The aim of this study was to investigate the clinical value of the apex beat and two ECG voltage criteria in the detection of left ventricular hypertrophy (LVH) while considering two distances, from the heart to the inner chest wall and to the chest surface, measured by using multislice CT (MSCT). The study population consisted of 151 patients clinically judged as requiring MSCT angiography. The apex beat was palpated with patients in the supine. Sokolow-Lyon voltage and Cornell voltage to detect LVH were determined. The pattern of sustained or double apical impulse and Cornell voltage had higher specificity as an indicator of LVH than Sokolow-Lyon voltage. Furthermore, the distance to the inner chest wall was negatively correlated with left ventricular end-diastolic volume and mass. Contrarily, the distance to the chest surface was correlated with the body mass index. Multivariate analyses revealed that the pattern of sustained or double apical impulse showed a stronger association with the distance to the inner chest wall than to the chest surface, but Sokolow-Lyon voltage was associated with the distance to the chest surface. Among the screening tests for excluding patients with LVH, Cornell voltage or the apex beat would be better than Sokolow-Lyon voltage because these are less dependent on body size and have higher specificity.
