Good day everyone! I am a new member of the forum. I was looking for advice if anyone else has had feinting or near-feinting spells during running, even though you feel amazing.
I am a man of 57, I usually run 3-4 times a week on a treadmill when the weather is not nice. Occasionally and semi-frequently, I am running along, and feeling fantastic, when all of a sudden a tsunami sized wave of dizziness that makes me want to feint immediately. Most of the time I collapse, or sometimes I can just place my feet off the treadmill and hold on until the discombobulation goes away. Usually about 30 seconds. I don’t understand it because I feel so great before it comes on. I went to a cardiac specialist doctor, angiogram came out great, they strapped me with sensors to monitor my heart activity during a normal day and he saw no problems. I’m 6 foot and 165 pounds and in good shape, otherwise.
Has anyone had similar experiences?
