Heart Rate Simulator Using LabVIEW and DAQCard Analog Outputs

[testdesign]

I am looking to simulate a Heart Rate signal using LabVIEW DAQCard Analog Outputs.  I imagine if I send a digitized recorded ECG signal from a file and use LabVIEW to output this data from the Analog Output of the card that would simulate it.  Does anyone know if this has been done before and if it is even practical?  Thanks.

Look out for hardware-timed DAQ AO cards with large enough FIFO, so that you can load the ECG waveform to memory and let it run in repeat and also the resolution + range.

Seem completely feasible - DAQ cards just generate the voltage you tell it to (within hardware specs) and don't care what type of waveform it is.
