88 Possible Causes for Incomplete Right Bundle Branch Block, Right Axis Deviation

  • Cor Pulmonale

    Right axis deviation and low voltage may be noted in patients with pulmonary emphysema.[health.am] […] deviation and incomplete right bundle branch block Changes in cardiac conduction due to right-sided hypertrophy Echocardiography Normal heart size To show ventricular hypertrophy[medical-dictionary.thefreedictionary.com] […] axis deviation due to right ventricular hypertrophy Incomplete or complete right bundle branch block In some cases, P pulmonale S1Q3 pattern in acute cor pulmonale Chest[amboss.com]

  • Chronic Obstructive Pulmonary Disease

    […] ventricular hypertrophy right axis deviation dominant R wave in V1 with an amplitude 7mm often associated with "P pulmonale" ( right atrial enlargement ) multifocal atrial[radiopaedia.org] deviation 110 without right bundle branch block; or some combination of these.[merckmanuals.com] […] laterally (to V5 or V6) deep S waves in the lateral leads (I, aVL, V5, V6) low QRS voltage amplitude of QRS complexes 5 mm in the limb leads or 10 mm in the precordial leads right[radiopaedia.org]

  • Recurrent Pulmonary Embolism

    Focal oligemia, cardiomegaly and plump pulmonary arteries on chest X-ray films, right axis deviation, clockwise rotation, ST-segment depression and T-wave inversion on electrocardiograms[ncbi.nlm.nih.gov] Review of EKGs showed a trend of increasing right axis deviation with recovery and recurrences during the previous 9 years and a current incomplete right bundle branch block[ncbi.nlm.nih.gov] […] interval 0.24 sec), an incomplete right bundle branch block and non-specific ST-segment abnormalities: 1 mm ST elevations in DI, DII and aVL. ( Fig. 1 ) The chest radiography[tmj.ro]

  • Pulmonary Embolism

    P pulmonale, right and left axis deviation, S 1 S 2 S 3 and S 1 Q 3 T 3 patterns, low voltage and clockwise rotation were specific, but not sensitive for APE.[ncbi.nlm.nih.gov] […] and complete right bundle branch block [RBBB], and T-wave inversion in leads V1-V4, plus ST elevation in lead aVR and atrial fibrillation suggestive of RV strain from acute[ncbi.nlm.nih.gov] […] and complete right bundle branch block [RBBB], and T‐wave inversion in leads V1–V4, plus ST elevation in lead aVR and atrial fibrillation suggestive of RV strain from acute[doi.org]

  • Ostium Primum Atrial Septal Defect

    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.[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]

  • Acute Cor Pulmonale

    Rightward shift of the QRS axis towards 90 degrees (vertical axis) or beyond ( right axis deviation ).[lifeinthefastlane.com] […] or complete right bundle branch block (2) S waves in leads I and aVL of 1.5 mm (3) a shift in the transition zone in the precordial leads to V5 (4) Q waves in leads III and[ispub.com] […] axis deviation due to right ventricular hypertrophy Incomplete or complete right bundle branch block In some cases, P pulmonale S1Q3 pattern in acute cor pulmonale Chest[amboss.com]

  • Patent Ductus Arteriosus

    His chest X-ray showed cardiomegaly and enlargement of the left pulmonary hilum, and an electrocardiogram revealed sinus tachycardia with incomplete right bundle branch block[elsevier.pt]

  • Right Ventricular Hypertrophy

    Example 4 Right ventricular hypertrophy in a patient with arrhythmogenic right ventricular cardiomyopathy (ARVC): Right axis deviation.[lifeinthefastlane.com] 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]

  • Patent Foramen Ovale

    deviation of the QRS complex while those with a secundum ASD have a right axis deviation of the QRS complex.[marmur.com] A common finding in the ECG is the presence of incomplete right bundle branch block, which is so characteristic that if it is absent, the diagnosis of ASD should be reconsidered[en.wikipedia.org] […] can cause an increased distance of internodal conduction from the SA node to the AV node. 5 In addition to the PR prolongation, individuals with a primum ASD have a left axis[marmur.com]

  • Pulmonary Hypertension

    Surface electrocardiogram showed right atrial and ventricular overload with right axis deviation.[ncbi.nlm.nih.gov] These signs include the following: Right-axis deviation R/S ratio greater than 1 in lead V1 Right atrial enlargement as indicated by an increased P-wave amplitude in lead[emedicine.com] […] atrial enlargement, right axis deviation, right ventricular hypertrophy, and characteristic ST depression and T-wave inversions in the anterior leads.[emedicine.medscape.com]
