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.read more

Electrocardiographic diagnosis of chamber enlargement.
TL;DR: Echocardiography is superior to electrocardiography in the detection of mild hypertrophy, and is more useful in the serial follow-up of changes during progression or regression of chamber enlargement.

TL;DR: Examination of P wave morphologies found them to be poorly sensitive but very specific for LA enlargement, specific and predictive of the degree of LA enlargements measured by echocardiography.

TL;DR: Established ECG criteria for LA enlargement do not reliably reflect LA chamber enlargement and lack sufficient predictive value to be useful clinically, so P-wave abnormalities should be noted as nonspecific LA abnormalities, with the term "LA enlargement" no longer used.
