Aims and background: Management of unstable and refractory electrical storm (ES) requires a multidisciplinary approach in an intensive care unit (ICU). A dysregulated autonomic system is understood to be the cause of perpetual arrhythmogenesis. Case description: We present a case of refractory ES precipitated by myocardial ischemia (MI), which was promptly managed with primary percutaneous coronary intervention (PPCI). Despite successful reperfusion with PPCI, the patient continued to have arrhythmias for a prolonged period than expected. Due to refractory arrhythmia, escalation of antiarrhythmic drugs (AADs) along with sequential sympatholytic therapy was undertaken. Conclusion: The use of neuraxial modulation [initially stellate ganglion block (SGB) followed by surgical sympathectomy] may lead to the control of arrhythmia and hemodynamic stability in this difficult subset of patients. Clinical significance: Unstable ES is due to inappropriate sympathetic system activation and there is mounting evidence in support of neuraxial modulation as the main modality rather than escalating traditional AADs.
