Abstract
Ventricular arrhythmias are usually well controlled with medical management, cardiac implantable electronic devices, or catheter ablation. However, the refractory ventricular tachycardia or fibrillation (VT/VF) is life threatening and challenging. The authors reported a case series of left stellate ganglion blocks (LSGB) in patients with refractory VT/VF, who failed pharmacological treatment and multiple traditional cardiac interventions. Five patients underwent six LSGB. Four patients had significant decreased in ventricular arrhythmia burden. Among the responders, the LSGB suppressed significant VT/VF for three to seven days. Blocks did not only temporary suppress ventricular arrhythmia, but also stabilized the condition and served as a bridge to definitive treatment such as EP ablation or heart transplantation. There was no significant hemodynamic change or devastating side effects. The outcome from the present case series suggested that LSGB could be an effective treatment and a lifesaving intervention for intractable VT/VF.
