I'm working on a Holter monitor (ECG data acquisition) which I need to create for my school project. I'm still in the begging phase, so I didn't choose measuring circuit design yet, but I've extensively Googled on them though and found several promising solutions for ECG measuring. However, since I have very little previous experience and limited knowledge, it's really hard for me to compare and make a pros/cons for each circuit. On addition, Holter monitor will have to measure 24+ hours straight, so that brings a couple of limitations to circuit while most of them are designed only for real-time monitoring as far as I know.
One of Google results that I've managed to find so far was also TI Precision Designs: Verified Design Ultra Low Power, 18 bit Precision ECG Data Acquisition System. It really looks thorough, but I'd still rather ask you, since you are much more experienced than me, if that is the solution you would recommend to me or are there any better out there? What expenses am I actually looking at if I choose TI's PDF posted above?
ECG measurements will be acquired with microcontroller and forwarded to phone by Bluetooth protocol (I still don't know which microcontroller would be the best for my case though). The whole system will have to be as small possible while outputting appropriate ECG measurements. Since Holter monitors ECG for at least 24 hours straight, power consumption is another crucial factor here, so ideally 2 or 3 alkaline batteries should suffice.
Any advise would be greatly appreciated. Thanks in advance!
