FINDINGS:
The pacemaker is visualized on the left chest wall ; the pacer leads terminate
 in the right atrium and the apex of the right ventricle.  The heart is mildly
 enlarged.  As noted in the previous study, there is pulmonary vascular
 congestion without overt edema or pleural effusion.  There is linear
 atelectasis of the left lung base.  No consolidations nor pneumothorax seen. 
 A stable compression deformity of the thoracolumbar junction vertebral body is
 also seen.

IMPRESSION:
1. Pacing leads terminate in the right atrium and the apex of the right
 ventricle.
