Brugada pattern
Pronunciation: broo-GAH-da
Distinctive ECG abnormality that may indicate increased risk of sudden cardiac death.
Full Definition
The Brugada pattern refers to characteristic electrocardiographic findings in the right precordial leads, featuring coved ST-segment elevation followed by negative T-waves, which may indicate Brugada syndrome. In sports cardiology, identifying this pattern is critical as it can be associated with increased risk of ventricular arrhythmias and sudden cardiac death, particularly during exercise or periods of increased sympathetic activity. The pattern may be concealed at rest and revealed only during exercise testing, fever, or pharmacological challenge. Athletes with confirmed Brugada pattern typically require activity restriction and may need implantable cardioverter-defibrillator therapy.
Usage
Usage note: Capitalize as proper noun; specify type (1, 2, or 3) when known.
