Whether second-degree AV block in children can heal on its own is analyzed on a case-by-case basis. Second-degree AV block is categorized into type I and type II.
Second-degree type I atrioventricular block is mostly functional damage, usually caused by some reversible or transient causes, such as rheumatic myocarditis, acute infections, hypoxia and hyperkalemia, taking digitalis and so on, which generally cause few clinical symptoms, and can be cured by treating the primary disease or stopping the drug, and if the cause of symptomatic bradycardia needs specialized treatment, generally with a better prognosis.
2. Second-degree type II AV block is mostly caused by organic damage, commonly seen in coronary artery disease, cardiomyopathy, or congenital or primary degenerative changes in the conduction system, and often has obvious clinical symptoms such as dizziness, palpitations, and even episodes of A.V.S. Syndrome, which usually requires medication and the implantation of a pacemaker, and generally has a poorer prognosis.
If children suffer from second-degree AV block, they should go to the hospital as soon as possible for treatment, to clarify the cause of the disease and the type of the disease, and follow the doctor’s instructions to actively carry out the treatment, so as not to aggravate the condition.
