Micro-ECG-monitoring system based on arduino with bluetooth feature

Abstract

Cardiovascular disease (CVD) is one of India's most deadly diseases, with a 4.77 million annual death rate in 2020 [1]. CVD rates have risen from 1.6 percent to 7.4 percent in rural areas and from 1 percent to 13.2 percent in urban areas [1]. Electrocardiogram (ECG) devices, which monitor the heart's activity, are far too expensive to be used for personal care. In this project, we created a low-cost device using an Arduino (UNO/MEGA) microprocessor and a Real-time ECG graph display feature. The main instrument for measuring the pulse is the AD8232 sensor, which converts the sense-voltage obtained from ECG electrodes placed on the body. Integrating Arduino microcontroller (Uno/Mega) and Bluetooth module HC-05, the ECG readout may be presented on a mobile phone's monitor in real-time 24x7. The ECG simul externally attached can provide the accurate 12-lead ECG that depicts the patients' current health status in real time. This portable ECG has produced a satisfactory outcome in terms of production costs.
