ABSTRACT
Myocardial infarctions due to left circumflex artery (LCX) occlusions are under-diagnosed and mismanaged. We describe a case of an occult total occlusion of the LCX artery that presented with atypical symptoms, which then degenerated into convulsive syncope, polymorphic ventricular tachycardia and cardiac arrest, before being taken for emergent coronary angiography.
