Components of Beck’s triad [cardiology]

Associated with – acute cardiac tamponade

1. Hypotension with a narrowed pulse pressure
2. Jugular venous distention (JVD)
3. Muffled heart sounds

Hypotension –

pericardial fluid accumulation inside the pericardial sac, which decreases the maximum size of the ventricles

lower EDV (End Diastolic Volume) which reduces stroke volume that causes hypotension

Jugular venous distention (JVD)

Reduced diastolic filling of the right ventricle, due to pressure from the adjacent expanding pericardial sac.

Muffled heart sounds

 Fluid surrounding the heart
