Back in December I went to my primary care doc, they listened to my heart and did an EKG and sent me to a cardiologist after hearing my symptoms. The cardiologist kind of blew me off because I'm in excellent shape, and he was comparing me to the patients he usually saw instead of comparing me to my existing baseline. He did a stress echo to rule out HCM and sent me on my way.
Some background, in a retired professional endurance athlete. I was doing 3-5 hours of high end aerobic work every day for 17 years. I know what it's like to be overtrained and I'm familiar with all side effects that come with heavy training. My current job is even more physically demanding with ~10 hours of high intensity work daily in an extremely high stress environment. When I train now, say a 6 mile run with a 50lb weight vest, sometimes I'm concerned about blacking out or failing, and these symptoms have made it difficult to perform at my best (read impossible). The symptoms went away for about 8 weeks, from mid January until about a week ago. Now they're back. My heart is simply not behaving the right way. For a while I thought I was out of shape, but then I realized something was truly off and I wasn't just being a baby. I've trained/competed through pneumonia, stress fractures, sepsis/MRSA (that one almost got me), and torn tendons. I have no problem being uncomfortable, but I do have a problem with my body not cooperating and not being at its best.
I'm not taking any prescriptions, blood work looks good, do not drink or smoke, I chew tobacco on occasion but quit for 3 months to rule it out as a possibility (this started before I ever used dip anyways). I currently take magnesium, arginine, a multi-v, beta alanine, calcium and D3 (for stress fractures), and am generally very healthy. I'm hard on my body but I take care of myself. I generally take 1600-2400 mg Advil/day (did that through my entire competitive career and I'm fine, I know it's not ideal but my stomach is bulletproof and I don't care what happens to me down the road). I hadn't taken advil in ~2 months when the symptoms started, and I started the regimen again shortly before they disappeared for a bit.
It seems really bizarre that my heart rate seems to spike bending over, jogging, or going up a flight for stairs.
I am a 28 year old male, 6'6", 250 lbs, 11% body fat. I'll try and post more if I think of any relevant information. In my experience, doctors don't know how to deal with athletes and I'm very mistrusting of them... especially the doctors I deal with, they're turds.
I'm hoping someone else here has had a similar experience and knows how to deal with it.
