My heart rate is always low - whenever I’ve been in hospital for anything I always set the monitor alarms off as they’re usually calibrated to go off with heart rates of less than 50bpm. My resting heart rate is usually mid 40s but often drops down into the high 30s. I’m pretty active but definitely not elite athlete levels of fitness. I’m early 60s, normal blood pressure, not overweight. I’m torn between thinking that someone’s got to be an outlier and that this is normal for me and wondering if I should get it checked out properly?
