RODRIGUEZ LOPEZ, Luis A. et al. Fragmented QRS and sudden death in a patient with arrhythmogenic right ventricular dysplasia/cardiomyopathy. CorSalud [online]. 2019, vol.11, n.1, pp. 70-74. ISSN 2078-7170.

The arrhythmogenic right ventricular dysplasia or cardiomyopathy is a genetic heart disease whose diagnosis is often a challenge for the clinician. It is one of the most common causes of sudden cardiac death in adolescence and in young adults. We present the case of a patient with a history of malignant ventricular arrhythmias and recovered sudden cardiac death due to arrhythmogenic right ventricular dysplasia, with QRS fragmentation in the right precordial leads, as a marker of the presence of a suitable substrate for the emergence of spontaneous ventricular fibrillation. The pathogenesis, diagnosis and treatment of this disease are discussed.

Keywords : QRS fragmentation; Sudden death; Arrhythmogenic right ventricular dysplasia.
