that happens to me though not when i'm standing, i can be sitting down or even lying down w/ 50-60bpm and get the chest pain or standing (with sig. higher numbers ) and have chest pain... so sorta? yea. i have had that if you allow for lying down. but with the irregular beats i have that quite often, sometimes several times a week (my bp cuff tells me if it measures irregular beats...how awesome is that lol) with either low or high bpm. wonder why? hmm... well i'm glad you're feeling better now at least!!!
