The pathogenetic mechanisms of arrhythmias, including high-grade ventricular arrhythmias (including non-sustained ventricular tachycardia), in patients with coronary heart disease may be different. Therefore, the characteristics of ventricular arrhythmias must be considered based on the totality of data, taking into account all the available features. The importance of a personalized approach to the management of a patient with coronary heart disease who had extensive myocardial infarction 18.5 years ago, followed by mammary coronary artery bypass grafting, aneurysmectomy and the development of heart failure with a low ejection fraction, in whom ventricular arrhythmias occurred against the background of a stable course of coronary disease , but after emotional stress, is reflected in this work. An extended examination, as well as a detailed study of the nature of ventricular arrhythmias, made it possible to determine the main provoking factor and select an individualized pathogenetic treatment with a good antiarrhythmic result that persists for several years of observation. Conducting mental tests and psychological questioning can be recommended for patients with coronary heart disease and chronic heart failure as an additional examination to assess the contribution of the psycho-emotional factor to arrhythmogenesis after excluding the ischemic and sympathetic nature of ventricular ectopia. It is incorrect to consider that all ventricular arrhythmias in patients with coronary heart disease are ischemic in nature, and in some clinical situations this statement is even erroneous
