I will start with saying that I am 26 and a male. I had an ablation for WPW in 2004, and haven't had an episode of that since. In the fall (September and October) I had a complete cardio workup. I had a holter, many EKGs, a stress test, an echo, and an event monitor. All of this stuff turned out normal. They told me most of my symptoms were caused by anxiety. I went to a counselor, and was taking ativan as needed. I was doing really well for most of the winter. Then all of a sudden about a month ago I have what I thought was just anxiety rearing its ugly head again. My hear rate has been higher than usual with normal tasks. I have also had shortness of breath with normal tasks and feel like some days I cannot exert myself at all. Last week I ended up going to the emergency room because my heart rate was at 170, and I had just been sitting around. They hooked me up to the heart monitor, and did an EKG. They basically said everything looked normal, and it was just sinus tachycardia. So this was probably just due to anxiety.
Fast forward to today. I was walking to class today (normal speed, not hilly or steps at all). I started to get dizzy, and my heart was up to 150 bpm. I took an ativan thinking this was just anxiety as I had felt my heart and it seem to be beating regular. Later in the day, however, I was working. I was doing some lifting of boxes from probably 5-40 pounds. I started to get kind of the same dizziness and leg weakness as before, but this time my heart rate was only in the 130s. I was wearing a polar heart rate monitor at the time. The thing I found weird though was it would fluctuate. The watch would tell me 130 and then like 5 seconds later it would go down to 100, but then it would get right back up to the 130s and 140s. It would just fluctuate like that for a while. I sat down at relaxed for a while, and things seem to normalize. Then I get home and was feeling pretty good, but walked up the stairs sort of briskly and now my heart has seemed to be fluctuating again. Like just a few minutes ago I was laying down at it was at 90, but suddenly dropped to 64, and worked it's way back up.
I am not sure if this is enough to determine it was really a fib or not. It all could just be anxiety again, but it certainly doesn't feel like it. Any input you guys could give would be great. I want to get another appointment with my doctor to see if I can get a holter monitor, but he is determined to tell me all of this is just anxiety (which I guess it could be, but to me it seems like my heart is not beating "normally").
Thanks in advance for any input! :)
