To determine the anatomic correlates of electrocardiographic left ventricular hypertrophy (LVH) we performed an M-mode echocardiogram (echo) in 92 children (29 normals, 27 with aortic stenosis and 36 with aortic insufficiency). The ECG was normal in 53 and met criteria for LVH in 39 (including 1 normal). From the echo we measured LV end-diastolic diameter (EDD), septal and posterior wall thickness (PWT) and calculated LV mass. All normal subjects had a normal echo.
Of the 39 children with LVH by ECG, 19 (50%) had increased EDD and PWT, 8(20%) had only increased EDD, 8(20%) had only increased PWT and 4(10%) had a normal echo. In 20(51%) LV mass was increased. In all patients (pts) with a product of EDD × PWT > 5.2cm2 the ECG showed LVH.
Of the 53 children with a normal ECG, 44(83%) had a normal echo, 6(11%) had only increased PWT, 3(6%) had only an increased EDD and none had increased EDD and PWT. LV mass was increased in 7(13%); 11(24%) of pts with an abnormal echo had a normal ECG.
We conclude: (1) LVH on ECG may be due to an enlarged LV cavity, increased PWT or both, (2) children with EDD × PWT > 5.2cm2 consistently have LVH on ECG and (3) Most children with aortic valve disease and LVH by ECG have abnormal echo measurements.
