Abstract:
In this paper, a standard ECG database (European ST-T Database) is used to analyzed the frequency spectrum of electrocardiogram waveform based on the Welch＇s method of averaging modified periodograms, belonging to the nonparametric model power sepctrum estimation. The final computing results give a general description of the spectral range and the maximal energy segment of ECG waveform, which is helpful to design the hardware circuits of ECG signal extraction and the software algorithm of the waveform recognition such as P wave, QRS wave and T wave.
