  The development of a system that would ease the diagnosis of heart diseases
would also fasten the work of the cardiologic department in hospitals and
facilitate the monitoring of patients with portable devices. This paper
presents a tool for ECG signal analysis which is designed in Matlab. The
Hermite transform domain is exploited for the analysis. The proposed transform
domain is very convenient for ECG signal analysis and classification. Parts of
the ECG signals, i.e. QRS complexes, show shape similarity with the Hermite
basis functions, which is one of the reasons for choosing this domain. Also,
the information about the signal can be represented using a small set of
coefficients in this domain, which makes data transmission and analysis faster.
The signal concentration in the Hermite domain and consequently, the number of
samples required for signal representation, can additionally be reduced by
performing the parametization of the Hermite transform. For the comparison
purpose, the Fourier transform domain is also implemented within the software,
in order to compare the signal concentration in two transform domains.
