Hemopericardium, Anticoagulation, and an Endocardial Pacemaker

Abstract
A case of organizing hemopericardium and cardiac tamponade in a patient with a permanent endocardial pacemaker who was maintained on anticoagulation was presented. The hemopericardium was 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 was described.
