心脏舒张功能是指心肌扩张和容纳血液的能力,是主动的耗能过程。心脏疾患时心脏功能异常可表现为收缩或/和舒张功能异常,也可以表现为舒张功能异常而收缩功能正常。因此,要全面评定心脏功能单纯用收缩功能显然是不够的,必须同时评定心脏舒张功能。 Diastolic function refers to the ability of the heart to dilate and hold blood and is an active energy-consuming process. Cardiac dysfunction may be manifested as cardiac dysfunction, systolic and / or diastolic dysfunction, diastolic dysfunction and contractile function may be normal. Therefore, to fully assess the cardiac function simply with systolic function is clearly not enough, we must also assess cardiac diastolic function.
