【摘要】 目的与方法 :运用M型超声心动图探讨高血压病向心性肥厚程度与收缩功能的相关关系。结果 :收缩功能 (心率校正的FS ,y轴 )与向心性肥厚程度 (左室重量与左室容积之比LVM /LVCV ,x轴 )的呈曲线相关关系 ,其曲线方程为^y=- 31.139x2 +146 .192x1- 130 43。LVM /LVCV为 2 .35时 ,其心率校正的FS为最大 41.6 3。结论 :在心肌肥厚的初期 ,心肌肥厚使左心室的收缩功能起代偿性增强 ,当心肌增厚到一定程度时 ,左室收缩功能随心肌进一步肥厚而呈下降趋势。更多还原

【Abstract】 Objective and Method:To assess the correlation between degree of left ventricular(LV) concentric hypertrophy and systolic function. Results:There was curve correlation between systolic function(FS corrected by heart rate) and degree of left ventricular concentric hypertrophy(ratio of LV mass to cavity volume, LVM/LVCV). The curve correlation equation was:^y=-31.139 x 2+146.192 x 1-130 43. When LVM/LVCV ratio was 2.35, FS corrected by heart rate reached its maximum: 41.63. Conclusions:In the early stage of LV concentric hypertrophy, the LV systolic function enhanced, however when LV concentric hypertrophy was developed to a certain degree,the decompensation of LV systolic function ensued.更多还原
