Introduction:

Left ventricular hypertrophy is an independent risk factor for cardiovascular disease. There are various electrocardiographic criteria for diagnosis, with different sensitivities and specificities.

Objective:

To determine the diagnostic value of electrocardiographic criteria for left ventricular hypertrophy in comparison to transthoracic echocardiography in adults with arterial hypertension.

Material and method:

Observational, descriptive, retrospective cross-sectional design, diagnostic test type, which included adult patients with a diagnosis of arterial hypertension admitted to the Medical Clinic rooms of the Hospital de Clínicas, Paraguay, from August 2022 to August 2023. Demographic variables, electrocardiographic criteria (Sokolow-Lyon, Cornell, Lewis, Peguero Lo Presti), and echocardiographic criteria for left ventricular hypertrophy were determined.

Results:

Five hundred seventeen electrocardiograms and echocardiograms of hypertensive patients were evaluated. According to the Sokolow-Lyon criteria, the sensitivity was 16% and the specificity was 70% for the diagnosis of left ventricular hypertrophy; by Cornell criteria, the sensitivity was 43% and specificity 87%; by Lewis criteria, the sensitivity was 26% and specificity 76% and by Peguero Lo Presti criteria. the sensitivity was 63% and the specificity 87%.

Conclusion:

The electrocardiogram criterion of left ventricular hypertrophy with the greatest sensitivity was that of Peguero Lo Presti and those with the greatest specificity were those of Peguero Lo Presti and Cornell.
