ECG signal amplication

Former Member
Former Member
11 May 2014

Good morning.

I just received my Raspberry Pi. I am a very very beginner, with some knowledge in programming, trying to learn JAVA but a dummy in electronics.

Could someone tell me how to amplify an ECG signal so that it can be "seen" by the GPIO? Between 1 and 5 mV.

Thank you very much.

    Be very careful using devices like RPI as ECGs. There are strict standards for medical equipment connected to the mains, even via PCs, USB or power supply bricks and it is unlikely that the typical cheapo…

    I don't want to be a total PITA but you are replying to a 7 month old post with a link to a paper which can only be accessed by paying money. What am I missing here ? MK

    Weird - the link you have inserted has nothing to do with cyber attack but is to a basic magazine article summarising electrical specs that medical devices should meet - was this a mistake or have I missed something (again image).

    BTW - your US-centric bias is showing a little - the FDA is a US only authority - in other places we have other authorities.

    Do you know of any actual guidance issued by the FDA or others (rather than rules) ?

     

    The OP (who last logged in more than 7 months ago) seemed to be interested in a home build kind of thing - he doesn't need to worry about the FDA - just about staying alive.

    Design and development of medical devices should be according to the guidance of FDA. It will ensure you about good quality of medical device which will never fail during real use. There are frameworks given for manufacturers to develop and implement design controls. However, most important concern to look out is the medical device security from cyber attack.

    Be very careful using devices like RPI as ECGs. There are strict standards for medical equipment connected to the mains, even via PCs, USB or power supply bricks and it is unlikely that the typical cheapo USB power supply used with an RPI will comply. These standards are to ensure the safety of people connected to medical equipment. The very good and direct electrical connection the ECG probes make with the "patient" make the risk of electric shock much higher than for someone just using a normal device held in their hand.
