METHOD FOR CONFIRMATION OF DEATH CAUSED BY VENTRICULAR FIBRILLATION ACCOMPANYING MYOCARDIAL INFARCTION Russian patent published in 2015 - IPC G01N33/483 

FIELD: medicine.

SUBSTANCE: for the purpose of the confirmation of a patient's death caused by ventricular fibrillation accompanying myocardial infarction in the patients died from myocardial infarction in the course of autopsy on the basis of a macroscopic pattern, the pathological process age is determined. This enables selecting examination areas in the heart at the level of necrosis. Absolute values (AV) of the following cell populations are counted in the x600-magnified visual field with using haematoxylin and eosin: necrosis-borderline lymphocytes (Lf_b) in myocardial infarction of the age of 1-2 days, necrosis neutrophilic granulocytes (NG_n) and fibroblasts (Fb_n) in myocardial infarction of the age of 3-5 days. The derived absolute values are compared to threshold values (TV) with the threshold values of Lf_b=2, NG_n=38, Fb_n=1. Each visual field is assigned with a diagnostic coefficient (DC), which is equal to 1.9 at the age of myocardial infarction of 1-2 days, if the absolute values Lf_b<2 or -3.9, Lf_b>2; if the age of myocardial infarction is 3-5 days, the diagnostic coefficient is -2.1, if AFb_n<1, or the diagnostic coefficient is 7.2, if the absolute value of Fb_n>1; the diagnostic value of 1.36 is shown by the absolute value of NG_n<38; the diagnostic value is -11, if the absolute value is NG_n>38. The total value (ΣDC) is calculated by moving between the visual fields within the examined area, and if ΣDC>12.78, the patient's death is stated to have come from ventricular fibrillation; if ΣDC<-12.78, the death is stated to be caused otherwise.

EFFECT: information value and reliability of the examination accompanying forensic medical examination.
