Abstract:
The role of radiofrequency ablation in the acute management of electrical storm is reviewed. Electrical storm is defined as three or more intervention-requiring episodes of ventricular fibrillation or ventricular tachycardia within 24 hours. The management of electrical storm includes antiarrhythmic therapy including beta blockers and correction of initiating causes as myocardial ischaemia and electrolyte disturbances. Radiofrequency ablation provides an alternative in the management of electrical storm in the case of failure of the medical therapy.
