| 摘 要： | 目的探讨三平面基础上应用定量组织速度成像技术（QTVI）评价病毒性心肌炎（VMC）儿童左室内非同步运动的临床意义。方法正常儿童30例,VMC患者32例,每个受试者在实时三维成像的基础上获得标准的心尖四腔、两腔和三腔心切面,采集左心室6个壁的基底段、中间段、心尖段共18个位点的QTVI图像,测量各位点QRS波起点至收缩期峰值速度和舒张早期峰值速度的时限（Ts和Te）,计算左心室同一个壁内3个节段间Ts最大差值和Te最大差值（Intra-ΔTsI、ntra-ΔTe）以及同一个节段内6个壁之间Ts最大差值和Te最大差值（Inter-ΔTsI、nter-ΔTe）以及左心室18个节段Ts最大差值和Te最大差值（Max-ΔTs、Max-ΔTe）。结果 VMC组Intra-ΔTsI、ntra-ΔTe、Inter-ΔTsI、nter-ΔTe、Max-ΔTs、Max-ΔTe均较正常组延长。结论 VMC患儿左室内存在明显的非同步运动。

| Abstract: | Objective To evaluate the clinical value of inner-ventricular asynchorny in the children with viral myocarditis(VMC)using Quantitative tissue Velocity Imaging(QTVI) and Real-Time Three-Dimensional Echocardial(RT-3DE).Methods 30 normal children and 32 children with VMC were studied on QTVI and RT-3DE.the regional velocity profiles in 18 segmentsof left ventricular at LV apical four-chamber and two-chamber views were obtained.The time from onset of QRS complexes to peak velocity during systole and early diast... |
