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.

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.
