VILLAMIL-MUNEVAR, Alejandro; ALVARADO, José  e  OLAYA-SANCHEZ, Alejandro. J-Wave, predictor of sudden death. Rev. Colomb. Cardiol. [online]. 2016, vol.23, n.3, pp.168-171. ISSN 0120-5633.  https://doi.org/10.1016/j.rccar.2015.07.007.

It used to be believed that the syndrome of early repolarization, which is determined by the point J and ST segment on the electrocardiogram, was a benign pattern. In recent decades its malign character has been shown when presented in the inferior leads and/or side given its potential to trigger lethal arrhythmias (occurs 1-13% of the general population and in 15-70% of cases of idiopathic ventricular fibrillation), as in the case of idiopathic polymorphic ventricular tachycardia that can degenerate into ventricular fibrillation and sudden death. A case of a 41 year-old patient who initially presented episodes of palpitations, syncope and sudden death is presented, in whom subsequently early repolarization type 2 disorder is evidenced.
