Cardiovascular diseases currently pose the highest threat to human health around the
world. Proper investigation of the abnormalities in heart sounds is known to provide vital …

Most heart diseases are associated with and reflected by the sounds that the heart
produces. Heart auscultation, defined as listening to the heart sound, has been a very …

This second edition of The Illustrated Wavelet Transform Handbook: Introductory Theory and
Applications in Science, Engineering, Medicine and Finance has been fully updated and …

Heart rate classification is a challenging problem primarily due to spectral overlap of normal
heart sound with internal sources like extra heart sounds, extra systole, murmurs, respiration …

Wavelet packet transform decomposes a signal into a set of orthonormal bases (nodes) and
provides opportunities to select an appropriate set of these bases for feature extraction. In …

Auscultation of heart dispenses identification of the cardiac valves. An electronic
stethoscope is used for the acquisition of heart murmurs that is further classified into normal …

The features extracted from the cardiac sound signals are commonly used for detection and
identification of heart valve disorders. In this paper, we present a new method for …

Assessment of heart sounds which are generated by the beating heart and the resultant
blood flow through it provides a valuable tool for cardiovascular disease (CVD) diagnostics …

Fetal phonocardiography (fPCG) is receiving attention as it is a promising method for
continuous fetal monitoring due to its non-invasive and passive nature. However, it suffers …

In order to assist the diagnosis procedure of heart sound signals, this paper presents a new
automated method for classifying the heart status using a rule-based classification tree into …
