title: Low-pressure cardiac tamponade.
abstract: An elderly man developed cardiac tamponade from a tuberculous pericardial effusion but without such typical manifestations as pulsus paradoxus and jugular-vein distension. This case illustrates the difficulties in clinical recognition of low-pressure cardiac tamponade, which can develop in the presence of dehydration and hypovolemia. The hemodynamic factors that account for this phenomenon are discussed.
