| 摘 要： | 目的：评价运动负荷下左室舒张功能的变化。方法：采用彩色多普勒超声技术，采集分析了24例耐力项目大学生运动员、普通大学生安静状态、定量负荷、极量负荷下二尖瓣血流频谱及相关参数。结果：运动与安静状态时心率(HR)与二尖瓣血流速度积分(TVI)、E／A值呈负相关；二尖瓣平均压差(MEAN GRAD)和A峰值存在明显差异，A峰与E峰可出现融合现象。结论：负荷运动可使心脏左室舒张功能产生适应性反应，多普勒超声可低创伤地评价其变化。

| Abstract: | Objective:To evaluate left ventricle diastolic function with load experiment.Methods:In quiet state,after fixed load exercise and maximum exercise,24 college endurance game athletes and college students' transmitral flow volumes and relative parameters were measured and analysed.Results:HR has negative relativity with TVI and E/A.After load experiment MEAN GRAD and A changed obviously.A and E mixed together.Conclusion:With load increased,left ventricle diastolic function resulted adaptation.Doppler ultrasonography can evaluate left ventricle diastolic function's change unwounded. |
