Early repolarization syndrome is a clinical syndrome characterized by the presence of characteristic early repolarization waves on the electrocardiogram with concomitant malignant arrhythmias.
Early repolarization syndrome is a clinical syndrome diagnosed by electrocardiogram that presents with characteristic early repolarization waves, also known as J waves, and concomitant malignant arrhythmias.
Its main causes include autonomic dysfunction, cardiac conduction abnormalities, genetic mutations, or familial inheritance. Typical symptoms are decreased heart rate, blood pressure, cold extremities, dizziness, headache, chest tightness, panic, shortness of breath, etc. It is often confused with angina pectoris and myocardial infarction.
Most of the early repolarization syndrome belongs to benign lesions, the general prognosis is better, but if ventricular fibrillation occurs, the prognosis is worse, it can be life-threatening, sudden death is more likely, so it is recommended that you still need to actively seek medical attention, improve the examination, and cooperate with the doctor for treatment if necessary.
