Early repolarization
From WikEM
Contents
Background
- Mostly seen in healthy patients <50, less likely >50, unlikely >70
- Typical patient is male, black, athlete
- 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
