RESUMEN
Echocardiography is an important adjunct to clinical diagnosis. Evaluation of chamber size, estimation of left ventricular function, valvular defects, and tricuspid atresia or stenosis are among the many disorders in which it can be helpful.

Electrocardiographic criteria for left atrial enlargement (LAE) were evaluated in a group of 100 patients with a wide spectrum of cardiovascular diseases and compared with the echocardiographic measurement of left atrial dimension (LAD). Data analysis showed a high degree of correlation between the echocardiographic measurement of LAD and the EKG criteria for LAE. The magnitude of the P terminal force in lead V1 was the most specific of the EKG criteria evaluated, while the P/P-R segment ratio was least specific. Concordance between the two methods of measuring left atrial size increased when multiple positive EKG criteria were present.
