Key result
Fetal cardiac arrhythmias were associated with evidence of acidosis during labor and at the time of delivery in three reported cases.
Fetal cardiac arrhythmias, such as nodal extrasystoles, nodal tachycardia, and auricular flutter, can be associated with fetal acidosis during labor and delivery.
Answers are grounded in this paper and cite their sources.
Fetal arrhythmias with acidosis in case reports is hypothesis-generating; should not change practice without prospective validation.
Summary: Three cases of fetal cardiac arrhythmia (one of nodal extrasystoles, one of nodal tachycardia and one of auricular flutter), are described in which there was evidence of acidosis during labour and/or at the time of delivery. The subsequent progress of these infants is described and the findings discussed in relation to previous observations on fetal cardiac arrhythmias.
