Abstract:
Acute myocarditis is defined as an inflammatory disease primarily limited to the myocardium and is a critical ill condition with diverse clinical manifestations. Due to the lack of specific clinical manifestations，early diagnosis of myocarditis is challenging. The inability to diagnose it early is one of the important causes of death in patients with myocarditis. Electrocardiogram has the characteristics of being fast，timely，and convenient，and has a certain effect on the early diagnosis，condition monitoring，and evaluation of treatment effectiveness of myocarditis. It is widely used as a preliminary screening tool for myocarditis. Due to myocardial cell edema，metabolic disorders，necrosis，and fibrosis，patients with myocarditis exhibit a variety of electrocardiogram manifestations，including QRS low voltage，pathological Q waves，QRS complex widening，ST-T changes，and arrhythmias. In addition，some electrocardiogram changes are independent predictors of poor prognosis in patients with myocarditis，which can be used to guide treatment and determine treatment time and follow-up frequency. This article elaborated on the electrocardiogram characteristics，formation mechanism，and prognostic role of patients with myocarditis.
