    INPUT: Dual lead left - sided pacemaker is seen with leads extending to the expected positions of the right ventricle and very proximal right atrium . No focal consolidation is seen . There is slight blunting of the costophrenic angles which may be due to minimal atelectasis versus very trace pleural effusions . No pneumothorax is seen . The cardiac and mediastinal silhouettes are unremarkable .
    OUTPUT:
    
Dual lead left - sided pacemaker is seen with leads extending to the expected positions of the right ventricle and very proximal right atrium . Atrial lead may be slightly proximal in position . Slight blunting of the bilateral costophrenic angles may be due to minimal atelectasis versus trace pleural effusions .
