This work presents an electrocardiogram ECG data reduction method based on Walsh spectrum double logarithmic quantization. The technique is theoretically justified for a simulated ECG and its practical efficiency confirmed using MIT/BIH arrhythmia database signals. By classifying a “good” compression as one with MSE 0.005 for 1 : 1 spectral reduction, a normal/abnormal ECG mix returned an 87% success rate for waveforms stored with 8– to 11–bit resolution.

Abstract
This work presents an electrocardiogram ECG data reduction method based on Walsh spectrum double logarithmic quantization. The technique is theoretically justified for a simulated ECG and its practical efficiency confirmed using MIT/BIH arrhythmia database signals. By classifying a “good” compression as one with MSE 0.005 for 1 : 1 spectral reduction, a normal/abnormal ECG mix returned an 87% success rate for waveforms stored with 8– to 11–bit resolution.File in questo prodotto:
