Hello again ;
I need to finish my design but I need some technical supports as possible as you can and thank you in advanced.
Our design depends on ADS1291 to detect ECG signals and classify them . We would use only 2 leads there is no RLD lead . But I still need support with some issues.
1. I would use DC leadoff detection but I am using only two leads electrodes , so I cant block DC , what do you suggest a solution ?
2. I Have to measure the impedence of the body (resistive) the imperence between the two electrodes I could not find anything about this in the datasheet; please could you explain how to acheive that.
3. I have to detect PACEMAKER activities; hardware detection would be better but also could you suggest an example circuit to be added to ADS1291 ; know that i am using unipolar power supply (0-3.3v).If not hardware any example for software detection ?
4.Does anyone have an opensource ECG classification algorithm?
Thank you inadvanced
In reply to HECTOR:
New Issue ;
I am trying to read the ECG again and again ; as I told the reading are ok ; but there always an offset voltage added to the signal and this offset voltage not fix to subtract it each time ; some times it about 0.01V somtimes it goes to negative , Do you suggest a solution ?
Should a pull up resistors to AVDD to the inputs helps to make this offset fix ?
