I know the EKG signal (sorry, ECG - I'm old school, they started with the German abbreviation and I forget to say ECG now) doesn't have a very wide bandwidth, so will fit fine in an audio signal.  You can use any device that will transmit audio over WiFi such as a Raspberry-Pi (rPi) or perhaps a much smaller and lower power single chip device like they sell for Bluetooth, but with WiFi instead (I think I've seen these on eBay, but not certain).  An rPi-W is pretty small even if it needs a hundred mA or so to power it.

I was going to say you won't need to use an ADC chip but the r-Pi only has a single channel of ADC.  So maybe you'll need your ADC chip, I expect it has some specialized hardware to make the other needs easier to design.

I don't know that they actually use much less power than an rPi-W but they should.  They will be a little harder to program than an rPi, but a lot of the grunt work has been done in terms of getting started.  The ESP-8266 in particular has quite the community even if nothing like the rPi.  I don't recall what they have for analog I/O, but I think it is at least multichannel if not any more precision than 10 bits.  So you might still be using your ADC.

Thank you for catching that.  I meant the ESP32.  This is a faster dual CPU with encryption hardware, but from the same folks as the ESP8266.
