The ECG examination just after running can usually make the simple early repolarization wave disappear, while for the early repolarization wave complicated with malignant arrhythmia, it usually can’t disappear. Usually, early repolarization wave may be caused by vegetative nerve function disorder, abnormal conduction of cardiac electrophysiology, gene mutation, family heredity and other factors; if it is only simple early repolarization wave, and there is no other discomforts, elevating the heart rate after running can usually make the early repolarization wave disappeared. If the early repolarization wave is accompanied by electrical storm or malignant arrhythmia, such as ventricular fibrillation, atrial fibrillation and other discomforts, usually the early repolarization wave does not disappear after running, and can be treated with drugs such as isoprenaline, quinidine, etc., and buried cardioverter-defibrillator or radiofrequency ablation if necessary. When the above symptoms appear, it is recommended to go to the hospital in time for early standardized treatment.
