In clinical practice, the most common type of myocarditis is viral myocarditis. Due to a decrease in the body's resistance, the virus invades and damages the myocardium, causing localized and diffuse inflammatory damage to the heart muscle, which poses significant harm to the body. The early clinical symptoms of viral myocarditis often manifest primarily as respiratory and gastrointestinal symptoms, accompanied by palpitations and shortness of breath, necessitating the use of electrocardiograms and myocardial enzyme spectrum tests. Early detection, diagnosis, and treatment of viral myocarditis play a crucial role in the prognosis.
