239 Possible Causes for Left Axis Deviation, Right Ventricular Hypertrophy

  • Ostium Primum Atrial Septal Defect

    Hypertrophy.[en.wikipedia.org] ventricular hypertrophy.[babiesonline.co.za] deviation is generally found in primum ASD, but an RSR pattern (M pattern) in V1 is characteristic.[ipfs.io]

  • Endocardial Cushion Defect

    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[merckmanuals.com] 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]

  • Atrial Septal Defect

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

  • 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 ([merckmanuals.com] 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[slideshare.net] Left axis deviation.[lifeinthefastlane.com]

  • Tetralogy of Fallot

    axis deviation and left ventricular hypertrophy requires both atrial septal defect and ventricular septal defect Treatment Medical prostaglandin E1 indication for all patients[step1.medbullets.com] , aortic dextroposition, and right ventricular hypertrophy.[ncbi.nlm.nih.gov] Conduction Abnormalities Seven patients had complete right-bundle-branch block and left-axis deviation (bifascicular block) at the time of hospital discharge.[nejm.org]

  • 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 ventricular hypertrophy is actually more common than LPFB and may cause ECG findings similar to LPFB. LPFB may imitate inferior infarction.[ecgwaves.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]

  • Right Ventricular Outflow Obstruction

    The ECG showed left axis deviation and left ventricular (LV) hypertrophy pattern (Panel A) in the absence of an obvious cause.[e-coretvasa.cz] All six fetuses with severe pulmonary stenosis and four fetuses with pulmonary atresia had right ventricular hypertrophy.[jhu.pure.elsevier.com] An initial electrocardiogram showed sinus bradycardia (50 beats per minute), a left axis deviation with an inferior axis, and low voltage in the limb leads.[ekjm.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] Postmortem examination of the ram’s heart showed a pentalogy of Fallot, consisting of a pulmonic stenosis, a ventricular septal defect, an overriding aorta, a right ventricular[vetline.de] If pulmonary hypertension is present, right ventricular hypertrophy and right axis deviation might also be present.[thecardiologyadvisor.com]

  • Inferior Wall Myocardial Infarction

    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] Other causes of similar ECG changes include: Right ventricular hypertrophy can cause large R waves in the early V leads.[patient.info] deviation) Left anterior fascicular block (may see small q-waves in anterior chest leads) Acute pericarditis (the ST segment elevation may mimic acute transmural injury)[ecg.utah.edu]
