Abstract
In this paper, a compression method for electrocardiographic (ECG) signals is proposed. The proposed method is based on the spectral content variation of each cycle of the ECG signals. The fast Fourier transform (FFT) is used as the signal spectrum estimator. The proposed method allows the entire reconstruction of the ECG waveform signals from the compressed data, keeping all relevant information present in the original signal for further diagnostic analysis and processing. In order to show the credibility of the method, a visual inspection by a cardiologist was done on the reconstructed signals.
