This study compared the non-quiver with the quiver technique for identifying the end-systolic and end-diastolic endocardium of the fetal right ventricle (RV) and left ventricle (LV) used for speckle-tracking analysis. Bland-Altman and t test analyses showed no significant differences in measurements between the techniques for the RV and LV. The difference in the time required to perform the non-quiver analysis was significantly longer (P < .001) for the RV and LV than the quiver technique. The quiver technique allows the examiner to efficiently identify the endocardial borders of the fetal heart compared with the non-quiver method.
本研究比较了非弹丸式与弹丸式技术，以识别用于斑点追踪分析的胎儿右心室（RV）和左心室（LV）的收缩末期和舒张末期心内膜。Bland-Altman 和 t 检验分析显示，两种技术在 RV 和 LV 的测量值之间无显著差异。与弹丸式技术相比，非弹丸式分析所需的时间明显更长（P<0.001），无论是 RV 还是 LV 都是如此。与非弹丸式方法相比，弹丸式技术可使检查者更有效地识别胎儿心脏的心内膜边界。
