对心脏功能的研究,既往大多着重于收缩功能方面,而对心脏舒张期的性能,尤其是对心室舒张期顺应性这一生理学概念,常常被忽视。七十年代以后,许多学者开始注意设计各种方法来测定心室舒张期的顺应性。心室舒张期的顺应性,可理解为“扩张性”或“弹性”一类的性质。它代表心室容积变化(dv)与压力变化(dp)之间的关系,用dv/dp来衡量。dv/dp大,即顺应性大,反之则小。
The study of cardiac function, the past mostly focused on the aspects of systolic function, and diastolic performance, especially the physiological concept of ventricular diastolic compliance, are often overlooked. After the 1970s, many scholars began to pay attention to designing various methods to determine the compliance of ventricular diastolic phase. Compromise of ventricular diastolic, can be understood as “expansion” or “elasticity” of a nature. It represents the relationship between changes in ventricular volume (dv) and changes in pressure (dp), measured in dv / dp. dv / dp large, that is, large compliance, otherwise small.
