The degree of fetal heart rate dependency of pulsatility index measurements in the fetal descending aorta, internal carotid artery, and umbilical artery was studied relative to quiet and active sleep states in normal and growth-retarded fetuses at 37-38 weeks of gestation. In all vessels an inverse relationship between pulsatility index and heart rate was established. The degree of this inverse relationship varies proportionally with the level of peripheral vascular resistance in the vessels studied.
在妊娠37 - 38周时，针对正常胎儿和生长受限胎儿，研究了胎儿降主动脉、颈内动脉和脐动脉搏动指数测量值对胎心率的依赖程度与安静和活跃睡眠状态的关系。在所有血管中均建立了搏动指数与心率之间的反比关系。这种反比关系的程度与所研究血管的外周血管阻力水平成比例变化。
