Fisher classifier in diagnosis of coronary heart disease

Abstract

This paper designed a analysis system of coronary heart disease which can analyse the signal of heart sound and extract the feature of it. We apply the method named HHT (Hilbert-Huang Transform) to analyze the signal of diastolic heart sound, and classify the results that have been dealed with the initial signal using the Fisher classifier. And determine the test's blockage level of coronary artery ultimately.
