A comparison of electrocardiographic manifestations of left atrial
enlargement (LAE) and left atrial size by echocardiography was made in 307
patients in sinus rhythm. Electrocardiographic criteria used were L:P wave
duration in lead II equal to or greater than 0.12 sec; Va: the ratio of the
duration of negative terminal P in V1 to the P-R segment equal to or
greater than 1.0; Vb: a negative P terminal force in V1 less than -0.03 mm
sec. The echocardiographic diagnosis of left atrial enlargement was based
on 1) transverse dimension greater than 4.0 cm; or 2) a ratio of transverse
atrial to transverse aortic root dimension greater than 1.17. In the
presence of left atrial enlargement, a combination of criteria occurred
more often than a single criterion. The overall predictive index of the
electrocardiogram for left atrial enlargement was 63% (excluding criterion
Vb raised probability to 80%); and that for absence of left atrial
enlargement was 78%. The index of coarse versus fine fibrillary waves was
unreliable in predicting left atrial enlargement. Changes in P wave
morphology may be used as a reasonably specific but less sensitive
indicator of left atrial enlargement.
