The use of angiocardiography in physiological experiments
- 13 Downloads
A simple device, suggested by I. S. Amosov and modified by the authors, made it possible to record 9 serial angiocardiograms, 10×40 cm in size, in 8 sec. This proved to be a sufficient number for serial angiocardiography (rabbits, cats) in the assessment of the circulation.
Soviet cardiotrast was used as a contrast medium. The study of these serial angiocardiograms enables the time of filling by the contrast medium of the cardiac cavities, pulmonary veins and arteries, as well as of aorta and large arteries to be determined. The width of the lumen of the great vessels and the individual heart chambers could also be studied. The time when the contrast substance enters and leaves the kidney, as well as the time of filling of the urinary bladder may also be assessed. Various changes occurring in the blood flow as the result of action of different pharmacological substances, in anaphylactic shock or injury of the extremity and distinctly seen on the serial angiocardiograms.
