| Abstract: | Patterns of circadian and ultradian rhythms in the heart rate(HR) are described in a full-term baby with birth asphyxia and convulsions.A 24h HR recording was carried out at the age of 1, 15, 56, 289, and 295 days;West syndrome diagnosis was made when the patient was 3 months old. The HRshowed no circadian rhythm in the follow-up, whereas it is known that thecircadian rhythm appears in healthy infants at the age of 1 month and remainsthereafter. This observation may be an indirect indicator of the interferenceof West syndrome with centers of neurological maturity. (ChronobiologyInternational, 17(4), 591–595, 2000) |
