Raw Waveform ,Plz advise

[huh]

To know how to design a suitable vi to acquire ECG waveform from the bio-amplifier board using LabView program.

[Sarah Thompson]

Huh,
Here's a VI I wrote in school to acquire ECG signals using an NI DAQ board. Hopefully this will help you get started with your application. Have a great day!

Hi Sarah

I am intrested in acquiring and analysing ECG waveform .I was unable to run your vi. I have a 8.0 Labview version and a NI PCI 6259 card . Do i need to configure my PCI card to run your vi . Please advise me how can i view the waveform and analyse from the ECG vi you have already built .

Jim,

Your card uses DAQmx instead of the older Traditional DAQ driver that Sarah's code uses. I modified the code to work with your card and also converted it to LV 8.0.

i really appreciate your advise and help ,but even after connections i am not able to see the raw ECG waveform . Do i need any more drivers or do i need any more configration upgrade.Please do advise .

Jim,

I changed the code a little more, it seemed like the graphs were plotting black lines. You will also need the new DAQmx driver to perform data acquisition.

i really appreciate your advise and help , i was able to view the wave forms .Please advise me how can i view a clear wave form, i tried various combinations of frequency and sample rate still i am unable to get a clear wave form . Can you please aprize me with your settings if you are able to view a clear waveform .

Jim.

Jim,

I am not sure what you mean by a clear waveform. Can you elaborate with some pictures?

Please advise if we can do signal conditioning by using a lowpass filter and then a band pass filter to the raw ECG signal .Will it improve my waveform ?
