A Review on IoT Based Health Monitoring System

Today, heart disease is considered one of the leading causes of untimely death. Thus, engineers have developed a variety of therapeutic devices to diagnose and evaluate various diseases. Health care has become one of the most important issues for both individuals and governments due to rapid population growth and medical costs. Many patients suffer from cardiovascular complications that cause serious threats to their health, so they need constant monitoring with a traditional monitoring system such as Electrocardiographic (ECG) which is a very important method used to measure cardiac output, this procedure is available only for the most expensive and remote hospital for remote patients. The development of wireless technology enables the construction of a network of Internet-connected devices. The proposed ECG monitoring system consists of the AD8382 ECG sensor for reading patient data, the ESP8266 Wi-Fi control module, and the IoT Blynk application. The implementation of the proposed ECG health care system enables the physician to monitor the patient remotely using the IoT Blynk program installed on his smartphone to monitor and visualize the patient's ECG signal. The monitoring procedure can be performed anytime and anywhere without the need for a hospital.
