Beck Triad EXCEPT

• A. Hypotension
• B. JVD
• C. Muffled heart sounds
• D. Pulsus paradoxus

Answer: (D)

Beck's triad describes the classic signs of cardiac tamponade: low blood pressure from reduced cardiac output, distended neck veins from impaired venous return, and muffled heart sounds because the pericardial fluid dampens sound transmission. Pulsus paradoxus, while it can be seen in tamponade, is not one of the defining trio. It’s an exaggerated drop in systolic blood pressure during inspiration due to ventricular interdependence in the setting of pericardial pressure, but it’s not part of the traditional triad.

So the sign that isn’t part of Beck’s triad is pulsus paradoxus. In a patient with tamponade, you’d expect hypotension, JVD, and muffled heart sounds; pulsus paradoxus may be present as an additional finding but is not part of the triad itself.
