When had covid got off most blood pressure meds, cause bp was low and made me real tired. Then just walking to bathroom, heart rate went up to 100, so Heart doc put me on 5mg bisoprolol, a beta blocker. It has dropped my heart rate. Now I'm averaging about 60 all the time. His NP says that's fine, I asked her if a low pulse was hindering me getting oxygen to my lungs, (and to the rest of my body) but she said no. She said 60 - 80 is good.
