Tomographic representation of ECG-signal

We consider signals of an arbitrary nature in the tomographic representation and compare their tomographic representation and the fractional Fourier transform. Also we illustrate how to apply the tomograms and the identical Radon transform for processing medical electrocardiogram (ECG) signals. The first results obtained show that, in contrast to routine Fourier analysis, the Radon transform revealed additional information for patients with early signs of ischemic heart disease (IHD) compared to healthy persons.
