Epicardial Leads
CXR shows a biventricular pacemaker with two wires in the atrial appendage (green arrows) and the second in the apex of the right ventricle (white arrow).
In addition, there is an epicardial lead arising from the battery pack (red arrow). Temporary epicardial leads are frequently placed during cardiac surgery and are then removed in the post op period. In this instance they were probably placed due to failed pacing from the biventricular intracardiac leads
