For patients with mild myocarditis, treatment measures are as follows: First, general treatment, bed rest, avoiding emotional stress and mood swings. Second, the patient should be monitored for blood pressure, heart rate, oxygen saturation, pulse and other vital signs. The patient should also complete relevant tests, such as an 18-lead electrocardiogram and myocardial enzymology, and should limit physical activity for at least six months. Thirdly, medication should be given to improve the myocardial energy metabolism, such as sodium creatine phosphate, coenzyme complex, coenzyme Q10, etc. Fourth, supplementation of water-soluble vitamins, such as injectable vitamin C. Fifth, if the patient has a viral infection, antiviral drugs can be given, such as ribavirin, ganciclovir, cytarabine and so on. If the patient has arrhythmias, beta-blockers or amiodarone can be applied symptomatically to regulate the heart rate. Treatment of mild myocarditis usually provides relief.
