Does propranolol eliminate electrical storm in a patient post-acute myocardial infarction?
Non-selective beta-blocker propranolol successfully terminated electrical storm in a patient post-acute myocardial infarction.
May support propranolol for refractory post-MI electrical storm; hypothesis-generating case report requiring prospective validation.
Background: Electrical storm is a life-threatening syndrome with dramatic clinical presentation. It presents with 3 or more episodes of sustained ventricular tachycardia or ventricular fibrillation during 24 hours with hemodynamic instability requiring termination with DC shocks. In general the prognosis of this syndrome is unfavorable. Case report: We present a patient with electrical storm 12 days after the acute myocardial infarction terminated with non-selective beta blocker Propranolol. The patient was stabilized with 80mg of Propranolol qd and the storm was eliminated. Conclusion: The efficient treatment of electrical storm implies understanding of arrhythmia mechanisms, and different treatment modalities (from implantable cardioverter defibrillator placement to radio frequent catheter ablation).

Selaković et al. (2017) conducted a case report in Electrical storm after acute myocardial infarction (n=1). Propranolol vs. Previous antiarrhythmic therapy (lidocaine, amiodarone, bisoprolol) was evaluated on Termination of electrical storm (ventricular tachycardia episodes). Administration of the non-selective beta-blocker propranolol at 80 mg/day successfully terminated a refractory electrical storm in a patient 12 days post-acute myocardial infarction.
