That looks like a very interesting write-up about ECG, and I'll read it properly tonight when out of the office - thanks for writing!

I'm a Garmin Edge user of many years, always interested in HRM during activities. But that's not something I wear all the time. Hopefully when my Pebble Time 2 arrives something similar can be done on that platform.

I'm intrigued to see what sort of details may be captured from such a seemingly simple device.
