What is the recommended treatment for sustained VT or VF in patients with STEMI?
Treatment consists of immediate defibrillation or cardioversion for VF or pulseless sustained VT, respectively, and antiarrhythmic drug therapy in accordance with the 2010 Advanced Cardiac Life Support guidelines for sustained VT with a pulse. Early (within 24 hours of presentation) administration of beta blockers has been associated with a reduction in the incidence and is recommended for all patients without contraindications (Section 8.1). The prophylactic use of lidocaine is not recommended.
