    Hello.
    I want to simulate the ecg front end circuit but I dont know how am I gonna feed in the input so that i can get an ecg at the output stage. I found this circuit here on this forum and i am interested in developing it for my forthcoming mini project. The circuit is attached. If I can simulate it using NI MultiSIM ? Also while I was trying to build the same in MultiSIM I was unable to find MCP6002 IC.
    If you guys can help me it would be a big support.

    Use a pulse source of a few uV amplitude.

    The circuit you posted will produce a lot of 50Hz mains hum and other interference on its output because the patient and the wires to the probes pick it up. Most ECG circuits cancel the interference by feeding out-of-phase AC and DC interference signals to the patient's right leg.

    Since this is simulation rather than real life you can use any comparable amp model.
