Rapid heart rate with little or no exertion and dizziness when climbing stairs
I had three episodes of palpitations back in May and saw a cardiologist in early June who performed an EKG and stress test. He determined that I have a trace of mitral valve prolapse. I wore a halter monitor for ten days and the doctor didn't see anything concerning other than that I have occasional tachycardia for which he couldn't offer an explanation.
My resting heart rate is in the high 90's to lower 100's and it speeds up to 130 just by walking around. It will go up to at least 150 if I climb two flights of stairs, and 170 if I jog for one minute. It also increases to at least 130 if I'm walking or more if I'm walking while carrying heavy objects, such as groceries. If I'm climbing stairs while carrying heavy objects, I have severe chest pain accompanied by tachycardia. When I reach the top of a flight of stairs, Iím extremely dizzy and sometimes feel like Iím going to pass out. The same happens if I stand up after sitting for awhile. Iíve also been having intermittent low grade fever coupled with muscle pain and extreme fatigue, but I don't know if those symptoms are related.
My blood tests have come back normal except for slightly elevated CRP levels. I saw a pulmonologist, who found no problem with my lungs but after walking up two flights of stairs with me and seeing my pulse level increase and my oxygen saturation decrease on the pulse oximeter, suggested I go for a cardiopulmonary stress test.
Iím 24, female, and weigh about 128 pounds. I was going to the gym three times a week up until two months ago when I started having the palpitations. I started an aerobics regimen at home two weeks ago. I also walk as much as I can and eat healthy. I used to smoke every once in awhile but havenít in over two months. The last two times I got my blood pressure checked, it was low.
Has anyone experienced these symptoms or has a similar story to share? Thanks so much!
