摘　　要：我们对16例轻型心肌炎患儿用心机械图系统观察了发病6～12个月内的左室功能。结果发现发病第一个月PEP、ICT延长,LVET缩短,PEP/LVET、ICT/LVET升高,与对照组差异显著或非常显著,其中以PEP、PEP/LVET改变最明显。经正规治疗,以上指标多于3～4个月内逐渐恢复,PEP由79±6ms缩至69±9ms,PEP/LVET由0.265±0.02降为0.188±0.02。DTI无显著改变。说明轻型心肌炎发病一个月内左室收缩功能有所下降,至病程第三、四个月逐渐恢复正常。In order to understand the left ventricnlar(LV)Performance in children with acute infectious myocarditis, systolic and diastolic time interval (STI. DTI)were measured by mechanocardiography in 16 Patients in the 1st.2nd 3rd-4th. 6th-12th month after the onset of the disease. The results showed that during the first month PEP. ICT prolonged, LVET shortened and PEP/LVET. ICT/LVET increased significantly as compared with the controls (P<0.05-0.001).Among them PEP. PEP/LVET changed more obviously. Aftel regular treatment, the above indices recovered gradually in 3-4 months, PEP shortened from 79±6ms to 69±9ms and PEP/LVET decrased from 0.265±0.02 to 0.188±0.02 within 6-12 months (P<0.01). DT1 changed insignificantly.These results indicate that the LV systolic performance diminishes in the early stage of myocarditis though without clinical manifestations and recovers within 3-4 months.
