| 摘 要： | 目的应用实时三维超声技术评价急性病毒性心肌炎患儿左心室的舒缩功能，观察左室心肌收缩同步性。方法应用Philips iE33超声诊断仪对病毒性心肌炎患儿（VMC组）及正常儿童（N组）进行二维超声心动图及实时三维超声心动图检查。结果ⅧC组左室壁16节段、12节段及6节段收缩末期最小容积时间（Tmsv）的标准差和最大差值（即Tmsv 16-SD，Tmsv16-Dif，Tmsv 12-SD，Tmsv12-Dif，Tmsv6-SD和Tmsv6-Dif）及其心率校正值均高于N组（P〈0．05）。结论急性病毒性心肌炎患儿在常规超声心动图检查未发现异常的情况下，应用实时三维超声心动图检测可早期发现左室壁局部收缩、舒张功能的减低及心肌收缩同步性的异常。

| Abstract: | Objective The research has applied three-dimensional echocardiography to detect and evaluate the children with viral myocarditis for the whole and regional systolic and diastolic function of left ventricular myocardial,and to observe the synchronous change of myocardial movement,which will provide credible basis for clinical diagnosis.Methods Philips iE33 and Q-Lab software were used in this study to examine 56 children with acute viral myocarditis (Group VMC) and 63 normal children(Group N) by traditional 2DE ,3DE.Results as to Tmsv16-SD,Tmsv16-Dif,Tmsv12-SD,Tmsv12-Dif,Tmsv6- SD,Tmsv6-Dif and revised heart rates,Group VMC is higher than Group N(P＜0.05).Conclusion This study showed that the children with acute viral myocarditis can be early examined by three-dimensional echocardiography,which can not be found by conventional echocardiography. |
