176 Possible Causes for Left Axis Deviation, Right Ventricular Hypertrophy

  • 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.[] Hypertrophy.[] ventricular hypertrophy.[]

  • Endocardial Cushion Defect

    Abstract Three groups of patients are identified in the series of secumdum atrial septal defect with left axis deviation in an analysis of 910 patients of secundum atrial[] ECG shows a superiorly directed QRS axis (eg, left axis deviation or northwest axis), frequent 1st-degree AV block, left or right ventricular hypertrophy or both, and occasional[] Left axis deviation Biventricular hypertrophy Chest X-ray Cardiomegaly with increased pulmonary vascular markings Treatment Close the atrial and/or ventricular septal defects[]

  • Atrial Septal Defect

    When an ostium primum atrial defect is present, the ECG reveals left axis deviation.[] Mild right ventricular hypertrophy Inverted P waves in Sinous Venosus type Right Bundle Branch Block is seen which is partial or complete 17.[] 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.[]

  • Left Posterior Fascicular Block

    Verapamil-sensitive, idiopathic left ventricular tachycardia (ILVT) with right bundle branch block configuration and left-axis deviation is known to be due to re-entry mechanism[] ventricular hypertrophy, or any other cause of right axis deviation - Limb lead QRS voltage should be increased in summary...[] The electrical axis will be shifted to the left (left axis deviation), ranging between -45 and -90 .[]

  • Left Anterior Fascicular Block

    Noteworthy Establishing a diagnosis of LPFB requires that there are no clinical or ECG criteria of right ventricular hypertrophy present.[] The two current criteria for diagnosis of left anterior fascicular block (LAFB) were evaluated; they are marked left axis deviation (LAD) and a delay in the time of inscription[] It is caused by only the anterior half of the left bundle branch being defective. It is manifested on the ECG by left axis deviation.[]

  • Left Ventricular Hypertrophy

    […] atrial involvement - terminal deflection of P wave in V1 is 1 box wide, and 1 box deep or more (3 points) Left axis deviation - QRS axis is -30 degrees or more negative ([] Defination:   right ventricular hypertrophy is the enlargement of heart’s right ventricle Right ventricular hypertrophy, or simply RVH, is considered to be one of the rare[] Left axis deviation.[]

  • Left Atrial Hypertrophy

    Left axis deviation probably due to LAHB 2 Reply Echocardiogram report indicated ASD; VSD; & Hypoplastic Pulmonary artery as per Dr Habib's input with the CXR version of this[] Left Axis Deviation; Left Atrial hypertrophy ; Left Bundle Branch Block; Wolf-Parkinson-White Syndrome (WPW Syndrome) Chronic Obstructive Pulmonary Disease; Left atrial hypertrophy[] LAE & Left axis deviation (common but not needed to call LVH)[]

  • Left Bundle Branch Block

    Left bundle branch block is usually associated with normal or left axis deviation.[] […] disease and right ventricular hypertrophy.[] ventricular hypertrophy.[]

  • Hypertrophic Cardiomyopathy

    […] or right ventricular hypertrophy (hypertrophy, left ventricular; hypertrophy, right ventricular), frequent asymmetrical involvement of the heart septum, and normal or reduced[] ECG: Findings also may include right or left axis deviation, conduction abnormalities, sinus bradycardia with ectopic atrial rhythm and atrial enlargement.[] Common electrocardiographic findings include ST-T wave abnormalities and left ventricular hypertrophy, axis deviation (right or left), conduction abnormalities (P-R prolongation[]

  • Right Atrial Hypertrophy
