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.[] The first cause of increased PVR is chronic long-standing alveolar hypoxia which induces pulmonary vascular remodeling.[] […] deviation and incomplete right bundle branch block Changes in cardiac conduction due to right-sided hypertrophy Echocardiography Normal heart size To show ventricular hypertrophy[]

  • 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[] Presence of chronic hypoxia or cor pulmonale.[] deviation 110 without right bundle branch block; or some combination of these.[]

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

  • Acute Cor Pulmonale

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

  • Pulmonary Hypertension

    Surface electrocardiogram showed right atrial and ventricular overload with right axis deviation.[] […] hypertension on chronic exposure to hypoxia.[] 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[]

  • Pulmonary Fibrosis

    VEGF-A receptors and co-receptors were differentially expressed by hypoxia and hyperoxia.[] 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[] Hypoxia caused by pulmonary fibrosis can lead to pulmonary hypertension, which, in turn, can lead to heart failure of the right ventricle.[]

  • Endocardial Cushion Defect

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

  • Right Ventricular Hypertrophy

    Example 4 Right ventricular hypertrophy in a patient with arrhythmogenic right ventricular cardiomyopathy (ARVC): Right axis deviation.[] Moreover, we created cardiomyocyte-specific HEXIM1 transgenic mice and revealed that HEXIM1 ameliorates RVH and prevents RV dilatation in hypoxia-induced PAH model.[] In contrast, when an incomplete right bundle branch block exists, the rSR' pattern is a relatively sensitive but nonspecific predictor of RVH.[]

  • 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[] 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.[] 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[]

  • Patent Ductus Arteriosus

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