Heartbeat Analyzer: Low-Cost PC-Based ECG Machine
Abstract: This project presents the design and development of a portable, real-time, PC-based ECG monitoring device that addresses several critical issues faced by traditional monitors, such as baseline wandering, muscle noise, changing electrode resistance, and lead problems. These challenges typically decrease the reliability of ECG systems. To overcome them, we employed high-gain instrumentation amplifiers like AD624AD and AD620, which improve the real-time processing of ECG morphology and ensure power-efficient performance. The system captures the ECG signal, transmits it via the computer?s parallel port, and displays it across three separate lead graphs using custom software. Reliable detection of R-peaks is achieved through multiple statistical techniques, ensuring accurate heart rate measurement. The system identifies R-peaks within a defined time and amplitude range and uses the average RR interval to determine heart rate. Additionally, energy consumption and battery life were evaluated using a profiling environment, providing valuable insights into the system?s efficiency. This environment includes a PC, digital oscilloscope, and other testing tools to measure and improve performance.
