Doppler超声时间指标评价高血压病、冠心病左室功能

采用Ｄｏｐｐｌｅｒ超声测量ＣＨＤ、ＨＤ、ＨＣＤ－ＣＨＤ及ｓ四组ＡＴ、ＥＴ、ＡＴ／ＥＴ、ＩＣＴ、ＰＥＰ／ＥＴ、ＰＥＰ、ＩＶＲＴ、ＡｃＴＥ、ＡｃＴＥ／ＭＶＯＴ，结果ＣＨＤ、ＨＤ、ＨＣＤ－ＣＨＤ三组ＩＶＲＴ明显升高（Ｐ＜０．０１），ＨＤ、ＣＨＤ与ＨＣＤＣＨＤ之ＩＶＲＴ差异有显著性（Ｐ＜０．０１），ＮＳ、ＣＨＤ、ＨＤ与ＨＣＤ－ＣＨＤ组ＰＥＰ／ＥＴ、ＩＣＴ、ＰＥＰ差异均有显著性（Ｐ＜０．０５），ＨＣＤ－ＣＨＤ组ＰＥＰ／ＥＴ、ＩＣＴ、ＰＥＰ值升高，ＮＳ、ＨＤ与ＣＨＤ、ＨＣＤ－ＣＨＤ、ＡＴ／ＥＴ差异有显著性（Ｐ＜０．０５），ＣＨＤ及ＨＣＤ－ＣＨＤ组ＡＴ／ＥＴ下降，ＨＲ、ＡＴ、ＥＴ、ＡＣＴＥ各组间差异均无显著性（Ｐ＞０．０５），Ｄｏｐｐｌｅｒ超声时间指标评价左室功能具有一定价值。

Time Index of Doppler Supersonic Device in the Estimation of the Function of Left Ventricle in the Cases With Hypertension or Coronary Heart Disease.

The AT, ET, AT/ET, ICT, PEP/ET,PEP, IVPT, AcTE and AcTE/MVOT of the four groups: the CHD group, HD group, the HCD-CHD group and the NS group were by Doppler Supersonic device. The results showed that the IVRT rose markedly in the CHD, HD and HCD-CHD groups (P<0.01). The difference of IVRT between HD, CHD and HCD-CHD groups was groups was of significance(P<0.01). The difference of PEP/ET, ICT and PEP between the four groups was significant(P<0.05). The values of PEP/ET, ET and PEP were raised in camparison with that of the normal group. The difference of AT/ET between in four groups was also of significance (P<0.05). The difference of HR, AT, ET and AcTE was of no signifcance (P>0.05). The AT/ET in the CHD and HCD-CHD groups decreased. All these suggest that time index of Doppler Supersonic device is of value in estimating the function of left ventricle.
