The treatment of premature heartbeat in children depends on the cause of the premature heartbeat in children. If myocarditis is currently considered to be the cause, it is recommended that the patient take a combination of oral coenzyme Q10, vitamin C, vitamin E and a B-vitamin complex. In addition, oral medications such as Astragalus oral solution can be taken to improve the symptoms, and antiviral medications can also be applied in combination with antiviral treatment. If the condition is caused by ionic disorders, such as hyponatremia or hypokalemia, the ionic disorders should be corrected in combination with the ionic disorders, and only after the ionic disorders are corrected will the condition of premature beats be improved. Other children may have premature contractions caused by a cold, and treatment of the cold is sufficient.
