Doctor's answer (1)
Dr. Zhou Xiaofeng
Sinus arrhythmia in children usually refers to an irregular heart rhythm originating from the sinoatrial node of the heart. In most cases, this type of arrhythmia is harmless, requires no special treatment, and does not necessarily restrict the child's daily activities or exercise. However, in cases of pathological causes such as myocarditis or congenital heart disease, participating in strenuous exercise may worsen symptoms and even lead to serious consequences.
For children with physiological sinus arrhythmia, whether they can participate in strenuous exercise should be determined based on individual circumstances. If the child has no other heart problems besides sinus arrhythmia, experiences no activity restrictions in daily life, and has never had symptoms such as syncope or chest pain, they generally can participate in physical activities, including strenuous exercise.
Children with pathological sinus arrhythmia should avoid strenuous exercise. It is advisable to undergo a comprehensive cardiac evaluation first to rule out any underlying heart disease.
Parents are advised to regularly monitor changes in their child's symptoms and, under a doctor's guidance, develop an appropriate exercise plan based on the child's specific health condition.
