offline heart rate extraction from ECG signal

Post by mbinder » Sat Aug 09, 2008 5:14 pm

I have acquired raw ECG signals with EXG electrodes and now I'd like to extract /convert them into HR values.

Do you know any NI VI or any easy-to-implement algorithm for an offline HR data extraction from analog ECG data acquired with BioSemi ActiveTwo?

Any help greatly appreciated! :)

A VI to calculate the heartrate from 2 EX channels is available for download from , I have written this VI a few years ago for online heartrate calculation (was included in some custom versions of ActiView), but you can of course use it in off-line applications just as well.

I had quiet the same question as mbinder. I acquired ECG signals and are now trying to calculate them into HR values. Since I never used Labview before, I have some problems in reading and usign the VI. Is there a "how to" or sth similar I could use.

kind regards

You can also use EDFbrowser to extract heartrate values from raw ECG-data.

Hi Coen,
The HR value you mentioned is heart rate variability? and how to use the VI to extract? Thanks in advance.
