I had a really really strong one doing cardio today.......as far as caffeine, like i do every time, brew about 12 cups of tea with 8 green tea bags, let that sit over night, and take 2 and a half cups pre cardio, at moderate to low intensity
I was just finishing up, i had 5 minutes left, and i felt like i got all the air sucked out of me ya know....pretty big skipped heart beat.....than right afterwards, i had some irregular hear beats....ya know, where you feel your heart beat and it kind of feels abnormal, and like its not pumping blood at all, maybe like a flutter, not sure if thats what its called.....had maybe 2 or 3 of those.....I immediately stopped cardio, took some deep breaths, told myself the heart muscle is not at all perfect, and palpatations are very normal and happen from time to time...and can also be stimulent and exercsise induced, and in no way is an indication of a problem...
I can honestly say, i havent had one like this in 2 years, same thing happened, but just alot less intense, once during cardio a couple years ago...
walked it off, felt fine, but damn, it shook me up a little...
well, just needed to vent, and wonder if anyone else has had these
