The Efficacy of Electrocardiograms as a Screening Tool to Detect Cardiac Abnormalities in Young Athletes

• Sudden cardiac death (SCD) among athletes can be attributed to increased cardiovascular demands associated with vigorous exercise.
• The majority of athletes who experience sudden cardiac death are asymptomatic.
• Pre-participation history and physicals, (H&P) help to identify underlying cardiovascular disorders with the potential to increase the risk of SCD in an athlete.
• The efficacy of pre-participation H&Ps to identify underlying cardiac etiology has been debated.
• The purpose of this research is to:
---Determine incidence and cause of SCD among athletes (Table 1).
---Determine the efficacy and evidenced-based criteria for the interpretation of ECGs in athletes.
---Evaluate cost-effectiveness of screening with ECG.
• The findings indicate:
---Incidence of SCD is 1-3/100,000 athletes.
---The addition of ECG to the H&P improves sensitivity to 70% and specificity to 94.1% resulting in early detection of cardiac abnormalities and decreases the incidence of SCD.
---The refined criteria significantly reduces false-positive rates for ECG interpretation (p<0.0001).
---The ECG saves an additional 2.1 life years/1000 athletes screened at a cost of $88.
