Implementation Of Signal Processing Filters For Portable ECG Devices Using Android Mobile Phone And Bluetooth

ECG is the primary tool for the diagnosis of all the cardiovascular diseases. This paper proposes an android application based ECG monitoring system with software filters. The ECG monitoring system comprises of mainly three subsystems. The first subsystem which consists of the front end ECG module is dedicated for the extraction of the sampled ECG signal values from the patients. The second subsystem consists of a micro controller and Bluetooth module which enables the transmission of the sampled data to the android mobile phone. The third subsystem is the android application which processes the ECG signal and plots the graph on the mobile phone screen. The filtering and smoothing of the ECG signal is done in the android application.
