ECG Badge

I would like to create a wearable ECG. This would monitor your heart rate and display it on a small badge. Like this (you will need to click to see my dodgy gif animation)

I don’t know if this is possible, but my research thus far hasn’t rule it impossible yet.

Update: I found this tutorial using a Xprotolab oscilloscope to display heart rate. Once I locate the very tiny oscilloscope, I will give it a try!
