[The use of an echocardiograph and a rheoplethysmograph for computing the volume of the reverse blood flow in the atrioventricular heart valves].
The method of the combined use of the 2 series-produced outfits, an echocardiograph and an rheoplethysmograph, has been devised and tried on a clinical basis. The design parameters of the outfit make it possible to display the chest differential rheogram (DRG) obtained on an outfit on the screen of a cathode-ray tube. It is only one-stage recording of the echocardiogram of the right or (and) left ventricle and of the chest DRG that permits computing the volume of the reverse blood flow (regurgitation) in the atrioventricular valves of the heart. During separate use of these outfits, it is not feasible to measure the volume of regurgitation in the atrioventricular valves. The method suggested can be used for the design of an outfit with a broader range for studying heart anatomy and function.
