运动心脏心肌收缩成分缩短加速度的生理意义

Physiologic Significance of Myocardial Contractile Element Shorting Acceleration of Athlete'Heart

本文首次较全面论述了心肌收缩成分缩短加速度这一类精确地、敏感地，在更深层次上反映心肌收缩性能的指标在运动心脏功能研究中的生理意义，详细探讨了心肌收缩成分缩短加速度类指标提出的背景、测量原理，曲线波型特点及参数值．为这类指标在运动性心脏心肌收缩性能的研究中的应用，提供了基础参考资料。

The acceleration of myocardial contractile element shorting is a new index of evaluating myocardial contractility. This paper first discusses the physiologic significance, background, principle of measurement and its normal value. The article supplies new reference to apply the index of myocardial contractile element shorting.
