Beck’s triad

Beck triad is seen in cardiac tamponade. The three clinical signs that comprise the Beck triad are

  • low blood pressure (weak pulse or narrow pulse pressure)
  • muffled heart sounds
  • raised jugular venous pressure, seen as distended neck veins

Although the full triad is present only in a minority of cases of acute cardiac tamponade, presence of the triad is considered pathognomonic for the condition.
