ECG – also known as Electrocardiograms, is a recorder that measure and tracking the electrical impulses of heart activity over time.

Why we need an ECG in our home? The reasons are simple as:

    It’s for your own safety – you can keep tracking and alert by your current heart activity at home, especially for those that diagnosed cardiovascular diseases.It’s a fun and interesting project.

    With right guides and support, building a home ECG is simple as ABC, and you should glad you’re found this site.

    Here is the making process for this ECG:

      Firstly, you need to mount the surface into any kind of tin can you want, this for reducing the interference.After it, Shield the audio cable for the electrode leads and make sure the braiding is earthed to the tin.Connect the three blue wires of the leads to the RCA plugs.

      The biggest challenge for this homemade ECG is how to eliminate the 50Hz interference successfully. By overcome this problem, a 50Hz notch filter should be a great helper, which it will reject the 50Hz hum, without even affecting the shape of the wave.

      However, there might still plenty of improvement for it.

      They’ve found a better solution and you will spot it at the second generation of ECG.

      The brand new Second Generation’s ECG might cost you some bucks, but it is much more worth than the first generation.

        In the beginning, go and search for a used ECG. It mainly cost you about $10-$15.Then, you will manually modify and convert it to plug to your computer.

        This new ECG is much better than the older, as the noise interference has greatly reduced.

        You should build an ECG and feel the fun and exciting moment. [link]
