Abstract Background: Electrocardiogram (ECG) testing in pre-participation screening (PPS) remains controversial due to its cost, resource dependency, and the potential for inaccurate interpretations. At most centres, ECGs are conducted internally by providers trained in athletic ECG interpretation. Outsourcing ECG requisitions to an athlete's primary care network (PCN) may reduce institutional demands. This study compared PCN-conducted athletic ECG interpretation to expert sports cardiology interpretation.
Methods: This was a retrospective, single-centre chart-review study of all athletes who underwent cardiovascular PPS between 2017 and 2021. All athletes submitted an ECG with their screening package, which was conducted and interpreted within their PCN. All ECGs were reinterpreted by a sports cardiologist using the International Criteria (IC) for electrocardiographic interpretation in athletes. Overall, positive, and negative percent agreement were used to compare PCN-conducted ECG interpretation with IC interpretation.
Results: A total of 740 athletes submitted a screening package with a valid ECG (mean age: 18.5 years, 39.6% female). PCN-conducted ECGs were interpreted by 181 unique physicians. Among 41 (5.5%) PCN-conducted ECGs that were initially interpreted as abnormal, only 5 (0.7%) were classified as abnormal according to the IC. All PCN-conducted ECGs reported as normal were also classified as normal according to the IC. The overall agreement between PCN-conducted and IC ECG interpretation was 95.1% (positive percent agreement: 100%, negative percent agreement: 95.1%).
Conclusions: Normal PCN-conducted athletic ECGs are interpreted with high agreement to the IC. Majority of PCN-conducted ECGs interpreted as abnormal are indeed normal as per the IC. These findings suggest that a PPS workflow model that outsources ECG requisitions to a PCN may be a reliable approach to PPS, all while reducing screening-related institutional costs and resource requirements.
