Method and Device for the Determination of Murmur Frequency Band

摘要

The present invention is related to a method for the determination of frequency band characteristic of a heart disease comprising the steps of: recording a first set of phonocardiograms from a first set of reference healthy patients, and a second set of phonocardiograms from a second set of patients suffering of said heart disease; calculating spectral energies of all possible frequency bands; comparing said spectral energies of all possible frequency bands for determining an optimized frequency band giving rise to the maximal distinction between spectral energies of the phonocardiograms from first and second set of phonocardiograms.
