Abstract:The use of an intracardiac sound source to determine transfer functions and propagation paths and modes for the thorax using digitial data reduction techniques is discussed. It is important to know the sound transmission characteristics of the thorax for diagnostic purposes. Studies made using naturally occurring heart sounds have not satisfactorily defined either the origin or the transmission modes and paths for the signals. An intracardiac sound source inserted by standard cardiovascular catherization techn… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
