This study examined the existence of direct maternal-infant physiological relatedness in respiratory sinus arrhythmia (RSA) when the infant was age 1, 2, 4, 8, and 12 weeks. We instructed mothers to breathe at 6, 12, 15, 20, and 6 cycles per minute while their infants lay on their body. The mother-infant ECG and respiration were registered and video recordings were made. RR-interval (RRI), respiration rate (fR) and RSA were calculated and mother-infant RSA response-patterns were analyzed. The results revealed that infants adjusted their RSA levels to their mothers' levels during the first 2 months of life, but not at 3 months of age, which could be interpreted as a continuing intra-uterine effect. The attenuation between 2 and 3 months could be a reflection of the 2-month developmental shift of social orientation.
本研究调查了婴儿在1、2、4、8和12周龄时，母婴在呼吸性窦性心律不齐（RSA）方面是否存在直接的生理关联。我们指导母亲们在婴儿趴在她们身上时，分别以每分钟6、12、15、20和6个周期的频率呼吸。记录母婴的心电图和呼吸情况，并进行录像。计算RR间期（RRI）、呼吸频率（fR）和RSA，并分析母婴RSA反应模式。结果显示，婴儿在出生后的前两个月会将其RSA水平调整至与母亲相同，但在3个月大时则不会，这可以解释为子宫内效应的持续影响。2至3个月之间的衰减可能反映了社会取向在2个月时的发育转变。
