SU822812A1 - Method of determining functional state of myocardium of heart left ventricle - Google Patents

Description

-

The invention relates to mecicine, namely, to methods for diagnosing heart-systolic ababivations.

The known method of the functional condition of the myocardium of the left uaochka of the heart is measured by measuring the volume of the heart by the rapidity of the phases of the fast and. meopevogo exile.

The disadvantage of this method. Low accuracy.

The circuit of the invention is the provision of the ability to increase the accuracy of the method.

The above circuit is comprehended by the fact that, when implementing a method for maintaining the functional status of a client and a server by measuring the volume of the severity in terms of the phases of the fast ejection phase, a measure is made of the phases of the phases of the active exile, and the phases of the phase of the active ejection phase are measured by the efficiency of the phases of the fast exile, and the phases of the phase of the fast exile are quickly measured. the volume of blood that is expelled from the needle socket in the phase of rapid expulsion, according to the formula

Then, the blood volume / left from the left ventricle of the eperphage phase of the Medoil exile, the pa / systhophic blunton volume, taken over 100, and the volume of the blood expelled by the heart into the fast expulsion phase Qr iOO-Q, are determined. GUE Q - the volume of blood ejected from the first ventricle of the heart in the phase of foamy exile, expressed as a percentage of the systtopic volume. The functional state of the myocardium of the left ventricle of the heart is degraded by the ratio of the calculated blood volumes. The method is carried out by a specialist. Measurements of the phases of asynchronous paint AC, isometric contraction 1 and 1C, and fast ejection are measured. and meapenic exile Ef, for example, by the kinetoscartiographic method, and then calculated by the ratio between the epitheses of the measured phases of the cardiac cycle O 00 kiijiil D -Q HQO-Q, t ,. .27r / -i | V -H4. Acre) Q is the volume of blood emitted by the heart pouch into the rapid expulsion phase, expressed in pro cesses from the systtopic volume of the heart; the volume of blood thrown out by the geo-point of the heart in the phase of the expulsion leg of the expulsion, expressed in cents from the systhetic volume of the heart. Example. Bring to the test of the definition of disentangling the syspical volume of the heart on the volume of blood, selected as the left cardiac cord in 1EY of fast and slow exile) healthy, get both popes in age 17 and 43 peters, as well as in 18 bocn 24, (artonic bopecia). ssov, in 12 people, study proving, re-exercising in vice squats, sufficient CPU, increase the heart rate more than 80 beats per minute. Record the phase structure of the cardiac cycp in the exercise carried out by the method of high-frequency electro-magnetic display of a sert, which represents a kind of translucency of the thoracic fetus in the heart of the microwave with the emitter-magnetic papamus of the power. Slow nagnaggi E-fv and r {roezvodsh1s the calculation of phase volumes according to the given ratios. Examination has shown that in the group of healthy systhetic blood volume there is a decrease in phase volumes in such a process servings Q bt%, (2 33% in the group of healthy occupational load Ql e5% Q2--35% in the group bopk. Hypertoxic biopsy changes in the 3S preceiver .- 66%, and Q - within 34 ..- 42. The method provides an increase in the accuracy of the functional response of the lycovascular system of the perioral heart, which allows for more extensive information about the state of the cardiovascular disease. patient systems. The method of determining the functional state of the myocardium of the cardiac puddle by measuring the volume of the heart according to the duration of the phases of rapid and medial ejection, characterized in that, in order to improve the accuracy of the method, the duration of the phases of the asynchronous and isometric contraction of the same wedge are further measured The volume of blood ejected from the left heart of the heart into the phase of rapid ejection is given by the form Q | OO.p (AC, lC ,. where Q is the volume of blood ejected from the core heart into the phase n, expressed as a percentage of the systopic volume P, is a function displaying the Q / value (from the diameters of the heart of the heart of the cyclic Ac - the phase of the asynchronous contraction 1C - the phase of the isometric contraction of the E (-), the fast isometric phase of the E; Then, the volume of blood expelled from the heart pusher into the heart, the slow expulsion phase, is determined from the difference between the systolic volume of the heart. received by ICfO, and the volume of blood expelled by the heart into the phase of the rapid ejection of Gl, YOO-6i "o - the volume of blood ejected from the left ventricle of the heart into the phase of the slow exile, expressed as a percentage of the systtopic volume. The functional state of the myocardium of the ventricular ventricle of the heart is determined by the ratio of the calculated blood volumes.
