This project presents the design of a low-cost, portable 6-lead wearable ECG system for patient monitoring in High Dependency Units (HDUs). Using the AD8232 signal conditioning IC, ATmega328P for processing, and ESP8266 Wi-Fi module for wireless transmission, the system acquires six ECG leads (I, II, III, Avr, aVL, aVF) and displays real-time waveforms on a web-based dashboard. ...
