应用Ｍ型、二维超声心动图和脉冲多普勒超声心动图，评价糖尿病人的左室舒张功能。结果表明：①左房收缩引起的ＡＶ平面位移增加；心房收缩期ＡＶ平面位移与全舒张期位移的比值大于５０％（Ｐ＜０．０１）；②二尖输血流Ａ峰最大流速大于Ｅ峰最大流速；Ａ／Ｅ比值大于１（Ｐ＜０．０１）；③多普勒二尖瓣血流Ａ／Ｅ值与左房影响的ＡＶ平面位移存在良好的相关性（ｒ＝０．８１）．提示定量检测ＡＶ平面位移，可作为左室舒张功能评价的一项新的超声心动图指标。
M-type, two-dimensional echocardiography and pulsed Doppler echocardiography were used to evaluate left ventricular diastolic function in diabetics. The results showed that: ① AV plane displacement caused by left atrial contraction increased; the ratio of AV plane displacement and total diastolic displacement in atrial systole was more than 50% (P <0.01); ②maximum flow velocity of A peak in mitral blood flow was greater than E peak (P <0.01). The A / E values of Doppler mitral flow had a good correlation with AV plane displacement of left atrium (r = 0.81) . Prompt quantitative detection of AV plane displacement, can be used as a new echocardiographic evaluation of left ventricular diastolic function.
