Breathing Stone. Testing the ECG sheild

We needed to capture ECG using hand held electrodes.

An ECG shield for the Arduino looked perfect for prototype.  

It came with straps for your wrists and a leg (reference signal)

I wrote a program in python to monitor the ECG signal.

Here is how it is intended to be used.

But we wanted to use it on the palms of the hand so I did a few tests for the signal quality.

Could we use the hand as a reference?

Could we just hold the electrodes?

Conclusion was that it looked like it would do the job of capturing the ECG.
