Heart Rate

[Bildavid]

Hi all,

I am working on an ECG project for my thesis . I have implemented the hardware and I am acquiring the ecg signal through serial port . I did that all and i am having a signal that is displayed . now i need to go further with the project and add some heart rate indicator to it . 

I need a sample VI that i connect the ECG signal to, and then extract the heart rate from it . 

can you guys help me with this ?

Regards .

Hi Blidavid

Sounds like an interesting project!

It depends on what you're passing into the serial port, you must have already digitised the signal?

We do a biomedical toolkit which can work with and extract data from ECG signals but it's intended to be used via NI DAQ hardware.

See the ECG Feature Extractor VI

Kind Regards

Dear friend ,

thank you for the very fast reply . 

yes i have digitized the signal using the microcontroller PIC ( 16F874) from microship .so i am sending diitized values to the serial port . 

well . talking about the biomedical toolkit and DAQ , I am not using them at all . and this is the challenge . to get a real ECG signal through serial port . 

I am having real ECG signal that is displayed yet . but wanna do further .

can you suggest anything ?

thank you .

Hi Bill

Have you read this paper on using LabVIEW for ECG Signal Processing?

I suggest that you don't try to re-invent the wheel but if you don't want to use the biomedical toolkit then you should at-least download it and open up the ECG Feature Extractor VI (just double click it) to see how it works - you should then be able to implement something similar without actually using the toolkit.

Kind Regards
