Hello All,
I'm a 28 year old male in good physical condition. I workout 3-5 times a week and have a pretty healthy diet.
Last week I suffered from a quick onset of horrible dizziness. I could barely move my head or even open my eyes without getting dizzy and nauseous. The next morning, I woke up feeling pretty good and just had a slight bit of dizziness. I thought I was quickly recovering from whatever element I had. That night, I was struck again with extreme dizziness and nauseousness.
The next morning I went to the Dr. I was feeling a bit better. The nauseousness was gone, but he dizziness was very apparent. He checked for an ear infection, but none was evident. My blood work was also good. When he took my pulse, my resting heart rate was 46 (about 10-15 beats lower than it had been in my last two visits to see him). An ECG showed some irregularities and a pulse of 43. For the next few days I monitored my pulse and it was between 48-52 with a pretty good deal of dizziness. For the last 3 or so days, my pulse has been normal all day. I have had no nauseousness and my dizziness has become ALMOST eradicated.
Currently, I am waiting on my cardiologist appointment to occur. In the meantime, both a nurse and a surgeon I am friends with have told me (independent of one another) that the problem maybe with my Vagus Nerve being overstimulated. According to most things I have read, this seems like a reasonable explanation for the first couple of days of my experience. However, if the Vagus Nerve is overstimulated and causing bradycardia, which is causing dizziness, what explains my slight dizziness the last few days even though the bradycardia has disappeared?
Thanks in advance.
