| Introduction Early repolarization (ERP) is a common electrocardiographic finding. Its potential to cause cardiac arrhythmias has been hypothesized from experimental studies, but it is not known whether there is a clinical association with sudden cardiac arrest. Methods 122 subjects (100% males; mean age: 13.5 +/- 2.7 years) were included from a local youth soccer team in Belgium. All subjects underwent physical examination and a 12-lead ECG was taken.The main objective of the study was to evaluate early repolarization patterns and to determine its prevalence. Results Of the 122 included subjects, 1 subject with Coumel tachycardia was excluded. The overall prevalence of ERP in our study population was 36%, with 9.1% in the inferior leads, 8.2% in the lateral leads and 18.2% both leads. A family history of sudden cardiac death (SCD) was not higher in the group of ERP (N =3; 6.8%) compared to the non-ERP group (N =4; 5.2%) (P=0.713). Interestingly, incomplete right bundle-branch block (IRBBB) was significantly lower among all subjects with ERP (N =15; 34.1%), compared to those without ERP (N= 49; 63%) (P < 0.002). Conclusion ERP is a common finding in young teen athletes. In this population global ERP (both inferior and lateral) is more common than isolated inferior or lateral ERR Young age might be a contributing factor in causing a more diffuse repolarization abnormality. |
