HRI comprised transient bradycardia and tachycardia, which first developed on day 14 and 16 in most embryos, respectively. Transient bradycardia increased in frequency and magnitude with embryonic development and occurred over periods of up to 30min in some embryos. MHR was maximal on around days 14-15 and thereafter decreased to about 250-260bpm on days 16-18. Baseline HRV, which is an oscillation of the MHR baseline, occurred as HR decreased from days 15-16 and became predominant on days 17-18. The magnitude of the baseline oscillations reached up to 50bpm in some embryos and the period ranged between about 40-90min (ultradian rhythm). A circadian rhythm of MHR was not found in late chick embryos. On days 18-19, embryonic activities were augmented and then breathing movements began to occur, disturbing ACG signals and thus making it difficult to measure the HR. Instead, the development of breathing activities was recorded. Breathing frequency was irregular at first and then increased to a maximum of about 1.5Hz prior to hatching.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_77_description_8":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"特集 :
