68 Possible Causes for Hypoxia, 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] The first cause of increased PVR is chronic long-standing alveolar hypoxia which induces pulmonary vascular remodeling.[ncbi.nlm.nih.gov] […] deviation and incomplete right bundle branch block Changes in cardiac conduction due to right-sided hypertrophy Echocardiography Normal heart size To show ventricular hypertrophy[nursing.unboundmedicine.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] Presence of chronic hypoxia or cor pulmonale.[patient.info] deviation 110 without right bundle branch block; or some combination of these.[merckmanuals.com]

  • 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] Hypoxia is an independent predictor of both right ventricular dysfunction and 30-day mortality in these patients.[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]

  • Acute Cor Pulmonale

    Rightward shift of the QRS axis towards 90 degrees (vertical axis) or beyond ( right axis deviation ).[lifeinthefastlane.com] Hypercapnia, pneumonia, hypoxia, high plateau pressure, and positive end-expiratory pressure were associated with increased ACP incidence in patients with ARDS.[ejcdt.eg.net] […] 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]

  • Pulmonary Hypertension

    Surface electrocardiogram showed right atrial and ventricular overload with right axis deviation.[ncbi.nlm.nih.gov] […] hypertension on chronic exposure to hypoxia.[doi.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.com]

  • Pulmonary Fibrosis

    VEGF-A receptors and co-receptors were differentially expressed by hypoxia and hyperoxia.[ncbi.nlm.nih.gov] Abstract We report an 85-year-old male, with history of interstitial pulmonary fibrosis (IPF), who was presented with progressive dyspnea, hypoxia, and anemia of 2 months[ncbi.nlm.nih.gov] Hypoxia caused by pulmonary fibrosis can lead to pulmonary hypertension, which, in turn, can lead to heart failure of the right ventricle.[en.wikipedia.org]

  • Endocardial Cushion Defect

    Clinical features- See hemodynamics Radiography- See hemodynamics ECG- Left axis deviation Counterclockwise depolarization- as initial left to right septal depolarization[heartpearls.com] In those with severe right-sided duct-dependent lesions, closure of the ductus causes increasing hypoxia and cyanosis.[patient.info] […] atrial shunt, three leaflets with cleft in left atrioventriular valve Cardiac Auscultation Pulmonary flow murmur Atrioventricular regurgitation Electrocardiogram Left axis[echocardiology.org]

  • Right Ventricular Hypertrophy

    Example 4 Right ventricular hypertrophy in a patient with arrhythmogenic right ventricular cardiomyopathy (ARVC): Right axis deviation.[lifeinthefastlane.com] Moreover, we created cardiomyocyte-specific HEXIM1 transgenic mice and revealed that HEXIM1 ameliorates RVH and prevents RV dilatation in hypoxia-induced PAH model.[ncbi.nlm.nih.gov] 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]

  • 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] For the treatment failure of antifungals, we presume PE would aggravate ischemia and hypoxia in the fungal-infected tissue, thus limiting the access of antifungal drugs.[omicsonline.org] 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]

  • Patent Ductus Arteriosus

    PDA is common in newborns with persistent respiratory problems such as hypoxia, and has a high occurrence in premature newborns.[en.wikipedia.org] 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]
