[Idiopathic ventricular tachycardia, an arrhythmia with good prognosis].

Three patients, one experiencing palpitations and two complaining of chest pain in stressful situations, appeared to have monomorphic wide complex tachycardia. After excluding channelopathy, structural abnormalities and ischaemia of the heart, this arrhythmia was classified as idiopathic. Symptoms disappeared in one patient after using metoprolol, a β-adrenoceptor blocker.
