driven right leg ecg

[fredjmartins]

Greetings,

I'm looking for information about how to create a Labview program for ecg acquisition with the driven right leg.

I'm using the DAQ 6212. I've been able to do the diferential between the two input electrodes, but I'm having some trouble with the feedback.

Any help would be useful. Thank you!

A full Bio-Medical Toolkit is available ($1000):  http://sine.ni.com/nips/cds/view/p/lang/en/nid/211023   

More info on Bio-Med resources in LabVIEW here:  http://www.ni.com/white-paper/5593/en/

Isn't there any other option?

I have no budget to buy the biomedical toolkit.

Check the second link for a page of other links that will give you info on various bio-med applications.  The toolkit is nice but you don't really need it.  Unfortunately though, it means you will probably have to program a lot of the functionality yourself.  Do a search on this forum for "biomedical", ECG, EEG and other relevant phrases and you will find that lots of other people are doing similar work and may be able to help you along.  Also study the LabIEW tutorials of course.

Thank you very much.

I've already looked at the links and found some useful information and gave me some new aproaches. Unfortunately none of them were very effective.

The feedback circuit seems to be a very big puzzle to me to unravel since I have to do all the signal processing digitally and not with analog circuits.
