Microcontroller for ECG (Holter monitor)

[krneki]

Since I have very little previous experience with microcontrollers, I'm looking for an advice on which microcontroller to get that will be appropriate for Holter monitoring (ECG signals from external circuit with 3 channels)? It should be as small as possible with low battery usage (because of for 24 h+ monitoring) and good enough performance for ECG application. As far as connectivity goes, I will use Bluetooth and maybe Wi-Fi, but Bluetooth is crucial for sure. Are there any suitable microcontrollers with Bluetooth integrated or would I have to pair it with external BT module? If that is the case, which combination would you then recommend to me? 

 

Any advise would be greatly appreciated! Thanks

If your trying to do the mini project to moniter the the heart rate, Arduino uno microcontroller is enough , with HC-05 bluetooth module.  With these heart rate values monitoring is possible in android mobile. By using Bluetooth serial control software.
