Two-dimensional Fourier spectrum of QRST integral maps in classification of patients prone to ventricular arrhythmia

Two-dimensional Fourier spectra of QRST integral maps, obtained by body surface potential mapping, were analyzed to identify subjects prone to ventricular arrhythmia, when they have not been identified by extrema count method. The diagnostic performance (84.38%) of the peak value of the Fourier spec...

Description
Summary:Two-dimensional Fourier spectra of QRST integral maps, obtained by body surface potential mapping, were analyzed to identify subjects prone to ventricular arrhythmia, when they have not been identified by extrema count method. The diagnostic performance (84.38%) of the peak value of the Fourier spectrum as a classifier for subjects prone to ventricular arrhythmia showed an improvement of 3.65% over the use of the extrema count method as a classifier.< >
