326 Possible Causes for Right Axis Deviation

  • Asthma

    Electrocardiographic signs of right heart strain such as right axis deviation, clockwise rotation, and evidence of right ventricular hypertrophy may be observed in acute,[ncbi.nlm.nih.gov]

  • 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]

  • Cor Pulmonale

    Right axis deviation and low voltage may be noted in patients with pulmonary emphysema.[health.am] ECG dominant R wave in lead V1 10 defined as an R wave height 7 mm or R/S 1 accompanied by dominant S waves in lead V6 right axis deviation secondary repolarization abnormalities[radiopaedia.org] ECG shows tall, peaked P waves (P pulmonale), right axis deviation, and right ventricular hypertrophy. Chest x-ray: Enlarged right ventricle and pulmonary artery.[health.am]

  • 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] axis deviation, right bundle branch block (RBBB), or deep S-waves in I with Q waves in III and inverted T waves in III ('S1,Q3,T3' pattern).[patient.info] Right axis deviation and S 1 Q 3 T 3 pattern were observed in only APE. Low voltage was more frequent in APE and TC. However, the frequencies of these findings were low.[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] 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] […] heart strain), - right axis deviation - s wave (I and aVL) 1.5mm - Q wave in III and aVF - p pulmonale - RBBB CXR: rules out other pathology, focal oligaemia, wedge density[lifeinthefastlane.com]

  • Anterior Myocardial Infarction

    […] precordial R waves) Pulmonary emphysema and cor pulmonale (loss of R waves V1-3 and/or inferior Q waves with right axis deviation) Left anterior fascicular block (may see[ecg.utah.edu] Note pathologic Q-waves in V1-4, late R wave in V1, wide S waves in lead I, and left axis deviation (-80 degrees).[ecg.utah.edu] MI Left Bundle Branch Block Often a difficult ECG diagnosis because in LBBB the right ventricle is activated first and left ventricular infarct Q waves may not appear at the[ecg.utah.edu]

  • Acute Massive Pulmonary Embolism

    His electrocardiogram showed wide-complex atrial fibrillation with rapid ventricular rate of 182, right axis deviation, right ventricular hypertrophy and inferior Q waves[epmonthly.com] […] heart strain), - right axis deviation - s wave (I and aVL) 1.5mm - Q wave in III and aVF - p pulmonale - RBBB CXR: rules out other pathology, focal oligaemia, wedge density[lifeinthefastlane.com] axis deviation T-wave inversion in the right precordial leads /- the inferior leads is seen in up to 34% of patients and is associated with high pulmonary artery pressures[radiopaedia.org]

  • Acute Cor Pulmonale

    Rightward shift of the QRS axis towards 90 degrees (vertical axis) or beyond ( right axis deviation ).[lifeinthefastlane.com] Other ECG findings in PE include right bundle-branch block, right axis deviation, atrial fibrillation, and T-wave changes ( 2, 3 ).[ispub.com] ECG dominant R wave in lead V1 10 defined as an R wave height 7 mm or R/S 1 accompanied by dominant S waves in lead V6 right axis deviation secondary repolarization abnormalities[radiopaedia.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] 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] Normal axis or right axis deviation due to right ventricular diastolic overload. Right atrial abnormality ( may not be observed in children ).[metealpaslan.com]

  • Acute Respiratory Distress Syndrome

    Abstract Severe adenovirus infection in children can manifest with acute respiratory distress syndrome (ARDS) and respiratory failure, leading to the need for prolonged mechanical support in the form of either mechanical ventilation or extracorporeal life support. Early extracorporeal membrane oxygenation (ECMO)[…][ncbi.nlm.nih.gov]
