Which test helps rule out a pericardial effusion in suspected pericarditis?

• A. ECHOCARDIOGRAPHY
• B. TROPN TREND
• C. ECG
• D. CHEST X-RAY

Answer: (A)

Detecting a pericardial effusion requires imaging that directly visualizes the pericardial space and can assess its hemodynamic impact. Echocardiography uses ultrasound to rapidly show whether fluid surrounds the heart, estimate the effusion’s size, and identify signs of tamponade such as chamber compression or abnormal variation in filling. Because it can detect even small amounts of fluid at the bedside and evaluate its effect on heart function, it’s the most reliable test to rule out an effusion in suspected pericarditis. Troponin trend helps distinguish myocardial injury but doesn’t visualize fluid around the heart. ECG changes are common in pericarditis but don’t reliably indicate whether an effusion is present. Chest X-ray may miss small effusions and only suggests large ones, so it cannot safely rule out an effusion.
