HeartGuard – ECG Anomaly Detection Device

Reduced-lead real-time arrhythmia detection PCB with ADS1298 + STM32F411 + BLE

Custom 4-layer PCB for real-time ECG acquisition and arrhythmia detection, reducing clinical leads to 2–3 using the Einthoven triangle.

  • Designed analog front-end using TI ADS1298 (8-channel, 24-bit ECG AFE) with custom signal conditioning for real-time arrhythmia detection
  • Developed 4-layer PCB in Altium integrating ADS1298, STM32F411 (Cortex-M4), and BLE module for wireless data streaming
