    One suggestion we made with a similar request is to record ECG's into audio files so they can be played back.

    What is the nature of the output of your ECG equipment? If it is analog, it can be recorded through a computer's sound card.

    Using a sound card to record ECG is not optimal. As the sound cards is AC coupled. And hence has a cut off around 15Hz. This will remove some of the lower frequency Content of a ECG signal. But if you only are interesting in doing heart-rate calculations. A sound card will work fine.

    This is a ECG complex. As a start. You can repeat a ECG complex every time. And vary the interval between them. This will be a good approximation for a healthy person.

    Many solutions will be able to solve this problem. It is not one solution. Google is your friend. It is better that you do the research. Then come to us for help and comments

    Are you aware that these are commercially made and certified?

    The components are a Mac running GarageBand. Draw the trace, repeat it forever as "music". Done.

    Sounds like you are asking for an electronic ECG simulator circuit that you can feed to a MATLAB program for analysis. Is that the case?
