Right ventricular systolic pressure 35 mmhg is consistent the 60 60 sign has gained recent attention putatively indicating an acute cause of elevated right ventricular pressures with a pulmonary valve acceleration time 60 ms and a tricuspid regurgitation jet 30 but 60 mmhg. 24 mg of tpa. Of these cardiac and venous measurements the rv lv diameter ratio is the easiest to calculate and should be included in every report of a ct pulmonary angiography examination.
