FINDINGS:
A left-sided dual-chamber pacemaker device is noted with leads terminating in
 the right atrium and right ventricle.  The cardiac, mediastinal and hilar
 contours are normal.  The pulmonary vascularity is normal.  Curvilinear
 opacity within the left lung base on the frontal view likely reflects
 atelectasis or scarring.  No focal consolidation, pleural effusion or
 pneumothorax is present.  There are no acute osseous abnormalities.

IMPRESSION:
No acute cardiopulmonary process.
