Abstract
Objective: To present data on left ventricular hypertrophy (LVH), addressing its risk factors, its signs, symptoms, differentiation between pathological and physiological LVH and the main tests used in its diagnosis, focusing on the electrocardiogram. Bibliographic review: The LVH is a condition that, depending on its etiology, has the possibility of being serious. It may not manifest symptoms at first, but during its progression to the chronic phase it brings many cardiovascular complications. Aiming at the pathological factor, the individual will start an exuberant clinical decline that compromises health and quality of life, and may lead to death according to all the articles studied. Final considerations: LVH is a chronic and severe condition, which may be associated with several etiologies, including congenital. On the other hand, there is a need for early diagnosis and preventive measures to avoid the complications of this serious health problem. Although recent studies have been carried out in this area, the electrocardiogram remains a fundamental instrument in the cardiologist's daily practice. Its diagnostic sensitivity, however, is still relatively limited, despite its usefulness in identifying LVH.
