Electrocardiogram interpretation in college athletes: Local institution versus sports cardiology center interpretation.

Abstract:

BACKGROUND:Electrocardiogram (ECG) screening in athletes enhances the detection of conditions associated with sudden cardiac death (SCD), but concerns remain for false positive results when conducted outside of specialized centers. This study compared ECG interpretation in college athletes between local physicians and a sports cardiology center (SCC). METHODS:Screening ECGs in athletes from eight Pacific-12 Conference institutions performed between 2010 and 2016 were included. Local interpretation was compared to SCC interpretation using both the Seattle Criteria (SCC-SC) and the International Criteria (SCC-IC). RESULTS:A total of 2445 athlete ECGs (mean age 18.5 years; 57.1% male; 63.2% Caucasian and 15.3% African American) were reviewed. The proportion of ECGs classified as abnormal was similar between local and SCC-SC interpretation (3.5% vs. 3.4%, respectively; p = .94), but was lower by SCC-IC interpretation (1.5%, p < .001). ECG abnormalities interpreted as normal by local physicians but as abnormal by SCC-SC (n = 33) and SCC-IC (n = 16) standards included: pathological Q waves (n = 15 SCC-SC; n = 3 SCC-IC), T-wave inversions (n = 8 both), and ST-depressions (n = 3 both). There was a 97.5% ECG interpretation agreement and substantial interobserver reliability (k = 0.611, p < .001) between local and SCC-SC interpretation in athletes screened starting one year after publication of the Seattle Criteria (n = 1388). Both local and SCC physicians correctly identified six abnormal ECGs associated with conditions at risk of SCD. CONCLUSIONS:ECG interpretation by local physicians at college universities had similar accuracy compared to a specialized SCC with a low overall abnormal rate, similar sensitivity, and substantial interobserver reliability. Uniform application of current ECG interpretation standards is recommended to further improve accuracy.
