The aim of this study was to investigate the relationship between left ventricular mass (LVM) and interatrial conduction delay (CD) measured by tissue Doppler echocardiography. In enrolled 66 hypertensive patients, positive correlation between interatrial CD and LVM index (r = 0.32) was detected. Meanwhile, intra-atrial CD was correlated to early diastolic tissue Doppler mitral annular velocity measured from septum (r = 0.34), tricuspid annular velocity (r = 0.29), and left atrial volume index (r = 0.26). By using stepwise linear regression analysis, LVM index was determined as an independent predictor of interatrial CD.
本研究旨在探讨组织多普勒超声心动图测量的左心室质量（LVM）与房间隔传导延迟（CD）之间的关系。在纳入的 66 例高血压患者中，检测到房间隔 CD 与 LVM 指数之间存在正相关（r = 0.32）。同时，房间内 CD 与从间隔测量的二尖瓣环组织多普勒早期舒张速度（r = 0.34）、三尖瓣环速度（r = 0.29）和左心房容积指数（r = 0.26）相关。通过逐步线性回归分析，LVM 指数被确定为房间隔 CD 的独立预测因子。
