Promising low-gate-count ECG encoder for wireless sensors; leaves open clinical validation and real-world deployment.
The proposed VLSI design for a lossless ECG encoder achieves high compression rates with low power consumption and hardware cost, making it suitable for wireless body sensor networks.
Chen et al. (2013) studied Arrhythmia. Lossless ECG encoder VLSI design vs. Previous low-complexity and high-performance lossless ECG encoder studies was evaluated on Average compression rate. The proposed lossless ECG encoder VLSI design achieved an average compression rate of 2.56 for the MIT-BIH arrhythmia database, with lower power consumption and hardware cost than previous designs.
