Objective:
To explore the differential diagnosis of early repolarization syndrome (ERS) in patients with ST-segment elevation and its clinical significance.
Methods:
Five patients with ESR were clinically observed and followed up after discharge from hospital.
Results:
All the patients complained of chest distress or chest pain, accompanied by ST-segment elevation in the precordial electrocardiogram leads.
Conclusion:
ESR is often misdiagnosed as acute myocardial infarction, acute coronary syndrome, Brugada syndrome or other diseases that may involve elevated ST-segment, and careful examination of the ECGs, echocardiogram, troponin I and the patients' history of heart diseases may help differentiate ESR from these diseases.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
