There has been a discernible increase in a number of health-related problems in recent years, which has led to the need for creative solutions that support early identification and treatment. Healthcare solutions built on the Internet of Things (IoT) have become an essential tool for early medical condition identification and remote monitoring. These devices can continually monitor vital signs like body temperature, heart rate, blood oxygen levels, and ECG signals. They can also give medical experts real-time feedback so they may take appropriate action. Health data collection and transmission are made easier by smart medical equipment that are linked to smartphone apps. Modern healthcare technology guarantees timely medical attention, which enhances patient outcomes and lengthens life expectancy. This study introduces an Internet of Things (IoT)-based realtime remote patient monitoring system that protects the integrity of electrocardiogram (ECG) readings. To send ECG data to a centralized web server, the system uses the Message Queuing Telemetry Transport (MQTT) protocol. Healthcare practitioners can use PCs or cellphones with the web interface to view both historical and real-time ECG data. Effective data collection, storing, and analysis are made possible by the integration of smart devices, which lessens the need for manual intervention and permits the monitoring of several patients. Therefore, by giving medical staff precise, up-to-date data, the system improves the quality of healthcare services.
