| 摘 要： | 目的：探讨等容舒张期左室平均压力变化率评价左室舒张功能的价值。方法： 采用多普勒超声及计算机技术测量５０ 例二尖瓣返流患者左室舒张功能的指标。结果： 等容舒张期左室平均压力变化率（－ ｄｐ／ｄｔｍ ｅａｎ） 与左室压力最大下降速率（－ ｄｐ／ｄｔｍ ａｘ）显著相关（ｒ＝ ０．８７），与左室心肌松弛时间常数中度相关（ｒ＝ ０．５６）；以－ ｄｐ／ｄｔｍ ａｘ＜ １５００ｍｍ Ｈｇ／ｓ定为左室舒张功能异常，－ ｄｐ／ｄｔｍ ｅａｎ＜ １２００ｍ ｍ Ｈｇ／ｓ判断左室舒张功能异常的敏感性为８５％ ，特异性为１００％ 。结论： － ｄｐ／ｄｔｍ ｅａｎ 可准确、无创性评价左室舒张功能。

| Abstract: | Objective:To evaluate the new method for noninvasive measurement of left ventricular diastolic function.Methods:The parameters of the left ventricular diastolic function were measured by Doppler echocardiography and computer techniques in 50 patients.Results:There were high correlation between dp/dt mean and dp/dt max( r =0 87)and good correlation between dp/dt mean and the time constant of left ventricular relaxation(T)( r =0 56).Conclusion:dp/dt max can be used to evaluate the left ventricular diastolic function. |
