Hello,
I am a college student taking an ECG from the body, putting it to 3 filters on the SC-2075 breadboard. The filters consist of an instrumentation amplifier to amplify the output voltage of the ECG, a notch filter to filter out 60 Hz from wall, and a low pass filter to filter out any frequencies above 150 Hz. From my filters, i am connecting it to to LabVIEW. My question is: I need to tell LabVIEW the normal parameters of the heart (i.e the normal ranges of the P wave, T wave, ST segment, QRS complex, etc). From this data, we need numeric indicators and we need LabVIEW to tell us the time in milliseconds of each wave or segment. How would one do this? Please help.

Thank you for answering; however, my college only has the regular LabVIEW license excluding the Biomedical toolkit and advanced signal processing toolkit. So I would need to reach my goal without any of these toolkits.

It seems to me that there are several "steps" to your project (it is not completely clear exactly what you need to do, but bear with me ...).
To do the first step, you need to know enough about your signal (and signal theory) to come up with a Sampling Frequency and an appropriate Sample Size (in time, or in samples). To do the second step, look at your data (make a plot of some sort) and think about how you would describe and identify its features. Then write the code.
