前言 已知对外来电刺激作出反应时,人心律发生相位重整。许多作者提出,冲击性加速度后也有发生心律相位重整的可能性。但没有经过严密的研究。 方法 大约50名年轻、健康的男性志愿者暴露于—X,+Y和+Z轴向冲击力。根据峰值加速度的幅度从9G/s～15G/s,选择分析了200次以上的冲击。包括高和低的加速度增长率的试验。 结果 尽管每次冲击刺激和心搏周期的相位并不同步,在整个周期中大量的试验产生了冲击活动的均匀分布。发现相位重整的发生依靠于冲击力的大小及轴向。观察到了偶数和奇数相位重整的迹象。结论 人心搏周期的相位重整确实会随全身冲击加速度而发生。这种重整的假定
Preface Known to external electrical stimulation to respond, the human heart rhythm phase reformation. Many authors suggest that there is also the potential for cardiac arrhythmia after impact acceleration. But it did not go through rigorous research. Methods Approximately 50 young, healthy, male volunteers were exposed to -X, + Y, and + Z axial impact. According to the magnitude of peak acceleration from 9G / s ~ 15G / s, the impact of more than 200 times was analyzed and selected. Tests including high and low acceleration growth rates. Results Although the phase of each shock and heart cycle was not synchronized, a large number of tests throughout the cycle produced a uniform distribution of impact activity. Found that the occurrence of phase relying on the impact of the size and axial. Observed signs of even and odd phase reforming. Conclusions The phase reordering of the human cardiac cycle does occur with the acceleration of the whole body. This restructuring assumption
