Key result
Submersion during infant swimming elicited an immediate reflex bradycardia, decreasing heart rate by an average of 25% (p < 0.0001), which remained evident in infants over 6 months of age.
Why the study?
Does submersion during infant swimming induce a bradycardic response in full-term healthy infants?

May warrant monitoring during infant swimming classes; leaves open clinical relevance and need for prospective safety studies.

Does submersion during infant swimming induce a bradycardic response in full-term healthy infants?
Effect estimate: 25% decrease
p-value: p=< 0.0001
The study demonstrates that full-term healthy infants exhibit a clear, vagally mediated bradycardic diving response during submersion that persists beyond 6 months of age.
Goksör et al. (2002) conducted an observational in Healthy infants (n=36). Submersion during infant swimming was evaluated on Change in heart rate during submersion (25% decrease, p=< 0.0001). Submersion during infant swimming elicited an immediate reflex bradycardia, decreasing heart rate by an average of 25% (p < 0.0001), which remained evident in infants over 6 months of age.
