Early repolarization

Background

• Mostly seen in healthy patients <50, less likely >50, unlikely >70
• Shows diffuse ST elevation similar to pericarditis and STEMI
• Underlying pathophysiology poorly understood, however, it is a normally a benign process

ECG Findings

• Widespread concave ST elevation more prominent in V2-V5, elevation of ≥0.1 mV in two adjacent leads
• Notching or slurring of the J point
• ST elevation is <25% of the T wave height in V6
• No reciprocal ecg changes or ST depressions (unless in aVR)
• ST changes stable over time

Early Repolarization Syndrome

• Early Repolarization is a benign finding with asymptomatic patients
• Early Repolarization syndrome applies to patients with early repolarization along with symptomatic arrhythmias such as Ventricular Fibrillation
  • This is a diagnosis of exclusion

Differential Diagnosis

• STEMI
• Pericarditis
