[Ultrasonic Doppler-cardiography as a method of study of cardiodynamics during flight based on patent and information analysis].

: This paper reviews patent and information data on the methods of cardiac location using ultrasound dopplercardiography, as well as on the design and development of onboard equipment to be used for medical monitoring of aircraft and spacecraft crewmembers inflight. It is emphasized that dopplercardiography, being a very informative, noise-proof and relatively simple technique, holds high promise for operational medical monitoring.
