Holter Electro Cardio Graph (ECG)

Project Description:

This project implements Holter ECG device with on board non-volatile flash storage capable to store up to 10 hours of ECG graphs. It connects to host pc through USB port or Bluetooth adapter to dump ECG data to a PC file. It runs on two AA battery for long life cycle. 16 bits micro-controller  gives power to detect anomalies on the fly.
