Hello all, today I had a stress echo and experienced several pvcs at heart rate of 165-170 bmp. After I laid down for the echo they disappeared. I never ever get my heart rate that high, and the doc said my echo looked good. I'm confused, he said he would take a better look and call. Everything was fine until I reached 94% of my max rate which is 181 and I'm 39. Could this be do to being out of shape and never getting to that heart rate or maybe there is a blockage the echo isn't detecting.
