NREMT Paramedic Practice

Which clinical findings are part of Beck's Triad?

1. Elevated JVD, hypertension, tachycardia

2. Muffled heart sounds, hypotension, elevated central venous pressure

3. Cool extremities, chest pain, diaphoresis

4. Bradycardia, cyanosis, decreased temperature

The correct answer is: Muffled heart sounds, hypotension, elevated central venous pressure

Beck's Triad is a clinical syndrome that indicates cardiac tamponade, a condition where fluid accumulates in the pericardial sac and exerts pressure on the heart, hindering its ability to pump effectively. The triad consists of three specific findings: muffled heart sounds, hypotension, and elevated central venous pressure (CVP). Muffled heart sounds occur because the fluid surrounding the heart dampens the sound of the heartbeats, making them less audible during auscultation. Hypotension results from the decreased stroke volume and cardiac output due to the pressure on the heart, leading to inadequate perfusion to the body's organs and tissues. Elevated central venous pressure is indicative of increased pressure in the venous system, often seen due to impaired filling of the heart chambers caused by the surrounding fluid. These three findings together provide essential clues for healthcare providers in diagnosing cardiac tamponade and guiding appropriate interventions. Understanding Beck's Triad is vital for recognizing and managing this potentially life-threatening emergency effectively.
