Went to an allergist yesterday. He told me that he could not find my pulse. He moved around on my wrist and finally found it. I used to participate in a mall walker's program that the local hospital was doing. They asked me to go walk for 15 minutes and come back, because it was so low. I get confused by it all. I was diagnosed with Atrial Flutter in 2014. I am on a beta blocker to lower the heart rate. Which is it--high or low
