Changes in systolic time intervals during the work load point to the differences in their control mechanisms. The exponential decay of the parameters shows sinusoidal oscillations. The number of oscillations is short in cycle length and isometric contraction time; it is the greatest in the ejection period.
工作负荷期间收缩期时间间隔的变化表明其控制机制存在差异。参数的指数衰减呈现正弦振荡。周期长度和等长收缩时间的振荡次数较少；射血期的振荡次数最多。
