Bioelectrical signal processing in cardiac and neurological applications pdf
Bioelectrical signal processing in cardiac and neurological applications - Semantic ScholarA biosignal is any signal in living beings that can be continually measured and monitored. The term biosignal is often used to refer to bioelectrical signals, but it may refer to both electrical and non-electrical signals. The usual understanding is to refer only to time-varying signals, although spatial parameter variations e. Electrical biosignals, or bioelectrical time signals, usually refers to the change in electric current produced by the sum of an electrical potential difference across a specialized tissue, organ or cell system like the nervous system. Thus, among the best-known bioelectrical signals are:.
Bioelectrical Signal Processing in Cardiac and Neurological Applications
The analysis of bioelectrical signals continues to receive wide attention in research as well as commercially because novel signal processing techniques have helped to uncover valuable information for improved diagnosis and therapy. This book takes a unique problem-driven approach to biomedical signal processing by considering a wide range of problems in cardiac and neurological applications—the two "heavyweight" areas of biomedical signal processing. The interdisciplinary nature of the topic is reflected in how the text interweaves physiological issues with related methodological considerations. Bioelectrical Signal Processing is suitable for a final year undergraduate or graduate course as well as for use as an authoritative reference for practicing engineers, physicians, and researchers. A problem-driven, interdisciplinary presentation of biomedical signal processing Focus on methods for processing of bioelectrical signals ECG, EEG, evoked potentials, EMG Covers both classical and recent signal processing techniques Emphasis on model-based statistical signal processing Comprehensive exercises and illustrations Extensive bibliography. This action might not be possible to undo.
The present article reviews two recent books dealing with rather closely related subjects; in fact, they tend to complement and supplement reciprocally. Obviously, the electromyogram is a bioelectrical signal that often is mathematically manipulated in different ways to better extract its information. Moreover, its correlation with other bioelectric variables may become necessary. Civil Engineering appeared, say, during the Industrial Revolution XVIIIth-XIXth Centuries , even though there are countless previous contributions in hydraulics, mechanics and other areas [ 1 ], making use of ingenuity in civilian applications at large, as some kind of counter-face of Military Engineering. Specializations within the former showed up slowly first Naval, Mechanical, Electrical to speed up its diversification in the XXth Century with Telecommunications, Electronics, Computers and several other branches and sub-branches. Their signals must be read and interpreted, beyond the limited abilities of the naked eye and the associated human experience [ 2 ]. Here is where the field of Biomedical Signal Processing BSP takes personality in its own right as interdisciplinary indispensable tool, full of ingenious new ideas and concepts.
The analysis of bioelectrical signals continues to receive wide attention in research as well as commercially because novel signal processing techniques have helped to uncover valuable information for improved diagnosis and therapy. - Atrial Fibrillation from an Engineering Perspective provides an up-to-date overview of techniques developed for acquisition, modeling, and analysis of noninvasive, bioelectrical signals reflecting this common arrhythmia.
