Bilateral thoracic sympathetic block for refractory polymorphic tachycardia

摘要

Introduction Extensive evidence has established a link between sympathetic nervous system hyperactivity, ventricular arrhythmias, and sudden cardiac death. For this reason, cardiac sympathectomy is often beneficial in the treatment of patients at high risk for ventricular ectopy, although it involves an invasive procedure associated with potential morbidity. We report a case in which we used guided lytic thoracic sympathetic block in a patient with underlying cardiomyopathy and refractory polymorphic ventricular tachycardia.
