The most common antiarrhythmic medications used for suppression of VA include amiodarone and sotalol, while mexiletine, quinidine, and ranolazine are occasionally used.S7.1.3-17,S7.1.3-18 Amiodarone appears to be more effective than sotalol and has a low rate of ventricular proarrhythmia, but has an increased risk of medication-related adverse effects that lead to its discontinuation in many patients within 18 to 24 months from initiation of therapy.S7.1.3- Data supporting effectiveness of sotalol for suppression of VA are conflicting, but given its more favorable adverse effect profile than amiodarone, it may be a better first-line antiar- rhythmic medication in appropriate patients.S7.1.3- However, sotalol is generally avoided in patients with a severely reduced LVEF <20% due to its negative inotropic effects and the risk of torsades de pointes. In a double-blind placebo- controlled study of 674 patients with HF and 10 PVCs/h and an LVEF 40% randomly assigned to receive amiodarone (336 patients) or placebo (338 patients), there was no significant difference in overall mortality or SCD between the 2 arms. There was a trend toward a reduction in overall Figure 5. Treatment of recurrent VA in patients with ischemic heart disease or NICM. Colors correspond to Class of Recommendation in Table 1. See Sections 5.6, 6, 7.1.3, and 7.2 for discussion. *Management should start with ensuring that the ICD is programmed appropriately and that potential precipitating causes, including heart failure exacerbation, are addressed.
