The significance of early repolarization and incomplete right bundle block in athletes
Introduction:
Sudden death in athletes is a major concern; the predictors and value of prior investigations remain to be
settled. Of the electrocardiographic (ECG) findings in athletes is early repolarization, its incidence and significance is the
subject of this work.
Methods:
The study included hundred persons engaged in competitive sports for duration not less than six months; with
training at least three days per week and at least two hours per day. All were males. Collection of cases started March till
December 2015. Full history especially questioning for syncope, tachycardia or chest pain was obtained as well as family
history of sudden death or coronary disease; examination for BP, any cardiac murmurs or arrhythmia. ECG was done for
all plus echo Doppler in some cases. Early repolarization was accepted present if J point is elevated more than one mm in
LII, III, aVF or in chest leads, raised ST>1mm. RV conduction disturbance was considered present if there is Rsr' or bifid
R. Minor or minimal changes were not counted.
Results:
During the period from 1/1/2015 to 1/10/2016, 100 athletes were screened by ECG, 54 played isotonic sport
while 46 were on isometric sport. Types of sports: 46 isometric (static) (body builders). Isotonic (dynamic) 54 (Bicycling
6, Football 15, Tennis 3, Basketball 16, Volleyball 8, Swimming 4, Boxing 2) . Echo was done in 15, increase in LV size
was found in 5 (Diastolic diameter up to 61mm). Follow up by telephone questionnaire was done for most of the subjects.
10 persons were re-examined after months, no abnormal events were found. 23 had either or both abnormalities. Early
repolarization was found in 19 and Rsr' were present in 9 subjects (5 had both). None was diagnosed as Brugada or
RV dysplasia. Follow up by telephone was up to two years. Of the 23 subjects 2 could not be reached (no answer) and
in 2 the telephone was wrong. No one reported tachyarrhythmia or syncope neither before recruitment in the study
(retrospective) or after follow-up (prospective).
Conclusion:
Early repolarization and RV conduction disturbance did not prove to be hazardous.
