Low-Cost Portable ECG Monitoring Device for Inaccessible Areas in Pakistan

Abstract

The need for a constant health monitoring system is essential especially for cardiovascular disease (CVD) that may cause sudden stroke or even death. In this paper, we present the design and development of a low-cost, efficient, and user-friendly portable Electrocardiography (ECG) monitoring device. Most of the existing heart rate measurement devices and tools available in underdeveloped countries like Pakistan are quite expensive, far to reach and inaccessible in most of the rural areas especially for the female population to reach the healthcare centers. Our proposed device monitors the patient’s body information using three lead-silver chloride ECG disposable electrodes and detects the pulse signal. The detected heart pulse signal is first filtered and then amplified. The device can display the heart signal on an external PC/laptop Graphical User Interface (GUI) and the digitized pulse rate on a Liquid Crystal Display or (LCD) to detect any signs of abnormality. We have evaluated the device on several trial subjects. Finally, the results were compared with the standard ECG signal. Our device measures the pulse signal with good accuracy like commercial devices with higher costs.
