摘要

从年轻和年老的比格犬群中获得的数据表明，衰老的比格犬心脏的特点是收缩功能较低(通过发达压力和最大压力随时间变化的速率来测量)，收缩持续时间较长，并且在给定压力下通过正弦强迫技术测量的动态刚度增加。

Contraction duration and diastolic stiffness in aged canine left ventricle.

The data obtained from groups of young and old beagles demonstrate that senescent beagle hearts are characterized by lower contractile function as measured by developed pressure and maximal rate of pressure change with time, by longer contraction duration, and by increased dynamic stiffness per given pressure as measured by the sinusoidal forcing technique.
