A baby born at 37 weeks’ gestation was noted to have premature beats in utero. He was born in good condition. The premature beats were heard intermittently in the first few hours of life. There was no significant family history. He remained well with normal observations and was discharged home after reassurance was provided. At 9 days of age an irregular pulse was noted again during an assessment for jaundice.
