The authors summarized the experience of the use of the stimulus and the activation mapping under fluoroscopic control to search for sources of ventricular ectopic followed by radio-frequency effects on the vulnerable zone arrhythmias. The authors presented an algorithm for finding a pathological focus on the basis of an evaluation of the surface electrocardiogram, followed by sequential endocardial mapping. The results of radiofrequency ablation of ventricular arrhythmia in different localization of the source are presented. The authors generalized and systematized the experience detection and cure of ventricular ectopy in 65 patients. The regularities of changes in the ventricular complex according to surface electrocardiogram in certain localizations of ectopic focus are revealed. Effectiveness of the operation of radiofrequency ablation with ventricular arrhythmias was about 90%, which is generally consistent with data from other clinics. Complications requiring additional interventions were not. Highlight the work areas of the endocardium, analysed the causes of inefficient operations and poor results. Alternative methods of destruction of the endocardium in complex localization of ectopic focus are suggested.

Background: Atrial fibrillation (AF) is the most prevalent arrhythmia encountered in clinical practice. Triglyceride glucose index (Tyg), a convenient evaluation variable for insulin resistance, has shown associations with adverse cardiovascular outcomes. However, studies on the Tyg index's predictive value for adverse prognosis in patients with AF without diabetes are lacking.

The electrophysiological mechanisms underlying melatonin's actions and the electrophysiological consequences of superimposed therapeutic hypothermia (TH) in preventing cardiac ischemia-reperfusion (IR) injury-induced arrhythmias remain largely unknown. This study aimed to unveil these issues using acute IR-injured hearts. Rabbits were divided into heart failure (HF), HF+melatonin, control, and control+melatonin groups.

Background: Myocardial disease is an important component of the wide field of cardiovascular disease. However, the phenomenon of multiple myocardial diseases in a single patient remains understudied.
Aim: To investigate the prevalence and impact of myocarditis in patients with genetic cardiomyopathies and to evaluate the outcomes of myocarditis treatment in the context of cardiomyopathies.
