Wavelet Analysis of Electrocardiograms

: Some electrocardiograms, e.g. electrocardiograms recorded in patients with atrial fibrillation, myocardial infarction, or receiving some medications, contain waves of small amplitude. Despite low amplitude, these waves can significantly affect correct identification of the pathological process and diagnosis. The approach proposed by us allows studying these small waves using the wavelet analysis by constructing the corresponding wavelet image of ECG using special software. Two examples of construction of wavelet images of ECG in atrial fibrillation and myocardial infarction are presented.
