FIELD: medicine.
SUBSTANCE: auricular extrasystole recorded in the patient is analysed by calculating a relative coupling interval (RCI). The value is calculated by dividing a cardiac contraction interval immediately preceding the auricular extrasystole by the coupling interval. The derived RCI is assessed. If the value exceeds the value of 1.7, a high risk of developing paroxysmal atrial fibrillation is diagnosed in the patient.
EFFECT: method enables predicting a high probability of developing paroxysmal atrial fibrillation within the next hour.
