First steps to program for 12 lead ECG

[fredjmartins]

Greetings,

I've done a project of a ECG Labview program with 1 lead with 2 electrodes (very simple one), but now I need to start working on a program to acquire the 12-lead with 10 electrodes.

My knowledge with labview is very basic and I've figured out that 12-lead project is starting to be a bit complex to me and I'm writting to ask for a little help to know how to start, specially with the electrode connection and channel configuration.

To difficult my job I have no biomedical toolkit (only signal processing toolkit).

I'm using the ni-DAQ 6212.

Sorry for being a little vague in explainning what I'm asking, but I'm at the point that don't know where to begin.

I thank all the help that anyone can give

Thanks,

FM

Hi,

I check 6212's spec. It has 16 analog input channel (400KS/s). I think this device is okay for 12 lead ECG acquisition. But you need to consider the pre-amplifier, isolation on your own.

Here is a ref deign using NI SBRIO and Texas Instruments frontend. For your reference.

Thanks!

Thank you for the help.

Not wanting to become anoying... and what solutions I have about the einthoven triangle and the driven right leg? The same electrode being both positive and negative (depending on the lead) in the fist and the insertion of voltage based on the other electrodes realimentation. (I've figured out that probably I will need an output based on the others inputs... I think)

Thanks again for all the help you can give me.
