目前的研究证明肥厚性心肌病存在原发性左室舒张功能异常,片可导致心泵功能障碍,最后发生充血性心衰.了解肥厚性心肌病左室舒张功能异常发生的机理和临床表现,对提高此病的诊断和治疗水平是很重要的。发生的机理松弛和顺应与心动周期的关系如下:从上表可以看出,心肌松弛开始于喷血的后期,终止于快速充盈期末;此后开始左室的顺应,它于下一次心动周期开始而终结.由此可见,左室的舒张功能取决于心肌的松弛性能和心室的顺应性能.一、松弛性能异常 The current study shows that hypertrophic cardiomyopathy exists abnormal primary left ventricular diastolic dysfunction, slice can lead to cardiac pump dysfunction, and finally congestive heart failure.Learn to understand the pathogenesis and clinical manifestations of left ventricular diastolic dysfunction in hypertrophic cardiomyopathy, To improve the diagnosis and treatment of the disease level is very important. The mechanism of relaxation and compliance occurs in relation to the cardiac cycle as follows: It can be seen from the above table that myocardial relaxation begins at the late stage of spurting and ends at the rapid filling stage; thereafter, left ventricular compliance begins, which begins at the next cardiac cycle The end of this shows that left ventricular diastolic function depends on the relaxation of myocardial performance and ventricular compliance. First, the relaxation of abnormal performance
