  • Ostium Primum Atrial Septal Defect

    When a person is suspected of having an ASD based on the findings of an incomplete right bundle branch block with a rSr' or rSR', the frontal plane QRS should be examined.[en.wikipedia.org] Right ventricle hypertrophy markers or incomplete right bundle branch block may be present.[symptoma.com] In Primum defects left axis deviation is seen in most patients with an axis of -30 degrees and very few patients have right axis deviation.[ipfs.io]
