Our study constructed a simple screening model for DCM entirely was based on ECG parameters and identified V1SA, V3SA, aVFRA, V6RA, and PR interval as independent screening indicators. ECG, as the first step of the diagnosis of cardiovascular disease, still plays a powerful role in the evaluation of DCM patients. It’s estimated that 80% of patients with DCM have an abnormal ECG.Historically, many electro cardiologists and clinicians have continuously explored the relationship between ECG and cardiomyopathy. As early as 40 years ago, Goldberger proposed to predict ECG triad in patients with congestive heart failure, including high precordial QRS wave voltage, relatively low limb lead voltage, and poor precordial R wave progression.Our model is applicable to a wide range of potential DCM patients, especially for first-degree relatives of DCM patients. Familial DCM accounts for approximately 20% - 50% of DCM,In recent years, the analysis of predictors of ECG for the diagnosis and risk assessment of DCM has been also emerging in endlessly. For example, anterolateral lead T-wave inversion may be a predictor of heart transplantation in patients with DCM, and V2 lead S-wave, III lead R-wave, and anterolateral T-wave inversion may be a predictor of sudden cardiac death in patients with DCM.
