How can you tell the difference between ST elevation and early repolarization?
Table of Contents
In other words, the T wave in early repolarization is usually 4 times the amplitude of the ST elevation. Another way to describe this would be that the ST elevation is less than 25% of the T wave amplitude in early repolarization. The ST elevation in early repolarization resolves when the person exercises.
How is J point elevation different from ST elevation?
ST segment / T wave morphology

- There is elevation of the J point.
- The T wave is peaked and slightly asymmetrical.
- The ST segment and the ascending limb of the T wave form an upward concavity.
- The descending limb of the T wave is straighter and slightly steeper than the ascending limb.
Should I be worried about early repolarization?
No. The early repolarization pattern on electrocardiography (ECG) in asymptomatic patients is nearly always a benign incidental finding. However, in a patient with a history of idiopathic ventricular fibrillation or a family history of sudden cardiac death, the finding warrants further evaluation.
What does early repolarization on ECG mean?
The presence of early repolarization (ER) pattern in the 12-lead ECG, defined as elevation of the QRS-ST junction (J point) often associated with a late QRS slurring or notching (J wave), is a common finding in the general population, particularly in the inferior and precordial lateral leads.

What is early repolarization ECG?
Early repolarization pattern (ERP) is a common ECG variant, characterized by J point elevation manifested either as terminal QRS slurring (the transition from the QRS segment to the ST segment) or notching (a positive deflection inscribed on terminal QRS complex) associated with concave upward ST-segment elevation and …
Can early repolarization cause ST elevation?
Early Repolarisation syndrome have a wide differential including Brugada Syndrome, short and long QT syndromes as well as other conditions causing ST segment elevation (ST segment elevation MI, acute pericarditis and idiopathic VF).
What does early repolarization mean in ECG?
Is early repolarization fatal?
Early repolarization syndrome (ERS), demonstrated as J-point elevation on an electrocardiograph, was formerly thought to be a benign entity, but the recent studies have demonstrated that it can be linked to a considerable risk of life – threatening arrhythmias and sudden cardiac death (SCD).
