ABSTRACT

Introduction: Left ventricular hypertrophy is a major problem among patients with high blood pressure worldwide; it is also related to various entities, which can be fatal.
Objective: To evaluate the diagnostic performance of the Sokolow-Lyon index in precordial leads for left ventricular hypertrophy.
Method: An observational, analytical and cross-sectional study of diagnostic means was carried out. One hundred and twenty-two patients admitted to the Departments of Internal Medicine, Nephrology and Neurology of the Hospital Militar Carlos J. Finlay (Havana, Cuba) were studied from January 2017 to March 2019, who underwent echocardiography and electrocardiogram.
Results: There was a predominance of the population over 45 years old (77.9%), males (59.8%) and with high blood pressure (77.0%). A qualitative description of the Sokolow-Lyon electrocardiographic index for precordial leads was performed in the total number of the studied cases, and a prevalence of 71.3% of left ventricular hypertrophy was found. This voltage criterion showed high specificity (83%), high positive predictive values (85%) and positive likelihood ratio at 2.28.
Conclusions: In admitted patients, where the prevalence of high blood pressure is high elevated, the Sokolow-Lyon criterion presented high diagnostic usefulness for left ventricular hypertrophy as well as to confirm the cases that actually present it.
