摘要
FIELD: medicine.;SUBSTANCE: invention relates to medicine, namely to cardiology. At the preoperative stage, topical diagnostics of the focus of arrhythmia is performed, wherefor recording electrodes are attached to the surface of the chest of the patient to conduct surface non-invasive electrophysiological cardiac mapping (NEPCM) and an exercise tolerance test (ETT) is performed, followed by transferring the patient to a horizontal position when the criteria for a positive ETT test are reached, while recording a multi-channel ECG from the surface of the torso of the patient, and continuing to record the multi-channel ECG for the duration of the recovery period. A CT or MRI of the chest of the patient is performed with attached electrodes, the results of the ECG, CT or MRI of the chest are processed. The location of the focus of arrhythmia recorded against the ETT test is determined and compared to the blood supply area of the coronary artery (CA) with hemodynamically significant stenosis, obtained based on the results of coronary angiography (CAG), and if the localisation of the focus of arrhythmogenesis matches the blood supply area of the CA with hemodynamically significant stenosis, antiarrhythmic (AA) effectiveness of the myocardial revascularisation (MR) operation is predicted. If the location of the focus of arrhythmogenesis does not match the blood supply area of the CA with hemodynamically significant stenosis, the absence of AA effectiveness of the operation is predicted.;EFFECT: provides a possibility of predicting the AA effectiveness of the MR operation at the preoperative stage, selecting the proper procedure for managing IHD patients with VAs associated with myocardial ischemia, and also identifying the CA, located in the blood supply area whereof is the focus of the VA, the blood flow wherein needs to be restored at the operative stage.;1 cl, 3 ex
