摘要 目的运用M型超声心动图检测40例先天性心脏病(CHD)患者的室间隔(IVS)运动M型曲线,无创评估先天性心脏病患者的肺血管阻力(PVR)和平均肺动脉压(PAMP)。方法根据室间隔的不同运动状态,将收缩期早期距离基线的最大前向位移定义为a,将舒张早期距离基线的最大后向位移定义为b。将a/b≥1.0定义为A组,将a/b<1.0定义为B组。两组患者均在接受超声心动图检查的当天进行心导管检查。结果 A组的PVR和PAMP明显高于B组患者(P<0.05)。组A的室间隔M型曲线提示A组患者存在较高的PVR和PAMP。结论根据室间隔运动M型曲线可以快速且无创地评估先心病患者是否PVR或PAMP升高,在先心病患者的诊断治疗上具有实际意义。
