METHOD OF RENDERING EMERGENCY CARDIAC CARE

FIELD: medicine.SUBSTANCE: invention relates to medicine, namely, to a method for selecting a method for providing emergency cardiac care. Method includes the determination of: electrocardio-signal (ECS): Standard Deviation of the Averages of NN (SDANN), ratio of low and high frequency waves (LF / HF), variability of the QT (varQT) interval and the ejection fraction (EF) during the day, with calculating the coefficient K of the prediction of the severity of the arrhythmic syndrome according to the formula: K = -4.518 + 0.02FV + 0.037SDANN + 0.049LF / HF-0.019varQT. Presence or absence of extension of the QT interval is preliminary determined by the expression:(1), where RR- the distance between adjacent teeth R on the EKS, c; k is a coefficient of 0.37 for men, 0.39 for women, and 0.38 for children. Value of EF is determined, at least, for the next three cardiocycles by expression:(2), where EDV, ESV - end-diastolic and systolic volume of the left ventricle, respectively, defined by the formulas:, where EDV, ESV - end-diastolic and systolic volume of the left ventricle, respectively, End diastolic dimension (EDD) is determined by the formula: EDV = (44.5-100⋅t)⋅(t+ t)-eleven⋅t, where t- the time from the beginning of the Q wave to the apex of the R wave in the absence of blocking the left leg of the bundle, and if there is a blockage of the left branch of the bundle, the Gis to the first vertex of the bifurcated tooth R (R1) so t= t, c; t- the time from the apex of the tooth R to the end of the tooth S - in the absence of bundle block blocks of the bundle, and when the left bundle block is blocked, instead of t- the difference of the time intervals from the first vertex of the bifurcated tooth R to the end of the tooth S (R1 S) and from the first vertex of the bifurcated tooth R to its second vertex (RR), that is; end systolic dimension (ESD) is determined by the formula:where t- the time of the QRS complex, c; t- the time from the end of the tooth S to the end of the T wave - in the absence of bundle blocks of the bundle of the bundle, and with the blockade of the left leg of the bundle,use the amount, when the right bundle of the Heis bundle is blocked, instead of t- amount. With all these types of heart rhythm, ventricular tachycardia and extrasystole are determined for at least the next three cardiocycles. In case where expression (1) is true, in three or more subsequent cardiac cycles there is ventricular tachycardia and extrasystole, and EF
