Beck's triad of cardiac tamponade includes all, except?: (A) Hypotension, (B) Increased JVP, (C) Muffled Hea sounds, (D) Tachycardia
Answer is D. Beck's triad: Hypotension Soft or absent hea sounds Jugular venous distention with a prominent x descent but an absent y descent. There are both limitation of ventricular filling and reduction of cardiac output. There may be reduction in amplitude of the QRS complexes, and electrical alternans of the P, QRS, or T waves should raise the suspicion of cardiac tamponade.
