组织多普勒分析是评价舒张功能的一种新型超声心动图检查方式。本文报道对1组15例心肌致密化不全患儿进行组织多普勒分析的结果。二维超声心动图检查显示只有8例患者的收缩功能降低。分析发现有7例患者的舒张功能发生改变:2例患者的全部节段均可见E波降低,3例患者的舒张功能障碍限于尖段和外侧段,其余2例患者的E波降低仅见于尖段。收缩功能障碍和舒张功能障碍之间存在强相关性:事实上,存在舒张功能障碍的所有患者亦表现出收缩功能的显著降低。 Tissue Doppler analysis is a new type of echocardiographic test to evaluate diastolic function. This article reports a group of 15 cases of myocardial densification in children with tissue Doppler results. Two-dimensional echocardiography showed only 8 patients with reduced systolic function. Seven patients had alterations in diastolic function: E wave reduction was seen in all segments of the two patients, diastolic dysfunction was limited to the tip and lateral segments in three patients, and E wave reduction was seen only in the other two patients segment. There is a strong correlation between systolic and diastolic dysfunction: in fact, all patients with diastolic dysfunction also show a significant reduction in systolic function.
