Went out last weekend doing some exploring with friends and on last pitch starting feeling quite out of breath, but the snow was deep. On the slog through the woods to intersect hiking trail I was so out of breath and my heart is not behaving itself, quite irregular. I have afib but this is controlled with meds , but this was different. I almost passed out a number of times heading down the packed trail, at one point having to go down to a knee. Rick Peverly,formally of the Bruins had a very similar incident happen to him the next day after mine, but he almost died!
I've seen my Cardiologist since and we've started tests but I don't see anymore climbing in my near future. I am normally a mountain goat, this has made me an old man quickly, but will be back to goating as soon as we figure this out.
