[Polymorphous ventricular tachycardia in acute myocarditis ]

Myocarditis may present with a variety of electrocardiographic patterns. However, polymorphous ventricular tachycardia (PVT), potentially a highly malignant ventricular arrhythmia, has not been described in acute myocarditis. As far as we know, this is the first report of this arrhythmia in that condition. It is characterized by unusual resistance to both the common pharmacological and nonpharmacological approaches. This report of a 28-year-old woman demonstrates the role of PVT as a potential cause for sudden death among patients with subclinical myocarditis.
