Hipertrofia ventricular izquierda diagnosticada con ecocardiograma transtorácico y su relación con los cambios electrocardiográficos.

To evaluate left ventricular hypertrophy diagnosed with transthoracic echocardiography and its relationship with electrocardiographic changes. Methods: An analytical observational study was carried out in patients treated by the cardiology service at the General Hospital of Barranquilla MiRed IPS, from October 2020 to March 2021. Results: From a total of 111 patients, 63.1% (n = 70) were female, the mean age was 64.1 ± 11.8; 21.6% (n = 24) had hypercholesterolemia, 26.1% (n = 29) took 3-hour weekly walks, and 44.1% (n = 49) were obese. 90.1% (n = 100) received treatment, being losartan the most widely used with 52.3% (n = 58), 77.5% (n = 86) complied with the treatment, and 67.6 % (n = 75) showed normal creatinine values 0-1.0 mg / dL. A significant difference was established between the categories of the electrocardiographic patterns, 39.0% (n = 30) with left ventricular hypertrophy had poor R wave progression in V3 (p <0.000), and 67.6% (n = 67) of those who did not show ventricular hypertrophy left, had other electrocardiographic findings, (p <0.000). The patients with concentric hypertrophy pattern corresponded to 76.6% (n = 59), (p <0.000); in those with eccentric hypertrophy, 23,4% (n=18) had a positive Sokolow-Lyon index on electrocardiography. None of the electrocardiographic findings was sufficiently accurate in estimating left ventricular hypertrophy. Conclusion: Low sensitivity in the electrocardiographic indices for the diagnosis of left ventricular hypertrophy is reported in this study, with a great difference in its diagnostic power compared to echocardiogram.
