Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to cardiology, and can be used for prediction of ventricular tachyarrhythmia (VTA). Patient is examined for the following: a diagnosis of atrial fibrillation (AF) at the moment of implantation (X1); presence of atrial flutter in past history and at implantation of device (X2); presence of persistent atrial fibrillation at programming visit of implanted device (X3); reported paroxysmal AF by implanted device data or directly at patient's visit (X4), value of heart rate (X5, beat/min) at visit of patient. Further, the logistic function is calculated to estimate the true VTA detection risk by the claimed formula. From obtained values of logistic function ψ risk of true VTA is evaluated. If the value ψ less than -2.94, risk of true VTA detection is less than 5 %. If the value ψ from -2.94 to 0, risk of true GTA detection from 5 to 50 %. If the value ψ 0–2.94, risk of true VTA detection is 50–95 %. If the value ψ more than 2.94, risk of true VTA detection more than 95 %. 
     EFFECT: method enables to predict the probability of detecting true VTA in patients with implanted devices, reducing the risk of applying unmotivated electrotherapy in the implanted electronic device (ICD) as a result of supraventricular tachyarrhythmias by evaluating the complex of the most significant indicators.
