title: [Hypertrophic cardiomyopathy. Arrhythmia in hypertrophic cardiomyopathy].
abstract: Hypertrophic cardiomyopathy is a relatively common genetic disorder with heterogeneity in mutations, forms of presentation, prognosis and treatment strategies. Hypertrophic cardiomyopathy is recognized as the most common cause of sudden cardiac death that occurs in young people, including athletes. The clinical diagnosis is complemented with the ecocardiographic study, in which an abnormal myocardial hypertrophy of the septum can be observed in the absence of a cardiac or systemic disease (arterial systemic hypertension, aortic stenosis). The annual sudden mortality rate is 1% and, in selected populations, it ranges between 3 and 6%. The therapeutic strategies depend on the different subsets of patients according to the morbidity and mortality, sudden cardiac death, obstructive symptoms, heart failure or atrial fibrillation and stroke. High risk patients for sudden death may effectively be treated with the automatic implantable cardioverter-defibrillator.
