    ECG from Physionet.org

    hi all,

    Please i need to know if the ECG data obtainable on physionet.org contains noise, or has been filtered....

    I downloaded an ECG file from the PTB Diagnostic ECG database(ptdb), and am trying to plot it using
    Visual Basic, but my plot does not look like the one on the website...please what do i do?Click image for larger version.

    Re: ECG from Physionet.org

    Signal in ATM wiever on phisionet.org shows the result that You should obtain. It is a reference. The description of that DB is laconic. Probably it is 16 bit per channel, but I can't find informatin about byte order i.e. the signal can be ordered byte0 byte1 or byte1 byte0.
    The most populad DB is an MIT-BIH Arrythmia Database. The coding is little bit more complicated than 16b/channel, but is well described on Phisionet.org
