目前利用超声心动图评价心脏收缩或舒张功能的指标很多,但大多依赖于心脏的几何形态或心脏瓣膜返流,并且多为单一评价心脏的收缩功能或舒张功能。许多研究证实,心脏收缩功能不全和舒张功能不全往往在一定程度上是同时发生的,单一估测心脏收缩或舒张功能指标的准确性及敏感性较?
At present, there are many indexes for evaluating systolic or diastolic function by echocardiography, but most of them rely on the geometry of the heart or the valvular regurgitation of the heart, and more often they evaluate the systolic or diastolic function of the heart. Many studies have confirmed that systolic dysfunction and diastolic dysfunction often occur to some extent at the same time, a single assessment of cardiac function indicators of systolic or diastolic accuracy and sensitivity than?
