%X Electrocardiographic left ventricular hypertrophy (LVH) diagnosed by Cornell product and the Sokolow每Lyon voltage are associated with anatomical LVH; therefore, we investigated whether Cornell product and the Sokolow每Lyon voltage were associated with echocardiographic regional wall motion (measured by 2D-strain imaging). We reviewed data on 288 consecutive hypertensive patients who underwent both echocardiography and electrocardiography. Electrocardiographic LVH was calculated as follows: Cornell voltage, S in lead V3ˋ+ˋR in lead aVL; Cornell product, Cornell voltage (+0.6ˋmV for females)ˋ℅ˋQRS duration; and Sokolow每Lyon voltage, S in lead V1ˋ+ˋR in lead V5. The mean age of the subjects was 64.3ˋ㊣ˋ13.2 years; 47.9% were men, and 65.2% were taking antihypertensive medications. Both Cornell product (rˋ=ˋ0.392, Pˋ<ˋ0.001) and the Sokolow每Lyon voltage (rˋ=ˋ0.315, Pˋ<ˋ0.001) were significantly related to left ventricular mass index (LVMI), and the relationship between Cornell product and LVMI (betaˋ=ˋ0.24, Pˋ=ˋ0.001) was independent of the Sokolow每Lyon voltage (betaˋ=ˋ0.25, Pˋ<ˋ0.001). In multivariate linear regression analysis in which the two ECG-LVH were included together, Cornell product was related to global longitudinal strain (betaˋ=ˋ0.24, Pˋ=ˋ0.002), even after adjusting for the Sokolow每Lyon voltage (Pˋ=ˋ0.835). Additionally, the Cornell voltage was related to the inner/outer ratio of circumferential strain (betaˋ=ˋ0.17, Pˋ=ˋ0.033) after adjusting for the Sokolow每Lyon voltage (Pˋ=ˋ0.318). By contrast, the Sokolow每Lyon voltage was related to the relative wall thickness and E/e∩ on tissue Doppler imaging, even after adjusting for Cornell product. In conclusion, Cornell product and voltage were associated with longitudinal regional wall motion and with the transmurality of regional wall motion in the short axis direction
