Early repolarization syndrome
Early repolarization syndrome – ERS is commonly seen in
- athletes,
- cocaine users
- hypertrophic obstructive cardiomyopathy
- defects and/or hypertrophy of interventricular septal defects[
- Prevalence of ERS varies between 3% and 24% in the general population, depending on the population studied and methods used for ECG interpretation.
- Common in population – Young individuals, especially those predisposed to vagotonia, males, African Americans, and athletes are subpopulations known to have a higher prevalence of ERS
cardiac arrhythmias
Tikkanen et al demonstrated that the location (inferior vs lateral leads) as well as J-point elevation of > 0.2 mV are linked to a significant risk of death from cardiac arrhythmias (adjusted relative risk, 2.98; 95%CI: 1.85-4.92; P < 0.001).
Early repolarization – called J-point elevation
- Type of ST-segment elevation is present in healthy individuals – early repolarization, called J-point elevation.
- It is distinguished by the fact that the T wave does not merge with the ST segment and remains an independent wave.
