868 Possible Causes for Conduction Disorder of the Heart, 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

    It is recognized that arrhythmias and conduction disease may be primary myocardial disorders.[circ.ahajournals.org] Specific Cardiomyopathies The term specific cardiomyopathies is now used to describe heart muscle diseases that are associated with specific cardiac or systemic disorders.[circ.ahajournals.org]

  • AV Block Mobitz I

    PR interval gradually prolongs and the 5th beat from the left is not conducted. The cycle restarts and PR interval gradually prolongs again.

  • Second Degree Atrioventricular Block

    This case demonstrates the need for caution and interval cardiac testing when adding LCM to other AEDs known to prolong the PR interval.[ncbi.nlm.nih.gov] I45.9 ICD-10-CM Diagnosis Code I45.9 Conduction disorder, unspecified 2016 2017 2018 2019 Billable/Specific Code Applicable To Heart block NOS Stokes-Adams syndrome second[icd10data.com] Rhythm versus conduction Your heart rhythm is the way your heart beats. Conduction is how electrical impulses travel through your heart, which causes it to beat.[heart.org]

    Potential problems include " myocarditis, heart conduction block, and arrhythmia.[physio-pedia.com] A repeat ECG showed a first-degree AV block with a markedly prolonged PR interval of greater than 400 ms.[journals.lww.com] He was noted to possibly have subtle Brugada pattern on EKG with prolonged PR interval of 252ms. A procainamide challenge was equivocal.[onlinejacc.org]

    Disorders of conduction may manifest as slowed conduction (1st degree), intermittent conduction failure (2nd degree), or complete conduction failure (3rd degree).[ecg.utah.edu] This is different than a first-degree atrioventricular, or AV, block, which shows a prolonged PR interval.[healio.com] Mobitz Type 1 (Wenckebach) • Gradual prolongation of PR interval until nonconducted p wave • RP-PR reciprocity • Lengthening of the PR interval at progressively shorter decrements[slideshare.net]
