Single Wireless Electrocardiogram Monitoring and Acquisition System (SIWEMS)

Cardiovascular disease is the main cause of human casualty in the world as reported by World Health Organization (WHO). To facilitate in minimizing this cause, constant monitoring of the heart´s rhythm appears to be essential in observing the condition of the heart by checking or recording the Electrocardiogram (ECG) signal. This paper presents a prototype design of Single Wireless Electrocardiogram Monitoring and Acquisition System (SIWEMS). The system is designed to implement Zigbee wireless technology for monitoring and storing an ECG signal remotely from a patient. The conceptual design of the system is discussed along with the circuits devised to generate a good-quality signal. Microcontrollers are employed to form a controller board for digitizing the signal and stored the signal in SD-card. Plus, the board is also interfaced with wireless module to transmit the signal to a Graphical User Interface (GUI) window. The GUI installed in laptop received the signal and concurrently displays it in real-time. Instead, the window does also provide data logger function. The proposed system is tested, and the results demonstrate it performs well to generate, displays and logs the ECG signal. Currently, this prototype is practically relevant to be employed for remote continuous dynamic monitoring and acquisition of ECG in healthcare.
