Cardiac-Net: A Wearable ECG Prototype and Hybrid CNN–Transformer Model for Atrial Fibrillation Detection in Long-Term ECG Recordings
Postoperative atrial fibrillation (POAF) is a leading cause of stroke and mortality after cardiac surgery, motivating continuous long-term ECG monitoring.This paper presents Cardiac-Net, a wearable ECG system (ESP32-S3/AD8232 BLE device with a Flutter mobile gateway; 128 Hz nominal/85 Hz effective BLE sampling rate, 12...
