Coronary Wave Enhancement for Robust Wave Intensity Analysis

Abstract

Analysis of coronary wave intensity is a hemodynamic index that can exhibit the arterial system and working condition of heart. Apart from electrocardiogram (ECG) research it is a new direction of cardiac disease analysis in non-invasive way. However practically it is noisy in nature. To improve its robustness it is required to enhance the wave intensity analysis. In this paper we have taken an approach to enhance the signal using adaptive method. Mathematical concept of wave intensity analysis is done with pressure and velocity parameters. Further noise is eliminated and smoothed using Savitzky-Golay (S-G)filter and estimated. Design of adaptive S-G filter is utilized finally to enhance the cardiac signal. The result obtained using this method found excellent and can be useful for coronary wave intensity analysis.
