What is sinus bradycardia in an 8 yr old?

Answer 1

Sinus bradycardia in an 8-year-old refers to a slower than normal heart rate originating from the sinus node, typically defined as a resting heart rate of fewer than 60 beats per minute. It can be a normal variant in well-conditioned athletes or occur due to other factors like medication effects, increased vagal tone, or underlying medical conditions. While it may be asymptomatic in some children, in others, it can cause symptoms such as fatigue, dizziness, or fainting. Evaluation by a healthcare professional is necessary to determine the underlying cause and if treatment is needed.
