543 Possible Causes for Bifascicular Block, Focal Atrophy of Choroid, Prolonged PR Interval

  • Hemochromatosis

    The spectral domain optical coherence tomography showed retinal pigmentary epithelial atrophy associated with irregularities and focal interruption of the ellipsoid zone.[ncbi.nlm.nih.gov] A thin retina was also observed in the foveolar region associated to a thickened choroid. Full-field electroretinogram showed a decrease of rods and cones responses.[ncbi.nlm.nih.gov]

  • Cardiomyopathy

    Cardiomyopathy is disease in which the heart muscle becomes weakened, stretched, or has another structural problem. It often occurs when the heart cannot pump or function well. Most people with cardiomyopathy have heart failure. There are many types of cardiomyopathy, with different causes. Some of the more[…][medlineplus.gov]

    Amyloidosis refers to a group of diseases resulting from abnormal deposition of amyloids in various tissues. In patients with amyloidosis, symptoms presented are as a result of the abnormality in the function of the particular organs involved. Some of the organs that can be affected include the heart, kidney, liver,[…][symptoma.com]
