  • Title: Transition of the ST segment from a J wave to a coved-type elevation before ventricular fibrillation induced by coronary vasospasm in the precordial leads.
    Author: Inoue M, Matsubara T, Yasuda T, Miwa K, Kanaya H.
    Journal: J Electrocardiol; 2010; 43(5):418-21. PubMed ID: 20667548.
    Abstract:
    We describe the case of a 63-year-old man whose electrocardiogram showed transition of the ST segment from a J wave to a coved-type elevation in precordial leads before ventricular fibrillation induced by right coronary artery vasospasm. Simultaneously, the ST segment in inferior leads was gradually depressed with a J wave. Considering the sudden death of his son, induced ventricular fibrillation by programmed electrical stimulation, and modulations of the ST segment in the precordial and inferior leads by pilsicainide, some abnormalities in repolarization associated with Brugada syndrome or early repolarization syndrome might have caused these atypical ST-segment manifestations.
