Sudden cardiac death in athletes is often due to undiagnosed heart conditions. Evolving electrocardiogram (ECG) interpretation criteria help differentiate normal athletic adaptations from disease, reducing misdiagnosis and costs.

Area of Science:

Cardiology
Sports Medicine
Medical Diagnostics

Background:

Sudden cardiac death (SCD) is a leading cause of mortality in athletes, frequently linked to undiagnosed cardiovascular diseases.
Athletes exhibit ECG changes due to physiological adaptations from exercise, which can mimic pathological patterns.
Accurate ECG interpretation is crucial to distinguish normal physiological changes from underlying cardiac pathology, preventing misdiagnosis and unnecessary interventions.

Purpose of the Study:

To review the historical evolution of electrocardiogram (ECG) interpretation guidelines for athletes.
To highlight the advancements in differentiating physiological ECG changes from pathological findings in athletes.
To discuss the impact of updated international recommendations on athlete screening and cost-effectiveness.

Keywords:

Main Methods:

Literature review of consensus documents and recommendations on ECG interpretation in athletes.
Analysis of the progression of ECG criteria from 2005 to 2017.
Examination of the impact of recent international recommendations on diagnostic accuracy and screening costs.

Main Results:

ECG interpretation criteria for athletes have undergone significant evolution over the past 12 years.
Recent international recommendations (2017) have substantially reduced false positives in ECG screening.
Updated criteria have led to decreased screening-associated costs and fewer unnecessary investigations or disqualifications.

Conclusions:

The evolution of ECG interpretation guidelines has improved the accuracy of screening for cardiovascular disease in athletes.
Current international recommendations offer a more refined approach to differentiating physiological adaptations from pathology.
Future directions in ECG interpretation aim to further enhance diagnostic precision and optimize athlete health management.
