Children may die suddenly and unexpectedly following cardiac surgery, even while receiving intensive medical care, when current noninvasive and invasive monitoring techniques fail to warn us of an impending problem. This report examines the efficacy of heart-rate spectral analysis, a noninvasive method that quantitates the beat-to-beat fluctuations in heart rate, in characterizing and tracking cardiovascular regulatory status. A total of 45 heart-rate fluctuation studies, performed on selected patients, at the bedside, using heart-rate spectral analysis, were retrospectively correlated with clinical events. The spectral pattern of 18 patients who sustained a cardiac arrest differed significantly from the others in the study group (p less than 0.0001).
儿童在心脏手术后可能会突然意外死亡，即使在接受重症医疗护理时也是如此，此时当前的非侵入性和侵入性监测技术未能向我们警示即将出现的问题。本报告探讨心率频谱分析（一种定量心率逐搏波动的非侵入性方法）在表征和跟踪心血管调节状态方面的功效。对选定患者在床边使用心率频谱分析进行的总共45项心率波动研究，与临床事件进行了回顾性关联分析。研究组中18例发生心脏骤停的患者的频谱模式与其他患者有显著差异（p<0.0001）。
