BACKGROUND: @entity4346 ( @entity4346 ) on the electrocardiogram (ECG) may be masked in the presence of complete @entity714 ( @entity714 ). @entity714 on the ECG is associated with @entity4346 at autopsy in 93% of hearts studied. However, @entity714 does not predict @entity4346 and the usual ECG criteria applied for @entity4346 may not be reliable in the presence of @entity714 . HYPOTHESIS: The study was undertaken to evaluate left @entity955 as a criterion for the diagnosis of @entity4346 in the presence of @entity714 . METHODS: @entity4032 in the ECG was assessed by two independent observers as a criterion of @entity4346 in the presence of @entity714 in 100 @entity1 , and data were compared with those of 50 @entity1 without @entity4032 . RESULTS: @entity4346 was confirmed by echocardiographic determination of left ventricular (LV) mass in both groups. Observers reliably differentiated between hypertrophied and normal-sized LV in the presence of @entity714 by using @entity4032 as an ECG criterion when correlated with LV mass determined by echocardiography. Observer 1 correctly detected @entity4346 in 88% and Observer 2 in 82% of @entity1 . False positive diagnosis was made in 12 and 18% of @entity1 by Observers 1 and 2, respectively. Observers' performance of recognition of @entity4032 in the present study was 94%. Results showed sensitivity of 76 and 70% and specificity of 84 and 92% for Observers 1 and 2, respectively. Left ventricular mass increased significantly and was diagnostic of @entity4346 in 92% of @entity1 with @entity4032 . Left ventricular mass was high in 84% of @entity1 when corrected by body surface area. @entity4346 in the presence of @entity714 by the ECG was found in only seven @entity1 (5%) when six commonly used conventional criteria of diagnosis of @entity4346 by ECG were employed. Regression analysis found @entity4032 to be a strong independent predictor of increased LV mass. Multiple regression analysis revealed that age, body mass index, body surface area, and frontal @entity2270 are also significant predictors of LV mass. CONCLUSION: The results obtained by the correlation of @entity4032 by ECG and @entity4346 by echocardiography conclude that @entity4032 by ECG was significantly diagnostic of @entity4346 in the presence of @entity714 .

@entity4032 by electrocardiogram predicts left ventricular hypertrophy by echocardiography in the presence of XXXX .
