I wonder if you are concerned about your HR because so many joggers and distance
runners brag about their unusually low
heart rates. When the people who talk about it are talking 50, 60, even lower, it's easy to fall into thinking yours is too high. Since surgery, I have been watching my vital signs gradually stabilize, and thinking HR wasn't keeping up, until I finally looked into norm data and figured out that my expectations were unrealistic for that reason.
