Beck's triad consists of which three findings?

Beck's triad reflects the hemodynamic effects of cardiac tamponade, where fluid or blood in the pericardial sac restricts the heart’s filling. The first finding, low blood pressure, occurs because reduced ventricular filling leads to a drop in stroke volume and cardiac output. The muffled heart sounds come from the presence of fluid around the heart that dampens the sound transmission during auscultation. The distended neck veins arise because impaired right atrial filling and back pressure from the blocked venous return cause venous blood to back up into the jugular veins. When these three signs appear together, they strongly point to tamponade, a life-threatening condition that requires rapid evaluation and definitive care. Other options describe signs that are not specific to tamponade. Fever with hypotension and tachycardia suggests infection or another shock state. Chest pain with shortness of breath and hypoxia is nonspecific and could indicate many cardiopulmonary problems. Jaundice with edema and hypotension points more toward liver disease or other systemic issues rather than cardiac tamponade.
