Viral myocarditis can be cured in about 3 weeks with appropriate treatment. If combined with arrhythmias, antiarrhythmic medication is usually continued for more than 3 months. Patients with fulminant myocarditis may soon develop severe arrhythmias, heart failure, shock, and death, and a small number of patients may develop dilated cardiomyopathy with recurrent heart failure and arrhythmias, which may be more prolonged over time. Viral myocarditis should be detected early, diagnosed early, treated early, get more rest, and have a reasonable diet.
