Hemopericardium, anticoagulation, and an endocardial pacemaker. A case report with description of new auscultatory and radiographic signs.

A case of organizing hemopericardium and cardiac tamponade in a patient with a permanent endocardial pacemaker who was maintained on anticoagulation is presented. The hemopericardium is concluded as solely due to the anticoagulation. A new auscultatory finding attributable to an endocardial pacemaker and a helpful radiographic sign of pericardial effusion in patients with these pacemakers is described.
