LabVIEW
ecg
Are you looking for a way to simulate the 50/60 Hz noise from the mains? Then you just add a signal to your simulated ecg. In this thread you will find link to a ecg simulator doing this.

First of all. The code you copied from marp84 has some major flaws. It is stupid. I have cleaned up and removed most of the bad programming. I have also removed the "elapsed time.vi" You do not need it. Your timing is handled by The daq hardware. As an example if you run your program, and set the sample rate 1000, and then read 1000 samples every time you will get 1 second of data. This data will come in a continuous stream.
As mentioned before you need ca 3 to 5 seconds of data for calculating HR, But you can have a update every second. So we need some type of FIFO memory. The good thing is that we already have placed it on the block diagram. The waveform chart! But we need to set how many samples we shall store in the FIFO. Find charts and history length in help
About filters. If your unit has analog filters you can probably skip filters for now. But you can add filters later then things are working.
For getting started set the sample rate to 1 Khz and read 3-5 seconds of data every time. If I see some useful code I may help you more. But I will not answer questions asked because you are to lazy to look in labview help, or search trough examples. You may learn a lot by looking at the labview examples.
