Early repolarization is mostly considered to be early repolarization syndrome, which may be related to sympathetic excitability, genetics and other factors, most of them are asymptomatic, and some patients may also have palpitations, dizziness and other symptoms, and the examination shows J-points, ST-segment elevation and so on, which generally do not need to be treated, but some patients need to take drug treatment. Early repolarization syndrome is a physiological ECG variant. It has been shown that it may be related to factors such as increased sympathetic excitability and genetics. Since early repolarization syndrome is a benign clinical process and is not caused by organic disease, in most cases patients do not have any symptoms. However, there are some patients who have palpitations, dizziness, chest tightness, chest pain and other manifestations of autonomic dysfunction. Secondly, the patient’s ECG has changes such as J-point, ST-segment elevation, and T-wave elevation. Usually, early repolarization syndrome requires no treatment. For those with chest pain, pain relievers such as ibuprofen and acetaminophen are prescribed. In case of arrhythmia, sodium channel blockers such as procainamide and quinidine, beta-blockers such as atenolol and metoprolol, and calcium channel blockers such as verapamil and diltiazem are prescribed, and the prognosis is generally good. In summary, it is recommended that patients with early repolarization syndrome should strengthen their daily life management, follow up on time, and cooperate with their doctors for standardized treatment if necessary.
