Early repolarization syndrome, also known as early repolarization syndrome, is a type of cardiac repolarization abnormality, which is a physiological ECG variation. In most cases, early repolarization syndrome is a benign clinical process, but due to the similarity of its ECG alteration mechanism with pathological Brugadar syndrome, idiopathic ventricular fibrillation and acute myocardial ischemia, as well as its non-specific clinical manifestations, it is very easy to be confused with other organic The clinical manifestations are non-specific and can be easily confused with other organic heart diseases, which should be adequately diagnosed differently. Early repolarization syndrome is a benign variant and generally does not require special treatment. If combined with neurocirculatory abnormalities, symptomatic treatment can be given, analgesics can be given for chest pain, nitroglycerin preparations can be given in severe cases, and antiarrhythmic drugs can be given for arrhythmias.
