摘要

为了评估缺铁贫血婴儿睡眠期间自主神经系统的发育，我们应用离散小波变换进行心率变异性分析。该方法在低频域提供合适的频率分辨率，这是生理兴趣域。缺铁婴儿和对照组婴儿在安静和活跃(REM)睡眠中均表现出显著差异，表明贫血婴儿存在自主神经功能障碍或延迟。

Discrete wavelet transform applied to heart rate variability analysis in iron-deficient anemic infants

To assess the autonomic nervous system development in iron-deficient anemic infants during sleep, we applied the discrete wavelet transform to perform heart rate variability analysis. The method provides suitable frequency resolution in the low-frequency domain, which is the domain of physiological interest. Significant differences between iron-deficient and control infants are shown in both quiet and active (REM) sleep, suggesting an autonomic dysfunction or delay in anemic infants.
