本研究检查了学龄前儿童在长时间注意期间三种心律失常（血管紧张素-肾素血管紧张素[ARV]，Traube-Hering-Meyer [THM]和呼吸性窦性心律失常[RSA]）的变化。在一项纵向研究中，从3岁、4岁和5岁儿童的静息基线和5分钟注意力状态下收集心电图数据。大多数受试者在长时间注意时ARV和THM节律性降低。RSA节律性没有一致性变化。结果在所有三个年龄重复。ARV和THM效应量分别为大和中等。只有ARV的下降与注意力的持续时间相关。
This study examined the changes in three cardiac rhythmicities (angiotensin‐renin vasomotor [ARV], Traube‐Hering‐Meyer [THM], and respiratory sinus arrhythmia [RSA]) during prolonged attention in preschool children. Electrocardiogram data were collected from children during resting baseline and a 5‐min attention condition at ages 3, 4, and 5 years in a longitudinal study. The ARV and THM rhythmicities decreased during prolonged attention for most participants. The RSA rhythmicity did not change consistently. The results were replicated at all three ages. The ARV and THM effect sizes were large and moderate, respectively. Only the ARV decrease correlated with duration of attention.
