The lung fields are hyperinflated. A prominent pulmonary conus is noted.
The CT scan shows emphysematous changes in both lungs. There is marked dilation of the right main pulmonary artery, pulmonary arterial trunk, and right ventricle.
FEV1 = 50% of predicted value
FEV1/FVC = 0.62
Analysis: suggestive of an obstructive pattern
ECG + Echocardiogram
The ECG shows tall, narrow, peaked P waves in the inferior leads; tall R waves in the right-sided chest leads; and deep S waves in the left-sided chest leads.
The echocardiogram shows right atrial and right ventricular hypertrophy, along with pulmonary hypertension. The left ventricular ejection fraction is normal.
