摘　　要：目的:研究急性病毒性心肌炎(AVMC)患者肺静脉血流(PVF)的超声特征,评估AVMC患者左室舒张功能的变化。方法:使用HP-5500型彩色多普勒超声诊断仪,对26例AVMC患者(AVMC组),19例正常人(对照组)的右上肺静脉的心房收缩逆向A波(PVF-A)和二尖瓣血流频谱进行对照研究。结果:AVMC组的PVF-A波速率显著高于对照组,(40.41±7.85)cm.s-1对(26.12±3.12)cm.s-1,P<0.001。在E/A比值正常的AVMC1组,PVF-A波速率也显著高于对照组,(37.72±9.91)cm.s-1对(26.12±3.12)cm.s-1,P<0.01。结论:测定AVMC患者的PVF-A波速率能敏感评估左室舒张功能。Objective： To evaluate the characteristic of pulmonary venous flow （PVF） in the assessment of left ventricular dias tolic functicn （LVDF） in patients with acute viral myocarditis（AVMC）. Methods： Peak revevers upper right PVF A wave （PVFA） velocity at atrial contraction and mitral flow （MIF） were measured with Doppler echocardiography in 26 patients with AVMC and 19 age matched healthy controls. Results： The PVF A velocity was significantly higher not only in all patients with AVMC than in all controls （40.41 ± 7.85）cm·s^-1 vs （26.12± 3.12）cm·s^-1, P〈0. 001 ,but also in subgroup patients than controls with normal E/A ratio （37.72 ± 9.91 ）cm·s^-1 VS（26.12 ± 3.12）cm·s^-1 , P〈0. 01. Conclusion： PVF A velocity is a sensitive index to assess LVDF in patients with AVMC.
