[Provocative tests and electrophysiological study in athletes]

Area of Science:

• Sports Medicine
• Cardiology
• Diagnostic Testing

Background:

• Pre-participation screening is crucial for athlete safety.
• Identifying cardiac abnormalities in athletes requires appropriate diagnostic tools.
• Different levels of provocative testing exist for various clinical scenarios.

Purpose of the Study:

• To categorize provocative tests used in athlete cardiac evaluation.
• To delineate the roles of different electrophysiological studies in arrhythmias.
• To guide the selection of appropriate diagnostic methods for athletes.

Main Methods:

• Classification of provocative tests into three levels: screening, functional capacity, and advanced diagnostics.
• Review of indications for electrophysiological studies in athletes.
• Comparison of endocavitary versus transesophageal electrophysiological studies.

Main Results:

• First-level tests (e.g., step test) are for general screening.
• Second-level tests (e.g., exercise tests) assess functional capacity or specific indications.
• Third-level tests (e.g., stress echo) are for selected high-risk individuals.
• Endocavitary studies are indicated for ventricular arrhythmias; transesophageal studies are preferred for supraventricular arrhythmias.

Conclusions:

• Provocative tests are tiered based on invasiveness and diagnostic yield.
• The choice of diagnostic test depends on clinical presentation and initial findings.
• Transesophageal electrophysiological study has largely replaced endocavitary study for supraventricular arrhythmias in athletes.
