ECG BPM Calculator

[chuck25]

My LabView programming experience is very limited, and I need to develop a VI that can take in a real ECG signal (that has noise) and measure the beats-per-minute (BPM) by detecting the QRS-wave. I am restricted to not use an amplitude-detector to detect the QRS wave--I must detect it somehow by the slope. I've looked at the forums, and I've read the reviews, but the closest I've seen to a VI that does what I need is attached to this post. Thank you very much for your help.

chuck25,

Have you checked out our Biomedical User Group? Within that group there are documents called, "How to use NI Biomedical Startup Kit 2.0 - ECG Feature Extractor" and "How to use NI Biomedical Startup Kit 2.0 - Analog ECG Signal Generator". These documents use the NI Biomedical Startup Kit 2.0, which you can download here. Also, there is a tutorial on our website called "LabVIEW for ECG Signal Processing". This forum post might also be of some help.

Though I am not familiar with this toolkit, hopefully some of these resources will be of some help to you.

Can you use the peak/valley detection function? Goto help in the toolbar. Then select find examples and serach for peaks. Use the "Peak Detection and Display.vi"  It even has a "ECG" signal as signal source.
