Defective Heartbeat Detection

Abstract

In this project, the aim is to detect the defective heartbeat by a non invasive method. Preliminary detection of the heartbeat can help in various stages afterwards and can lead to high performance heart diagnostics. The first subsystem is based on the relationship between the electrocardiogram (ECG) and phonocardiogram (PCG) signals. The relationship between both signals is determined as an impulse response (h(n)) of a system, where the decision is made based on the linear predictive coding coefficients of a heart’s impulse response. The other subsystem uses a phase space approach, in which the mean squared error between the distance vectors of the phase space of the normal heart and abnormal heart is judged by the likelihood ratio test (Λ) value, on which the decision is made
