Study sparks debate over benefit of ECG screening in young athletes
EXPERT opinion remains divided over the advantages of ECG screening in young athletes. While some US experts advocate following the Italian model of annual screening, use of ECGs did produce a high rate of false positives in a recent study. Among the 510 US athletes studied, 83 ECGs were abnormal but only 10 athletes were shown to have heart abnormalities, leading to unnecessary testing and exclusion from sports. Five of these athletes had abnormalities identified by history and physical examination alone. Tom Briffa (PhD), associate professor in cardiovascular epidem-iology at the University of WA, said at least ...
Long QT affects more people than estimated
THE prevalence of the genetic arrhythmogenic disorder, long QT syndrome (LQTS), may be significantly higher than previously thought. Italian researchers who conducted the first large-scale population-based study of its prevalence say it may be present in as many as one in every 2500 people, far more than previous estimates. They conducted ECG-guided molecular screens in 44,596 infants aged 15-25 days old. In total, 17 of 43,000 white infants were affected by LQTS. Approximately 515 family members of genotype-positive infants were found to carry disease-causing mutations. “ECG-guided molecular screening can identify most infants affected by LQTS ...
