Heart rate variability and thoracal respiratory movements were examined in two babies aged six months during eight hour polysomnographic recordings. Computer-assisted analysis in the time and frequency domain were performed to investigate the mechanisms underlying cardiorespiratory control. Coherence and phase relation between cardiac cycles and respiration were investigated in detail. Both methods demonstrated that during quiet sleep (stage 3/4), the cardiorespiratory coupling was significantly increased as compared to active sleep (REM sleep).
在两个6个月大的婴儿进行8小时多导睡眠图记录期间，对心率变异性和胸部呼吸运动进行了检查。进行了时域和频域的计算机辅助分析，以研究心肺控制的潜在机制。详细研究了心动周期与呼吸之间的相干性和相位关系。两种方法均表明，与活跃睡眠（快速眼动睡眠）相比，在安静睡眠（3/4期）期间，心肺耦合显著增加。
