- Constrictive pericarditis
- Cardiac tamponade
- Right ventricular myocardial infarction (RVMI)
- Restrictive cardiomyopathy
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Beck's triad is a classic set of three signs. The concept tested is which acute cardiac emergency it describes.
Step 2: Beck's triad consists of hypotension (falling blood pressure), muffled or distant heart sounds, and raised jugular venous pressure with distended neck veins.
Step 3: These three together signal acute cardiac tamponade. Fluid rapidly fills the pericardial sac, compresses the heart, limits filling, drops cardiac output and blood pressure, muffles the sounds, and backs up venous pressure. So option B is correct.
Step 4: Why the others are wrong. Constrictive pericarditis is a chronic process with a pericardial knock, Kussmaul sign, and pericardial calcification, not Beck's triad (option A wrong). RVMI causes hypotension and raised JVP but is not defined by Beck's triad (option C wrong). Restrictive cardiomyopathy gives chronic right heart failure features rather than this acute triad (option D wrong).
Step 5: The triad of hypotension, muffled heart sounds, and raised JVP defines tamponade.
Answer: B. Cardiac tamponade.
