A Portable Android Based ECG System for Long-Time Heart Monitoring

Electrocardiogram (ECG) is a very powerful medical device, especially for heart related issues. It helps to understand how the heart works, and gives a helping hand in diagnosis of heart related problems, which is becoming very important in modern era. In this paper, we are proposing a portable android based device which is capable to store ECG signal through wireless medium for a long time for predicting the heart related artifacts and also to act as a prior warning system for the user. We are going to implement using Arduino Uno and HC-05 for bluetooth communication to make it portable and wireless. And we are using a SD card to record the real-time data which can be used to diagnose a disease or arrhythmia. It can display the real time ECG in the smart phone to the user, by the help of an android app made using MIT app inventor.
