Key result
ECG abnormalities predict adverse outcomes in pediatric dilated cardiomyopathy.
Why the study?
Despite increasing studies of electrocardiography in DCM, a comprehensive summary of the prognostic value of ECG markers in children with DCM is lacking.
Do electrocardiographic markers predict adverse outcomes in children with dilated cardiomyopathy?

ECG markers may support risk stratification in pediatric dilated cardiomyopathy; leaves open need for prospective validation before clinical adoption.
Dilated cardiomyopathy (DCM) refers to a heterogeneous group of cardiomyopathies characterized by ventricular dilatation and myocardial systolic dysfunction, which can lead to serious consequences such as malign arrhythmia, sudden death, heart failure, and thromboembolism. With its economical, non-invasive, simple and reproducible advantages, electrocardiogram (ECG) has become an important indicator for assessing the prognosis of cardiovascular diseases. In recent years, more and more studies of electrocardiography on DCM have been carried out, but there is still a lack of a comprehensive summary of its prognostic value. This article reviews the prognostic value of electrocardiographic markers in children with DCM.

Wang et al. (2022) conducted a review in Dilated cardiomyopathy. Electrocardiographic markers was evaluated. Electrocardiographic markers such as P wave, QRS wave, QT interval, ST segment, and T wave abnormalities have positive predictive value for adverse prognosis in children with dilated cardiomyopathy.
