Dear Aspired


SCXI is great for this sort of biomedical application as there are
isolated amplifiers available. We've used the SCXI 1120 isolated
amplifier for this purpose. Note this is not suitable for human use.
email me and I can send you info on the issues regarding human use.

The issue with 12 lead is that some of the leads are referenced
together in a very specific way.
Lead1=VLA-VRA
Lead2=VLL-VRA
Lead3=VLL-VLA
you can connect these as differential inputs. However the referencing
of the amplifier has to be considered.
The precordial leads are referenced to what is called the Wilson
Central Terminal. Some circuitry is required outside the Amplifier
system to set this up.

For human use we've done projects interfacing 3rd party 12 lead
systems to LabVIEW.  This was done through an ActiveX control we
developed.

If you need references or assistance feel free to contact me at
[EMAIL PROTECTED] or via www.madry.com.au
cheers
Andrew Madry
