The electrocardiogram in the highly trained athlete.

Area of Science:

• Cardiology
• Sports Medicine
• Diagnostic Electrocardiography

Background:

• Athletes may present with congenital or acquired structural heart disease.
• Electrocardiogram (ECG) abnormalities can indicate underlying cardiac conditions in athletes.
• Normal ECGs do not always exclude the presence of structural heart disease in athletes.

Purpose of the Study:

• To explore the diagnostic challenges of electrocardiogram interpretation in athletes.
• To differentiate between physiological adaptations and pathological conditions in athletes' hearts.
• To highlight the limitations of electrocardiogram in diagnosing structural heart disease in athletic populations.

Main Methods:

• Review of existing literature on electrocardiogram findings in athletes.
• Analysis of case studies involving athletes with and without structural heart disease.
• Comparison of electrocardiogram patterns in athletes with normal hearts versus those with cardiac pathology.

Main Results:

• Abnormal ECGs can reveal structural heart disease in athletes.
• Structural heart disease may exist in athletes even with a normal ECG.
• ECG changes in athletes can mimic cardiac disease, complicating diagnosis.
• Distinguishing adaptive from pathologic hypertrophy solely on ECG can be challenging.

Conclusions:

• Electrocardiogram is a valuable but not definitive tool for diagnosing heart disease in athletes.
• A comprehensive evaluation beyond the ECG is often necessary for accurate diagnosis.
• Further research is needed to refine diagnostic criteria for athletes' cardiac health.
