本文采用无创性检测方法，观察３１例轻症心肌炎患者的心功能变化。结果发现心舒功能的减退比心缩功能更明显。心舒期缓慢充盈波与快速充盈波时程比（ＳＦＷ／ＲＦＷ）显著增加（Ｐ＜０．０１），房缩波波辐增大、时程延长（Ｐ＜０．００１）；心缩期除左室射血时间（ＬＶＥＴ）缩短外（Ｐ＜０．０５），其余指标及泵功能均无显著改变，研究提示，应用无创性心功能检测方法，注意心舒功能的改变，可为轻症心肌炎的临床诊断和病情监护提供参考。
In this paper, noninvasive detection methods were used to observe the changes of cardiac function in 31 patients with mild myocarditis. The results showed that cardiac function decline more obvious than systolic function. Compared with SFW / RFW, the systolic and diastolic velocities of systolic and diastolic phases were significantly increased (P <0.001 and P <0.001) In addition to shortening left ventricular ejection time (LVET) (P <0.05), the remaining indicators and pump function were not significantly changed, the study suggests that the application of noninvasive cardiac function test method, pay attention to changes in cardiac function may be light Myocarditis and clinical diagnosis of disease monitoring provide a reference.
