Electrocardiography (ECG) is an important diagnostic tool used to monitor life-threatening Cardiovascular (CVD) diseases. In Bangladesh, many people in rural or economically poor regions cannot afford the high healthcare costs of ECG due to the use of very expensive, classical, bulky ECG systems; thus, regular diagnostic service for such areas is out of reach, which makes early detection and continuous monitoring of CVDs quite difficult. This work, therefore, develops a wearable, portable, and cost-effective ECG device to make ECG monitoring affordable for the unprivileged rural people. The proposed device consists of an ECG module, microcontroller (Arduino Nano), Wi-Fi component, and OLED display to allow real-time local visualization and remote monitoring using cloud services. The device uses recent wearable technology that can offer continuous and non-invasive measures of ECGs in nonclinical settings. The suggested system shows a good combination of hardware design, signal processing, and connectivity, providing a low-cost, reliable, and portable system to monitor the ECG continuously.
