DIAGNOSTIC METHOD OF VENTRICULAR FIBRILLATION Russian patent published in 2019 - IPC A61B6/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to cardiology. Disclosed is a method in which: recording an electrocardiogram (ECG) or an electrogram of the ventricles (EGV) of the heart. Spectral power of frequencies 0.5, 1, 1.5 …, 15 Hz is determined in segments of ECG (EGV) and frequency of 1-3-th spectral power of frequency range 0.5–15 Hz is determined. If the frequency value of 1-3th frequency exceeds 4 Hz, the difference between the highest and lowest values of these frequencies is determined; if difference is 1 Hz, the ventricular fibrillation is diagnosed. If frequency value 1, 2 or 3 frequency is not more than 4 Hz or the difference between the highest and lowest values of 1-3-th frequencies is more than 1 Hz, the diagnosis is the absence of ventricular fibrillation.

EFFECT: invention provides higher sensitivity and specificity of diagnosing fibrillation.
