Detection, real time processing and monitoring of ECG signal with a wearable system

In this study, applications in the field of monitoring of Electrocardiography (ECG) by using wearable system technologies are summarized and discussed. It is also explored a new solution for real time ECG monitoring with low power DSP and different type of real time signal processing methods. With this system, a lot of data can be collected and compared to determine the coming problem for the heart diseases in the future. In addition, a sample wearable system application is realized for processing and monitoring of ECG signal in real time. The system is mainly composed of three parts. First one is patient vest that carries the ECG electrodes and the main board. Second one is designed for main board hardware that senses heart signal from the body, and then to amplify and convert it from analog phase to digital. The final part is developed software that monitor and record obtained signal cooperation with computer by using DSP software which will processing and transmit the signal. In this study, some of the signal processing techniques such as band passing FIR, IIR notch and adaptive filter were used. Code Composer Studio V4 (CCStudio V4) software environment is used to embed the developed software into the DSP. In order to trace the signal with computer and to save the obtained data with .dat extension, QT program is used which is mostly used for mobile applications. As a result, perception of signal by patient's vest, conversion to digital phase and processing by high level signal processing methods are satisfied. In addition to this, real-time processing is succeeded with high speed without any delays.
