Inverted ECG signal solution

[NainaSarda]

Hello!

I have been trying to acquire an accurate ECG signal using DAQ. After implementing noise removal methods like using filters, I'm getting ECG signal which has ALTERNATE CYCLES INVERTED.

I have attached the VI file and the screenshot of the output.

I will be grateful if anyone provides a solution to this problem.

Thank you.

Hello!

I have been trying to acquire a real time ECG signal using DAQ. After implementing various noise removal methods like using a filter, I am getting an ECG signal having ALTERNATE INVERTED CYCLES.

I am attaching the VI file and the screenshot of the output. I will be grateful if anyone provides a solution to this problem.

Please! help!

Thank you.

I am working on a project on aquiring ECG signals. I am getting the output with ALTERNATE INVERTED cycles. So I want to put a full wave rectifier at the output in order to get all the cycles. can you please help me with the solution how to do full wave rectification at the output?

Hi Naina,

please keep your discussion in one place! We don't like to discuss the same problem in 3 threads in parallel…

Signal can't be right.  It's unipolar 0 to 2.5V and clipping on both ends.  Too much signal.  If you disconnect or ground the input I'd expect it to go mid-scale at 1.25V.  So reduce the gain, subtract 1.25 from the data and then run it through your filter.

Good luck,

David
