Some time ago I was sent to A&E with suspected pancreatitis (diagnosis was a prolonged (several weeks) period of indigestion). Whilst being observed, the nursing staff noted that my heart rate was low, especially concerning the stressful situation which I was in. I was plugged in to an ECG for further obs, but as there was no irregularity in my heart rate, I was discharged.
I wear an Apple Watch, which measures my heart rate. My pulse seems to vary wildly throughout the day, often for no discernible reason. The attached image shows my heart rate whilst sitting on a train (17:21-18:21), immediately on completion of a one-mile walk home 18:35, and whilst sitting on the sofa 18:36.
I'm 40, white British (with the obligatory smattering of Irish), 5'10" and c.17st. My fitness isn't great, as I'm recovering from a kayaking injury, but I've previously been in better shape. I don't drink and haven't smoked since February 2014 (although I do vape).
Should I be concerned by these irregular results?
Thanks for reading the ramblings of a concerned chap,
