No worries: No you shouldn't worry at all. It's a normal variation. As long as his slow rate was while resting/ sleeping his holter ranges were fine also.

Ask questions: A sinus arrhythmia is not an unusual finding even in a child and often results in fluctuating heart rates. It is not usually a concern unless the heart rate is too high which can give symptoms and could potentially impact ability to exercise. Ask provider for more specific information regarding ability to exercise and if any other intervention is needed.
