how to make ECG circuit using arduino uno

Question

i want to mke an heart attack device using arduino uno, does any one have any idea how to make an ECG cirrcuit and how to analysis the digital data of CEG

There are a few ways to do the circuit, you can use a design like this or try one like this from TI. All the designs use a similar set of components, the leads to go on the person, a mux to connect all the leads into the amplifiers (Lots of leads and you only use a couple at a time), the amplifier itself (Ideally one designed for such a purpose due to things like noise), the Analogue-Digital converter (Depending on how accurate you want it, you'll want to look at the resolution of the ADC, the higher it is the better), and the processor. Depending on your specification, an arduino uno might not be enough to handle it (The onboard ADC for example could be a limiting factor) you may need something like an arduino mega, or another ARM core device. You will have to experiment and see what works best for your project. To analyse the ECG, you'll need a decent algorithm to do it, you can find a lot of information on these online. You could try to implement these on your microprocessor, or you can send the data over USB to your computer and analyse it. Much of the information for making your own ECG is around online, just remember it will be limited in it's uses, so no trying to use it the same as a hospital's ECG
