This study undertakes Time-frequency characterisation of Ventricular Late Potentials (VLPs), To represent the VLPs introduced to the late phase of the QRS complex some models that also contain nonstationarity have been proposed. Time-frequency analysis of the ST segment that VLPs have been added overcomes the information that is lost when one dimensional techniques were used, Due to uniqueness of Wigner-Ville distribution it has been chosen as basis for this analysis. The results were found promising in both qualitative and quantitative sense.
