摘要
心功能早期损害监测与评估对肿瘤患儿治疗方案调整和预后评估有非常重要的意义。本文采用脉冲多普勒（PWD）和组织多普勒（TDI）方法对0．5～14岁儿童左心功能早期损害进行了监测，测定并比较了80例儿童的各项主要指标。研究表明化疗组肿瘤患儿的二、三尖瓣环血流频谱测值较对照组，具有显著差异。相比PWD，TDI方法能够更及时、客观、准确地实现儿童早期心功能损害监测评估的目标，可应用于肿瘤患儿心功能损害的早期识别。
The early damage detection and evaluation are of great significance in treatment and prognosis to the left ventricular function for children with tumor. In this paper, it is reported that the early damage of the left ventricular function was observed by pulsed wave Doppler （PWD） and tissue Doppler imaging （TDI） in our laboratory. Eighty children half a year to fourteen years old were included in this study. The cardiac function indices in chemotherapy group and control group were measured and compared. The results showed that there was significant difference in mitral and tricuspid annulus flow spectrum between the two groups. Compared with PWD,TDI is more prompt, ob jective and accurate in detecting early damage of left ventricular function in children with tumor. And TDI is a good method for early identification of ventricular function damage in children with tumor.
