  • Coronary Atherosclerosis

    INTRODUCTION: Ischemic heart disease (IHD) related to atherosclerotic coronary artery disease (CAD) is one of the most prevalent causes of death in Europe. Postmortem evaluation of IHD remains a challenge because of possible non-specific autopsy finding in some autopsy cases, especially in early myocardial ischemia.[…][ncbi.nlm.nih.gov]

  • 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] When you suspect a patient has an ASD based on the findings of an incomplete Right Bundle Branch Block with a rSr' or rSR' the next thing you should do is examine the frontal[ipfs.io]

  • Posterior Myocardial Infarction

    Also, both patients had complete right bundle-branch block (RBBB) [old in patient 1, new in patient 2], the pattern of which was altered due to the associated PMI.[ncbi.nlm.nih.gov] We present here a patient with the unusual combination of a newly developed right bundle branch block (RBBB) and an acute posterior myocardial infarction (MI).[ncbi.nlm.nih.gov] bundle branch block .[wikidoc.org]
