Beck Triad in the context of cardiac tamponade includes which characteristic combination?

• A. Hypertension, JVD, muffled heart sounds
• B. Hypotension, edema, muffled heart sounds
• C. Hypotension, JVD, muffled heart sounds
• D. Hypotension, muffled heart sounds, tachycardia

Answer: (C)

Beck triad describes the classic signs of cardiac tamponade: low blood pressure, distended neck veins, and muffled heart sounds. When a large amount of fluid accumulates in the pericardial sac, it raises intrapericardial pressure and prevents the heart from filling properly during diastole. This reduces stroke volume and cardiac output, causing hypotension. The same fluid impedes venous return, so pressure backs up in the venous system and the neck veins become visibly distended (JVD). The external fluid around the heart also muffles the sounds heard with a stethoscope. Tachycardia is common as a compensatory response, but it’s not part of the classic triad, and edema isn’t typically part of this acute picture.
