A similar setup which we have discussed on the previous page:

How to join sensor data from an OpenBCI board with EEG data with an OpenBCI board with ECG data?

has already been implemented by g.tec medical engineering, and was used in a PLOS One paper which validated the accuracy of the Polar OH1 sensor:

And is shown in the following picture (reprint from the above PLOS ONE paper):

• Legend reprinted from the above PLOS ONE paper:

ECG leads and Polar OH1 arm sensor placement on the participant

(b) The ECG leads connected to the g.Nautilus device. RA and LL are connected to two detachable electrodes, while LA is connected to the reference (REF) channel of the g.Nautilus.

(c) The Polar OH1 sensor on the temple is secured by a sweatband.

RA: Right arm electrode, LA: Left arm electrode, LL: Lower left chest electrode

The ECG leads are led to the g.nautilus device which is mounted at the back of the head
