Abstract

Nonsustained ventricular tachycardia occurs commonly in the setting of acute myocardial infarction. By 24-48 hours after the onset of acute myocardial infarction, the incidence of nonsustained ventricular tachycardia declines. When analyzed as a dichotomous variable (present or absent), the presence of nonsustained ventricular tachycardia in the first 48-72 hours of acute myocardial infarction has been shown to have no prognostic significance. However, recent data suggest that the presence of nonsustained ventricular tachycardia in the first several hours during an acute myocardial infarction has no important prognostic significance, but that nonsustained ventricular tachycardia that occurs beyond the first several hours is associated with increased mortality. The pathogenesis of the increased mortality is unknown. Treatment should focus on the use of β blockers; specific antiarrhythmic drug therapy is not recommended. Polymorphic ventricular tachycardia is an uncommon arrhythmia in the setting of acute myocardial infarction. Its presence is thought to be associated with recurrent ischemia. Treatment should focus on aggressive attempts to reduce ischemia and intravenous amiodarone administration, if necessary.
