Radiofrequency catheter ablation of ventricular tachycardia from right ventricle late after myocardial infarction

Abstract

In summary, this case illustrates how complex VT circuits may be. If the findings of this case are substantiated with additional cases, mapping and radiofrequency energy application from right ventricle would have to be considered in VT with left bundle branch blocks QRS morphology, whenever ablation from the left ventricule is ineffective.
