Available in PDF, EPUB and Kindle. Book excerpt: The auscultation method is an important diagnostic indicator for hemodynamic anomalies. Heart sound classification and analysis play an important role in the auscultative diagnosis. The term phonocardiography refers to the tracing technique of heart sounds and the recording of cardiac acoustics vibration by means of a microphone-transducer. Therefore, understanding the nature and source of this signal is important to give us a tendency for developing a competent tool for further analysis and processing, in order to enhance and optimize cardiac clinical diagnostic approach. This book gives the reader an inclusive view of the main aspects in phonocardiography signal processing.

Download or read book Signal Processing of the Heartbeat Cardiac Sounds written by Sidi Mohammed El Amine Debbal and published by . This book was released on 2020-12-16 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heart activity has long been the subject of various studies, including the first test performed by cardiologists on their patients and auscultation of heartbeats through an ordinary stethoscope. Therefore, the treatment of heart sounds in terms of recordings is very important for the diagnosis of various heart pathologies. The recorded signal is known as a phonocardiogram (PCG). The PCG signal confirms, and most importantly, refines the data of auscultation and provides additional information on sound activities regarding the chronology of pathological signs in the heart revolution, by locating them in relation to normal heart sounds. Heart sounds are by definition non-stationary signals (whose spectral properties therefore vary as a function of time) and are located in the low frequency range, approximately between 10Hz and 300Hz. The analysis of heart sounds by auscultation, based only on human hearing, remains insufficient for a reliable diagnosis of heart disease and for a clinician to obtain all the qualitative and quantitative information on cardiac activity. This information such as the temporal localization of the sounds of the heart, the number of their internal components, their frequency content, the importance of the diastolic and systolic murmurs can be studied directly on the PCG signal by the use of methods of digital techniques of the treatment of signal. The standard Fourier transform (FFT) can be used for the analysis of the PCG signal but it can only give information on the frequency content of the noise of the heart signal studied. This method remains limited in the case of non-stationary signals, which is the case with the PCG signal. Above all, the FFT is unable to provide indications concerning the temporal evolution of the analyzed signal if the criterion of stationarity is violated. The phonocardiogram signal representing the temporal evolution of heart sounds is considered, like many other signals in biomedical science, to be a non-stationary signal. To effectively understand such signals, it is important to study their time-frequency characteristics. The STFT (Short-term Fourier transform) as a method of timefrequency analysis can be applied. This consists of sliding an analysis window along the studied signal, but the dimensions of this window must be set so as to guarantee the conditions of stationarity. Unfortunately, these constraints cannot allow a good resolution in time and in frequency simultaneously.

"In addition to compiling the various imaging modalities used for clinical diagnosis in cardiovascular disease, the book also summarizes the present and future applications of combined imaging modalities for better understanding the underlying pathophysiologic basis of cardiovascular diseases....This book is unique in the way it comprehensively reviews both the current and future applications of multiple imaging modalities."--Doody's Review Service Multimodal Cardiovascular Imaging: Principles and Clinical Applications offers a unique “matrix” approach to help you choose the most appropriate combination of imaging modalities for the management of patients with cardiovascular disease. The book discusses the various options available, how they work, the benefits and drawbacks of each, and what modalities will best work in conjunction with each other for a specific condition. Featuring contributions from more than 60 international authors and enriched by 225 half-tone modality images and 130 full-color illustrations, Multimodal Cardiovascular Imaging: Principles and Clinical Applications is divided into three sections: Section 1 contains chapters that focus on the use of ten specific clinically available diagnostic modalities and their broad application to clinical cardiology. Modalities discussed include: Echocardiography Phonocardiography Myocardial Perfusion SPECT and PET Coronary Angiography Cardiac CT Section 2 includes six chapters that present “visions of the future” for combining multiple diagnostic modalities. They form the foundation for understanding the pathophysiologic basis of clinical cardiovascular conditions using prototypes, simulations, models, and tutorials. Section 3 considers several cardiovascular conditions and how multimodal imaging can provide diagnostic and therapeutic decision support to optimize the clinical care for each of them. Some chapters in this section also include case reports of how clinicians/scientists are using multimodal imaging modalities to improve their clinical therapeutic decision support. Conditions include: Congenital Heart Disease Ischemic Heart Disease Acute Myocardial Infarction Aortic Disease Atrial Fibrillation
