This PA chest X ray shows pulmonary venous congestion. The congestion is demonstrated by enlarged 
 hilar shadows  with increased pulmonary venous markings, especially in the 
 upper lobes, that is, cephalization. The dilated smaller vessels can be followed all the way to the periphery. The heart size is large, with a 
 cardiothoracic ratio greater than fifty percent. There is a prominent left ventricle. Note the 
 monitoring electrodes can be seen on the X ray.
