Abstract:We observed instantaneous blood flow velocity profiles at the right and left ventricular outflow tracts, the ascending aorta, and the lower thoracic aorta in human subjects using a newly devised method of real-time multichannel Doppler echocardiography. In 20 apparently healthy subjects, the blood flow velocity profile was successfully obtained in all cases at the right and left ventricular outflow tracts--in 13 cases at the ascending aorta, in 12 cases at the aortic arch, and in ten cases at the lower thoraci… 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.
