  • the clinical value of Apex Beat and electrocardiography for the detection of left ventricular hypertrophy from the standpoint of the distance factors from the heart to the chest wall a multislice ct study
    Hypertension Research, 2011
    Co-Authors: Shoichi Ehara, Takuhiro Okuyama, Nobuyuki Shirai, Yoshiki Matsumura, Junichi Yoshikawa, Kenji Matsumoto, Minoru Yoshiyama
    Abstract:

    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.

    Abstract:

    Summary Objectives Although physicians frequently perform palpation of the Apex Beat to evaluate left ventricular (LV) size and hypertrophy, the clinical significance of Apex Beat palpation is still unclear. The introduction of multislice computed tomography (MSCT) has enabled assessment not only of coronary stenoses but also LV volume, mass, and distance from heart to chest wall. The aim of this study was to evaluate the relationships among presence, location, and sustained or double apical impulse of Apex Beat and LV function, volume, mass, and distance from heart to chest wall determined by MSCT. Methods and results The study population consisted of 200 consecutive patients clinically indicated for MSCT angiography for coronary artery evaluation. Apex palpation was performed with the patients in the supine and left lateral decubitus positions. Multivariate analysis revealed that LV mass index (p  Conclusion Palpation of the Apex Beat is a sensitive diagnostic maneuver for excluding patients with increased LV mass. We believe that our observations have important implications for bedside clinical examination.
