188 Possible Causes for Incomplete Right Bundle Branch Block

  • 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]

  • Secondary Cardiomyopathy

    A previous ECG (two years ago) showed incomplete right bundle branch block morphology but no other abnormality.[radcliffecardiology.com] Discussion The admission ECG shows sinus tachycardia at a rate of 148bpm, incomplete right bundle branch block, ST-segment depressions in the inferior and anterolateral leads[radcliffecardiology.com]

  • Right Ventricular Hypertrophy

    In contrast, when an incomplete right bundle branch block exists, the rSR' pattern is a relatively sensitive but nonspecific predictor of RVH.[ncbi.nlm.nih.gov] bundle branch block in the right precordial chest leads may signal the development of RVH In the limb leads right axis deviation develops and at times prominent Q waves simulating[wikidoc.org] right bundle branch block ST-T wave abnormalities ("strain") in inferior leads Right atrial hypertrophy/overload (“P pulmonale”) S greater than R in leads I, II, III, particularly[ncbi.nlm.nih.gov]

( Fig. 1 ) The chest radiography[tmj.ro] A chest film 2 weeks earlier had revealed a right-sided cutoff of pulmonary vasculature; the current film showed right-sided pleural effusion.[ncbi.nlm.nih.gov]
