Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Slightly rotated positioning . There are low inspiratory volumes . A left - sided pacemaker type device is present , with lead tips over the right atrium and right ventricle . Perhaps due to positioning or technique , continuity of the right ventricular lead can not be confirmed on these images . There is probable cardiomegaly , including prominence of the right heart . Mild unfolding of the aorta . Mild prominence of the vascular markings is noted , though this is likely accentuated by low lung volumes . There is minimal bibasilar atelectasis . No definite consolidation . No gross effusion . No pneumo thorax detected .
    OUTPUT:
    
Low inspiratory volumes and bibasilar atelectasis . Cardiomegaly . Pacemaker type device present . Please note that continuity of the right ventricular lead can not be traced on these images , though this could be due to technical factors and positioning . If clinically indicated , a repeat AP view centered lower and with increased exposure could help for further assessment . No overt CHF or frank consolidation . An early focus of aspiration or infectious infiltrate could be obscured due to low lung volumes .
