ELEKTROKIMOGRAFIYA

From Big Medical Encyclopedia

ELEKTROKIMOGRAFIYA [an electron (from «electricity») + a Greek jackpot a wave + grapho to write, represent; a synonym a rentgenoelektrokimografiya] — the radiological method of assessment of motive activity of internals based on registration of fluctuations of optical density of the image (shift of a contour of moving body) on the x-ray screen.

As E. it is accompanied by quite high level of radiation of the patient, now resort to it seldom and give preference to such methods as an echocardiography (see), video densitometry (see t. 10, additional materials).

AA. it was developed and is for the first time used in clinic in 1947 Mr. of Henny (G. Page of Henny), Boone (V. R. Boone) and Chamberlain (E. W. Chamberlain).

AA. it is carried out by means of the photosensor, to-ry establish respectively to a certain point of the fluoroscopic image. Elektrokimogramma — record of change of brightness of the screen owing to shift in a zone of the photosensor of a contour of moving body (e.g., hearts, aortas, diaphragms).

AA. it is possible to make in usual X-ray department with use of domestic elektrokimograf EKS-60.

AA. heart and vessels allows to study sokratitelny ability and a tone of a myocardium, disturbance of a hemodynamics in cameras of heart, a pulsation of an aorta, a pulmonary trunk, an upper vena cava. AA. it is effective in diagnosis of the squeezing pericardis and hron. aneurisms of heart. Simultaneous record of an elektrokimogramma and ECG allows to carry out the phase analysis of the movement of contours of heart. AA. lungs gives the chance to estimate their ventilation and blood circulation throughout all respiratory cycle and in different uchast ka of body. By means of E. perhaps also studying of depth, symmetry and synchronism of the movement of the right and left parts of a dome of a diaphragm.
