98 Possible Causes for Incomplete Right Bundle Branch Block, Left Axis Deviation

  • 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] Right ventricle hypertrophy markers or incomplete right bundle branch block may be present.[symptoma.com] deviation is generally found in primum ASD, but an RSR pattern (M pattern) in V1 is characteristic.[ipfs.io]

  • Atrial Septal Defect

    When an ostium primum atrial defect is present, the ECG reveals left axis deviation.[healio.com] The impact of incomplete right bundle branch block (IRBBB) and ASD diameter (  5 and  5 mm) on ASD diagnosis were also explored.[ncbi.nlm.nih.gov] 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.[symptoma.com]

  • Conduction Disorder of the Heart

    No other cause for left axis deviation is identified. Left posterior fascicular (or hemi) block Right axis deviation (mean frontal plane axis clockwise to 90 ).[patient.info] right bundle branch block.[healio.com] If left axis deviation is present, think about left anterior fascicular block , and if right axis deviation is present, think about left posterior fascicular block in addition[ecg.utah.edu]

  • Endocardial Cushion Defect

    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 septal defect[ncbi.nlm.nih.gov] 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[heart.bmj.com] Left axis deviation Biventricular hypertrophy Chest X-ray Cardiomegaly with increased pulmonary vascular markings Treatment Close the atrial and/or ventricular septal defects[echocardiology.org]

  • Anomalies of Coronary Artery Origin

    His electrocardiogram revealed normal sinus rhythm at a rate of 80 beats/min, left axis deviation, left atrial abnormality, and T-wave inversion in lead V 6 .[read.nxtbook.com] Resting electrocardiogram demonstrated incomplete right bundle branch block and T wave inversion in inferior leads.[ispub.com] The resting electrocardiogram demonstrated incomplete right bundle branch block and T wave inversion in the inferior leads.[ispub.com]

  • Right Ventricular Hypertrophy

  • Left Anterior Fascicular Block

    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[ncbi.nlm.nih.gov] right bundle block?[healthtap.com] 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 .[en.wikipedia.org]

  • Patent Foramen Ovale

    Individuals with a sinus venosus ASD exhibit a left axis deviation of the P wave (not the QRS complex).[marmur.com] Incomplete right bundle branch block is frequently present. Crochetage (a notch seen in QRS in leads II and III) can be seen in secundum ASD cases.[thecardiologyadvisor.com] A common finding in the ECG is the presence of incomplete right bundle branch block , which is so characteristic that if it is absent, the diagnosis of ASD should be reconsidered[en.wikipedia.org]

  • Familial Progressive Cardiac Conduction Defect

    No other cause for left axis deviation is identified. Left posterior fascicular (or hemi) block Right axis deviation (mean frontal plane axis clockwise to 90 ).[patient.info] bundle branch block.
