P- and T-wave Characterization in the Presence of U-wave in Electrocardiogram

Abstract

Abstract

Even after being noticed around a century ago the U-wave has not been studied much as compared to the other waveforms of the electrocardiogram (ECG). In this proposed work the effect of presence of U-wave on morphology of P-waves and T-waves has been studied. Characteristics of P-waves and T-waves from ECG beats with an U-wave has been compared with the P-waves and T-waves from ECG beat with an U-wave. Arithmetic mean, standard deviation, peak to peak value, skewness, and kurtosis of the corresponding waveforms has been extracted for the comparison. T-waves were found to be affected more compared to the P-waves due to the presence of a U-wave.

Keywords: Electrocardiography (ECG), P-wave, T-wave, U-wave
