PEREZ DIAZ, Pedro et al. Polymorphic ventricular tachycardia and non-compacted myocardium: A new genetic variant?. Rev. Colomb. Cardiol. [online]. 2020, vol.27, n.6, pp.597-601.  Epub Aug 03, 2021. ISSN 0120-5633.  https://doi.org/10.1016/j.rccar.2019.09.008.

Catecholaminergic polymorphic ventricular tachycardia is disease characterised by ventricular arrhythmias triggered by stress or physical activity. There are some cases of catecholaminergic polymorphic ventricular tachycardia described that are associated with non-compacted left ventricle in relation to mutations of the RYR2 gene located in exon 3. A case is presented of a young patient in whom the clinical signs started with recurrent syncope associated with physical or emotional stress. In the subsequent study, catecholaminergic polymorphic ventricular tachycardia was discovered, with areas of non-compacted myocardium and new genetic variant possibly associated with the disease.
