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

  • 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] Normal axis or right axis deviation due to right ventricular diastolic overload. Right atrial abnormality ( may not be observed in children ).[metealpaslan.com]

  • Cor Pulmonale

    Right axis deviation and low voltage may be noted in patients with pulmonary emphysema.[health.am] ECG shows the following changes: In acute pulmonary heart disease : right axial deviation, complete or incomplete right bundle branch block, sinus tachycardia, reversal of[doctortipster.com] […] 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]

  • Pulmonary Hypertension

    Surface electrocardiogram showed right atrial and ventricular overload with right axis deviation.[ncbi.nlm.nih.gov] Right axis deviation (short arrow), increased P-wave amplitude in lead II (black arrowhead), and incomplete right bundle branch block (white arrowhead) are highly specific[aafp.org] 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.medscape.com]

  • Right Ventricular Hypertrophy

    An ECG with right ventricular hypertrophy may or may not show a right axis deviation on the graph. [1] Contents 1 Symptoms 2 Causes 3 Diagnosis 4 Treatment 5 References 6[en.wikipedia.org] 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]

  • 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] EKG showed right axis deviation, a new incomplete right bundle branch block (IRBBB), clockwise rotation, and right heart strain with inverted T waves in V1–V4 ( Figure 2 )[nature.com]

  • 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] Incomplete right bundle branch block is frequently present. Crochetage (a notch seen in QRS in leads II and III) can be seen in secundum ASD cases.[thecardiologyadvisor.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]

  • Acute Cor Pulmonale

    Rightward shift of the QRS axis towards 90 degrees (vertical axis) or beyond ( right axis deviation ).[lifeinthefastlane.com] […] 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] […] 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]

  • Conduction Disorder of the Heart

    No other cause for left axis deviation is identified. Left posterior fascicular (or hemi) block Right axis deviation (mean frontal plane axis clockwise to 90 ).[patient.info] right bundle branch block.[healio.com] There was a left bundle branch block in both and a left axis duration in 3M and right axis deviation in NM.[jpma.org.pk]

  • Left Posterior Fascicular Block

    axis deviation, alongside several other findings involving the QRS complex.[symptoma.com] Incomplete right bundle branch block (RBBB pattern) is accompanied by left posterior fascicular block. QRS axis is about 120 degrees (right axis deviation).[metealpaslan.com] Is an ECG result of abnormal left axis deviation, left anterior fascicular block and incomplete right bundle branch block problematic?[justanswer.com]

  • Atrial Septal Defect

    Surface electrocardiogram showed right atrial and ventricular overload with right axis deviation.[ncbi.nlm.nih.gov] The impact of incomplete right bundle branch block (IRBBB) and ASD diameter (  5 and  5 mm) on ASD diagnosis were also explored.[ncbi.nlm.nih.gov] bundle branch block pattern (rsR' in V1), and right axis deviation.[patient.info]
