91 Possible Causes for Left Axis Deviation in USA

  • Left Anterior Fascicular Block
    Right Axis Deviation Left Axis Deviation

    axis deviation. … It is manifested on the ECG by left axis deviation. … The delayed and unopposed activation of the remainder of the LV now results in a shift in the QRS axis leftward and superiorly, causing marked left axis deviation.[1] [2]

  • Tricuspid Atresia
    Left Axis Deviation

    life holosystolic murmur due to the VSD left axis deviation on electrocardiography and left ventricular hypertrophy (since it must pump blood to both the pulmonary and systemic … Left ventricular volume overload is relieved. … Left ventricular overloading is present in all TA cases.[3] [4]

  • Ostium Primum Atrial Septal Defect
    Right Axis Deviation Left Axis Deviation

    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. … deviation is generally found in primum ASD, but an RSR pattern (M pattern) in V1 is characteristic. … As left and right atrial pressures equalize, the jugular venous pressure reflects left atrial pressure.[5] [6]

  • Noonan Syndrome

    ., left anterior hemiblock, left axis deviation). … The mean final heights were 167 and 153 cm for men and women, respectively, which is approximately 2 standard deviations below normal.[7] [8]

  • Atrial Septal Defect
    Left Axis Deviation

    In ostium primum ASD, it shows left axis deviation and right bundle branch block. … In sinus venosus ASD, it shows left axis deviation and a negative P wave in lead III. … In addition to the PR prolongation, individuals with a primum ASD have a left axis deviation of the QRS complex, while those with a secundum ASD have a right axis deviation[9] [10]

  • Left Ventricular Hypertrophy
    Left Axis Deviation

    axis deviation and left ventricular strain and left atrial enlargement.  … Left ventricular hypertrophy (LVH) is thickening of the heart muscle of the left ventricle of the heart, that is, left-sided ventricular hypertrophy. … Left ventricular hypertrophy (LVH) is basically an increase in the size of the left ventricle.[11] [12]

  • Morbid Obesity
    Left Axis Deviation

    diseases: Sleep apnea, respiratory infections, bronchial asthma, and obesity hypoventilation syndrome  Cardiovascular diseases: Essential hypertension, coronary artery disease, left[13]

  • Left Ventricular Outflow Obstruction
    Left Axis Deviation
  • Hypertrophic Cardiomyopathy
    Left Axis Deviation

    Common electrocardiographic findings include ST-T wave abnormalities and left ventricular hypertrophy, axis deviation (right or left), conduction abnormalities (P-R prolongation … The thrombus generally forms in the left atrium, most commonly the left auricle. … left ventricle and left atrium, causing back pressure and interstitial congestion in the lungs.[14] [15]

  • Congenital Aortic Valve Stenosis
    Left Axis Deviation

    The electrocardiogram could reveal left ventricular hypertrophy, left bundle branch block, ST segment depression, and negative T waves. … on the left ventricle (with LVH being the expected response to chronic pressure loads on the left ventricle no matter what the cause). … When the left ventricle expands again, the aortic valve closes and prevents the blood in the aorta from flowing backward (regurgitation) into the left ventricle.[16] [17]
