Résumé
A 44-year-old woman with previous myocarditis underwent several syncopal events due to self-terminated ventricular fibrillation (VF) with hypokalemia. Electrocardiogram showed a normal QT duration and premature ventricular contraction with a short coupling interval (280 ms), and the R-on-T phenomenon induced Torsade de pointes (TdP) that deteriorated into VF, a condition known as short coupled TdP (ScTdP). Cardiac magnetic resonance imaging showed left ventricular dilatation and diffuse high T2 signal intensity, and endomyocardial biopsy exhibited a failing myocardium. This is a rare case of ScTdP accompanied by a failing myocardium. Some instances of ScTdP may be associated not only with an electrical disorder but also with a structural myocardial disorder. <
