Is 12 Lead ECG possible with Cyton?

I have previously used Cyton for single lead ECG measurement.
I have observed that in Open BCI GUI only 8 channel data is shown. I want to know is it possible for me to record 12 lead ECG (10 electrode - standard placement) in cyton.

    Hi Veda,

    There is a FIVE lead tutorial. But how could a 10 electrode requirement work, with only 8 channels? If you had the Daisy (16 channels) that can work.


  • Thank you wjcroft.
    I do have Daisy board. Is there any 12 lead tutorial with Cyton+Daisy board available? It would be much helpful for me.

    Thank you wjcroft for the reference.
    I have sorted the connections as below. Please check whether I can proceed .

    All electrodes are placed as per standard 12 lead ecg placement.
    Since V1-V6 electrodes are single ended which are used with WCT (Wilson central terminal) in ADS1298R, how do I incorporate the same in ADS1299?
    Is connecting to SRB sufficient as shown in above image?

    Sorry, I did not study the link I gave in detail. You're going to have to figure this out yourself. Obviously for single ended chest leads (V1 through 6) you are going to need some type of electrical reference. SRBx can work, but note the default ADS1299 configuration is bussing all the INxP pins as SRB2; and then using the INxN pins as channel inputs. You will need to adjust your 'hardware settings' and pick an appropriate reference point and appropriate SRBx.

    Since the link I gave is an actual hardware implementation of 12 lead, I assumed they had to figure out the same issues. Re-read their documents carefully.
