METHOD FOR DETERMINING RISK OF ATRIAL FIBRILLATION IN PATIENTS WITH PREMATURE ATRIAL CONTRACTION Russian patent published in 2015 - IPC A61B5/02 

FIELD: medicine.

SUBSTANCE: patient with premature atrial contraction (PAC) undergoes ECG study. A signal-averaged ECG is recorded. The method involves measuring the length of a filtered push-pull (FiP-P) wave of the signal-averaged ECG (ms), P wave dispersion determined as a difference of maximum and minimum P wave lengths while recording 12 leads of the standard ECG (Pd) (ms), a linear deviation (A), B that is the number of premature atrial contractions per hour, a risk index of developing atrial fibrillations (RIDAF) by an original formula. If the RIDAF is less than 0.5, the high risk of atrial fibrillation is predicted for 1-3 months; the RIDAF from 0.5 to 1.5 stands for the moderate risk during 3 months to 1 year, whereas the RIDAF of more than 1.5 shows the low risk for more than 1 year from the first examination of the patient suffering from premature atrial contraction.

EFFECT: method enables increasing the determination accuracy of the risk of atrial fibrillation following the first examination and correcting the therapy.
