一般讲,人们对于心脏的收缩机能比较重视,而对心脏的舒张机能重视不足,甚至错误地认为舒张是一种被动过程,主动的收缩一停止,心脏就自然地被动舒张。其实,心脏舒张也是一种主动过程。心室舒张功能正常与否对心室收缩功能有着重要影响。左室舒张期压力与容积的关系可用顺应性来表示。因而左室顺应性可反映其舒张机能。
In general, people are more emphasis on the contraction of the heart function, and diastolic function of the heart, lack of attention, and even mistakenly think that relaxation is a passive process, the active contraction of a stop, the heart naturally passive diastolic. In fact, diastolic heart is also a kind of active process. Ventricular diastolic function is normal or not has an important impact on ventricular systolic function. The relationship between left ventricular diastolic pressure and volume can be expressed in terms of compliance. Thus left ventricular compliance can reflect its diastolic function.
