I've got all kinds of gaps in my cardiogram which could apparently mean atrial fibrillation, but I suspect it more means that my watch is just crappy at measuring my heartbeat. Sometimes when I'm out on a walk it says 60-70 when I know I'm at 130-140. Not sure how to make my watch more accurate, it's already strapped on pretty tight.

I would also like to be able to up the number of measurements it takes. I often only use about 50% battery a day so would happily utilise the remaining charge for more regular monitoring.
- brandonb 10y agoThat's part of what we're trying to quantify with the mRhythm Study--both the accuracy of heart rate sensors on average, but more importantly, how to predict in which situations and for which people the sensor is likely to work accurately enough for clinical use. One tip I've found: if you wear the watch slightly higher up your forearm, it often gets a better reading than if you wear it directly on your wrist.
