Innovative methods of ventricular arrhythmia treatment

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.
