Question: Should I worry about early repolarization?

Early repolarization of the QRS complex on the surface ECG has long been considered to be a benign finding, but is now recognized as being associated with malignant ventricular arrhythmias and sudden death.Early repolarization of the QRS complex

Is early repolarization bad?

Early repolarization, ST-segment elevation in the absence of conduction abnormalities, or chest pain has been considered as a normal state for more than half a century. Because this ECG pattern predominates among young and fit individuals with slow heart rates, it has been generally viewed as a marker of good health.

Is early repolarization pattern normal?

Because early repolarization is common and studies suggest that it is associated with an increased risk of sudden cardiac death, it is important that health care providers are able to recognize the ECG pattern.

What causes early repolarization?

Early repolarization is more frequently found in genetic relatives of patients with a history of arrhythmic sudden cardiac death, what suggests pro-arrhythmic genetic mutations and in several recent studies, early repolarization syndrome has been described as a kind of heritable disease.

What does early repolarization look like on 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 ...

What is the meaning of early repolarization changes?

Early repolarization (ER), also recognized as “J-waves” or “J-point elevation” is an electrocardiographic abnormality consistent with elevation of the junction between the end of the QRS complex and the beginning of the ST segment in 2 contiguous leads[9,10].

What happens early repolarization?

Early repolarization (ER), also recognized as “J-waves” or “J-point elevation” is an electrocardiographic abnormality consistent with elevation of the junction between the end of the QRS complex and the beginning of the ST segment in 2 contiguous leads[9,10].

When does repolarization occur in the heart?

Phase 0 is the phase of depolarization; Phase 1 through 3 is the phases during which repolarization occurs; Phase 4 is the resting phase with no spontaneous depolarization. During phase zero, the phase of rapid depolarization, voltage-gated Na+ channels open, resulting in a rapid influx of Na+ ions.

What does repolarization mean in the heart?

Repolarization is the return of the ions to their previous resting state, which corresponds with relaxation of the myocardial muscle. 8. Depolarization and repolarization are electrical activities which cause muscular activity.
