Status of chest X-ray in diagnosing right ventricular infarction

Right ventricular enlargement on left anterior oblique view at 60 degrees had low sensitivity (58.8%) but very high specificity (100 %) for diagnosing right ventricular infarction. Right ventricular and right atrial enlargement on other views had very low sensitivity (16.7-26.7%) but high specificity (80-90%). Thus chest X-ray in left anterior oblique view at 60% is useful in detecting right ventricular infarction when clinical examination and electrocardiogram are inconclusive.
