Early prediction of its occurrence and timely intervention are important. Among the various indicators for predicting atrial fibrillation, electrocardiogram and related parameters have been proven to have significant predictive value in recent years. This article elaborates and summarizes the predictive value of electrocardiogram parameters in atrial fibrillation in recent years.
