Suggests isolated QTc prolongation in asymptomatic athletes may not mandate immediate disqualification; leaves open the.
Cross-Sectional (n=2,000)
In elite athletes, a prolonged QTc is rare (0.4%), and a QTc >500 ms is highly suggestive of true long QT syndrome, whereas a QTc <500 ms without symptoms or family history is unlikely to represent LQTS.
Basavarajaiah et al. (2007) conducted a cross-sectional in Prolonged QTc interval (n=2,000). Prolonged QTc interval vs. Normal QTc interval was evaluated on Prevalence of prolonged QTc interval. A prolonged QTc interval was present in 0.4% of elite athletes, with values >500 ms highly suggestive of long QT syndrome and values <500 ms unlikely to represent the disease.
