Real-time Signal Processing of Data from an ECG

This paper explores the software and hardware developed for real time process and analysis from an Electrocardiogram ECG. The portable ECG device is used to capture data from the heart and lungs which is automatically converted from analogue to digital signal for further analysis. Via the use of an ECG device, data is collected at two different speeds i.e. walking and running respectively. The collected data is retained on PC/laptop and stored on cloud for further analysis. Important frequency components of the time samples of data collected are synthesized and then demonstrated with a simple MATLAB program. Data will be tabulated on MATLAB and analysed using a variety of simple MATLAB functions and a range of plots will be generated. Results showed during the state of walking, the amplitude of the heart rate was consistent. The sudden decline of amplitude and the recovering back to normal implies the change in heart rate due to the fact the subject is running. Plots generated are analysed carefully and judgmental decisions are made on the outcome.
