1. A method for detecting abnormalities of heart having a time varying QRS signal, said method comprising the steps ofpartitioning said QRS signal into a sequence of time displaced time segments,transforming said time segments into respective sets of spectral components, andcorrelating said sets of spectral components across the QRS signal, andgenerating an abnormality score when the correlation of said correlating step is above a predetermined state.
