| [摘要] 目的 常规二维及实时三维超声心动图(RT-3DE)研究左室假腱索（LVFT）患者心脏同步性的改变及其临床意义。方法 选取我院2016年1月~2018年6月间经超声心动图检查确诊LVFT组患者173例，年龄36.7±8.44岁，女性23例；按性别、年龄匹配选择同期健康体检无LVFT的150例作为对照组，年龄35.84±7.53岁，女性20例。二维超声心动图详细记录患者LVFT的大小、连接方式及走形，脉冲多普勒及实时三维超声心动图评价左房室间、左右心室间及左室内同步性。比较两组间同步性的差异及其与假腱索形态的相关性。结果 LVFT患者在左室内不同步方面较无LVFT者存在统计学差异(P<0.05)，对LVFT的大小、连接方式及走形进一步分类，多元回归显示LVFT的连接方式与同步性指标左室16节段达到最小收缩容积时间的标准差（TMSV16-SD）独立相关(P<0.05)。结论 LVFT的连接方式是影响心脏左室内同步性的重要因素，具有良好的临床参考价值。 |

| [Abstract] Objective To study the changes of cardiac synchronization and its clinical significance in patients with left ventricular false tendons(LVFT) using routine two-dimensional and real-time three-dimensional echocardiography(RT-3DE).Methods 173 patients confirmed by echocardiography, aged 36.7±8.44 years old and 23 females, were detected continuously in our hospital from January 2016 to June 2018 as the LVFT group, and 150 cases without LVFT, aged 35.84±7.53 years old and 20 females, were selected as the control group during the same period of physical examination according to gender and age matching. Two-dimensional echocardiography recorded the size, connection mode and direction variation of the patient''s LVFT in detail, and pulse doppler and real-time three-dimensional echocardiography evaluated the left atrioventricular, interventricular and left ventricular synchronization, then compared the difference of synchronicity between the two groups and its correlation with the morphology of LVFT. Results There were statistically significant differences in left ventricular dyssynchrony between LVFT patients and those without (P<0.05), and further classification of LVFT''s size, connection mode and direction variation showed that the connection mode was independently related to standard deviation of time to minimum systolic volume in left ventricle 16 segments（TMSV16-SD）by multiple regression (P<0.05).Conclusion The connection mode of LVFT was an important factor which affecting left ventricular synchronization, so it has good clinical reference value. |
