Standard Electrocardiogram (ECG), only records the patient’s heart electrical activity for a short duration and the patients are not encouraged to move throughout the recording process. However, abnormality may not occur during this period. Therefore, there is a need for a portable ECG device, also known as Holter monitor, which provides good accuracy and comfort, to record ECG while patient is carrying out daily activities. This report documents the research and design of a low power Holter monitor for detection of arrhythmias. The first part of the report includes literature review and research on the understanding of heart electrical activity and the different types of arrhythmias. In addition, research conducted on the interference that may affect the recording of Ambulatory Electrocardiogram was also presented. The next part of the report involves the methodology of designing and construction of the hardware. The hardware design involves the use of low power components, and encompasses different noise cancellation techniques. The software design optimizes battery life with the help of a microchip, analysis the ECG signal detected and decide on the activation of wireless module. Finally, the last part of the report presents the conclusion and also the future recommendation for this project.
