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) in myocardial infarction of the age of 1-2 days, necrosis neutrophilic granulocytes (NG) and fibroblasts (Fb) 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=2, NG=38, Fb=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<2 or -3.9, Lf>2; if the age of myocardial infarction is 3-5 days, the diagnostic coefficient is -2.1, if AFb<1, or the diagnostic coefficient is 7.2, if the absolute value of Fb>1; the diagnostic value of 1.36 is shown by the absolute value of NG<38; the diagnostic value is -11, if the absolute value is NG>38. The total value (?DC) is calculated by moving between the visual fields within the examined area, and if ?DC>12.78, the patient's death is stated to have come from ventricular fibrillation; if ?DC<-12.78, the death is stated to be caused otherwise.EFFECT: information value and reliability of the examination accompanying forensic medical examination.1 tbl, 3 ex |
