Why the study?
Classical sensor-based AF detection requires continuous transmission of ECG signals to a remote server, rapidly exhausting sensor energy and shortening device lifetime.
A novel embedded AF detection scheme for wireless body area networks achieves high accuracy while saving 93% of energy compared to continuous transmission.

Enables energy-efficient local AF detection in wearables; leaves open prospective validation before clinical adoption.
Wireless body sensor networks (WBSNs) and wearable technologies are the new trends in healthcare applications. This technology can provide real-time monitoring of the patient's biosignals and health condition. In this context, the analysis of ECG signals, reflecting the heart activity, is considered as the key tool in diagnosing cardiac disorders such as atrial fibrillation (AF) that can lead to strokes and heart failure. Classical approaches for sensor-based AF detection require continuous transmission of ECG signals to a remote server, which can rapidly exhaust the sensor energy and shorten the lifetime of the application. In this paper, we propose a new low-power scheme for AF episodes detection in ECG signal that is intended for implementation in WBSN. The paper details the design of this scheme and demonstrates its high accuracy for AF detection and shows that it saves 93% of energy.
