Resumen

Las miocardiopatías constituyen un grupo importante y heterogéneo de enfermedades del miocardio asociadas a disfunción mecánica, eléctrica, o ambas. El ventrículo izquierdo no compacto es una miocardiopatía familiar de etiología incierta de la que se desconocen sus exactas incidencia y prevalencia. Se caracteriza por un aumento en la masa trabecular del VI en contraste con una fina capa epicárdica compacta que puede visualizarse con técnicas de imagen que confirman el diagnóstico. En este artículo se describen la clasificación de MOGE(S) para las miocardiopatías, los trastornos electrocardiográficos que pueden encontrarse en pacientes con ventrículo izquierdo no compacto, el papel de la estimulación eléctrica programada del corazón y otros aspectos de interés de esta enfermedad. Además, se presentan algunos trastornos electrocardiográficos demostrativos (criterios de Stollberger y Jenni) encontrados en pacientes afectados.
