IoT Based wearable ECG monitoring system for Patient Emergency Condition

This project presents a wearable Tele-ECG and heart rate (HR) monitoring system with an innovative architecture designed for real-time remote healthcare monitoring. The system incorporates a stretchable singlet embedded with textile electrodes (TEs), along with textile threads, snap fasteners, Velcro, sponges, and an ECG circuit for accurate biosignal acquisition. Additionally, smartphones, server, and web interface are integrated to facilitate seamless remote monitoring. To evaluate the effectiveness of the TE-based ECG system, an SMS-based ECG transmission mechanism has been implemented, achieving an average correlation of 99.23% between the recorded ECG signals. The system accurately plots ECG signals, calculates HR with a mean absolute percentage error of 1.83%, and displays the data in real time. The recorded ECG data is transmitted to a server, enabling physicians to analyze patient signals remotely via a web page or smartphone. For enhanced patient safety, the system includes an automatic alert mechanism. If the HR exceeds normal limits or the user presses the "HELP" button on the smartphone interface, an instant SMS notification is sent to the physician. Simultaneously, the system activates a flashing LED for additional alerting. This fast, uninterrupted telemonitoring system improves patient care and psychological reassurance, making it a promising tool for remote cardiac health management.
