Case Report Bidirectional Ventricular Tachycardia Secondary to Subacute Myocarditis

We report a case of subacute myocarditis with severe heart failure referred for urgent cardiac transplantation. The patient had an episode of bidirectional ventricular tachycardia during the acute admission. Subacute myocarditis should be added to the limited differential diagnosis of bidirectional ventricular tachycardia. RESUME Nous rapportons le cas d’un patient ayant une myocardite subaigue associee a une insuffisance cardiaque severe qui a ete dirige vers la transplantation cardiaque urgente. Le patient a eu un episode de tachycardie ventriculaire bidirectionnelle lors de l’admission en soins de courte duree. La myocardite subaigue devrait etre ajoutee au diagnostic differentiel limite de tachycardie ventriculaire bidirectionnelle. Bidirectional ventricular tachycardia (VT) is a rare rhythm disorder that is usually described in digoxin toxicity and familial catecholaminergic polymorphic VT. Rarer causes include acute myocardial infarction, familial hypokalemic periodic paralysis, aconitine poisoning, fulminant myocarditis, mutations intheKCNJ2gene,noncompactioncardiomyopathy,andpul
