Stellate Ganglion Block for Electrical Storm Associated With Takotsubo Cardiomyopathy: A Case Report.

Takotsubo cardiomyopathy (TCM) is a reversible condition characterized by apical ballooning of the left ventricle, primarily triggered by catecholamine discharge due to stress. Patients may present with symptoms similar to acute coronary syndrome or with refractory ventricular arrhythmias such as QT prolongation, ventricular tachycardia, and ventricular fibrillation. We report a case of TCM with prolonged QT intervals and refractory ventricular arrhythmias, triggered by noncardiac systemic insult, that responded successfully to stellate ganglion block (SGB). This case highlights the potential of SGB as an effective intervention for managing refractory arrhythmias in TCM patients.
