METHOD OF DIAGNOSING STAGES OF HEART VENTRICLES FIBRILLATION Russian patent published in 2009 - IPC A61B5/46 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to cardiology. Electrocardiogram is registered. In 1s ECG segments spectral power of teta-rhythm(4-7 Hz), alfa rhythm(8-12 Hz), beta-rhythm (13-17 Hz) and gamma-rhythm (18-40 Hz) is determined. Stages of ventricle fibrillations are determined. Beta-fibrillation is characterised by prevailing of beta-rhythm with power 40-70%, teta-fibrillation - by prevailing of teta-rhythm with power 40-70%, dysrhythmia - at the first place teta-, alfa- or beta-rhythm with power less than 40% and at the second - any rhythm with power less or equal to 30%. If power of teta-, alfa- or beta-rhythm is higher than 70% or in electrocardiogram section at the first place with respect to power is gamma-rhythm, absence of ventricles fibrillation is diagnosed.

EFFECT: method allows to determine stages of ventricle fibrillation and increase sensibility and specificity of fibrillation diagnostics.
