| 摘 要： | 目的探讨心脏超声评价心脏收缩同步性的临床效果。方法选择2007年2月～2010年3月孤立性左束支传导阻滞患者36例为观察组，40例心电无异常的健康人为对照组，对所有试验者的心率（HR）及心脏超声指标LVEF、LVEDV、Tmsvl6一SD、Tmsvl6一Dif、Tmsv6一SD及Tmsv6一Dif进行单因素对比分析，然后对与心脏收缩同步性的相关因素进行Logistic多元回归分析。结果单因素分析提示观察组与对照组在HR、LVEF、LVEDV无明显差异（P〉0．05）；观察组与对照组在Tmsvl6一SD、Tmsvl6一Dif、Tmsv6一SD及Tmsv6一Dif存在明显差异（P〈0．05）。Logstic多因素回归分析显示Tmsvl6一SD、Tmsvl6一Dif、Tmsv6一SD及Tmsv6一Dif是评价心室收缩同步性的独立因素。结论超声心动能较准确地评价心室收缩的同步性，尽管左束支传导阻滞者的射血分数尚正常，但以超声心动为标准的心功能已有下降。

| Abstract: | Objective To evaluate the value of heart ultrasound to predict cardiac synchronicity. Methods 36 patients with left bundle branch block were chosen from February 2007 to March 2010 as the test group and 40 healthy people as the control group. The heart ultrasound data of all patients were analyzed with multiple logistic regression analysis. Results Compared with the control group, HR, LVEF, LVEDV in test group had no statistically significant difference （P〉 0.05 ）. Compared with the control group, Tmsvl6-SD, Tmsvl6-Dif, Tmsv6-SD and Tmsv6-Dif in test group had statistically significant difference （ P 〈 0.05 ）. Tmsvl6-SD, Tmsvl6- Dif, Tmsv6-SD and Tmsv6-Dif are independent factors for predicting cardiac synchronicity. Conclusion Heart ultrasound can evaluate the synchronization of the myocardium accurately. |
