If I measure at a truly down time (like early in the morning), it’s in the 56-58 range. During most of the day if I’ve been up and moving a little bit, I’d say about 64. I voted with the lower band.
I often check mine, because I can hear it in my ears. Often, when I wake in the morning, it is around 50, plus or minus a couple. Mid 50s later in the day. As I write, it’s 48, but that’s lower than usual.
I’ve never tested my own heart rate, but at the doctor’s office it’s typically low 60s.
I’d like it to be lower at my age (56); I am stepping up my walks to trots.
I chose 30-39 which is what it was when they installed a pacemaker. Actually 30-33. Now it is an invariant 60 (well I guess it can above with heavy exercise, which is rare).
Right now it’s 72 but sometimes it’s around 80. It’s been hard to get accurate readings when I go to the doctor because I get white coat syndrome and there it’s usually around 100 due to anxiety.
