95 Possible Causes for Left Axis Deviation, Premature Ventricular Contraction

  • Hypertrophic Cardiomyopathy

    ECG: Findings also may include right or left axis deviation, conduction abnormalities, sinus bradycardia with ectopic atrial rhythm and atrial enlargement.[] ., and Gustav Eles, D.O. 1 Citing Article A 68-year-old woman presented with symptoms of palpitations and was found to have frequent premature ventricular contractions and[] axis deviation, and deep, narrow so-called "needle-like" q waves, typically in leads I, L, V5 and V6.[]

  • Ventricular Tachycardia

    […] or even right axis deviation.[] KEYWORDS: catheter ablation; normal heart; premature ventricular contractions; ventricular fibrillation; ventricular tachycardia [Indexed for MEDLINE] Free full text[] The ECG typically shows right axis deviation, with a left bundle branch block pattern.[]

  • Cardiomyopathy

    Biatrial enlargement Left ventricular hypertrophy or biventricular enlargement Left bundle branch block ( RBBB can also occur). Left axis deviation.[] ., and Gustav Eles, D.O. 1 Citing Article A 68-year-old woman presented with symptoms of palpitations and was found to have frequent premature ventricular contractions and[] deviation (right or left) Conduction abnormalities (P-R prolongation, bundle-branch block) Sinus bradycardia with ectopic atrial rhythm Atrial enlargement Abnormal and prominent[]

  • Ventricular Bigeminy

    VT is diagnosed by the presence of fusion and capture beats, AV dissociation, left axis deviation and compensatory pauses.[] […] introduction a premature ventricular contraction or ventricular ectopic beat is a cardiac contraction that is generally premature or occurs before the expected sinus QRS complex[] axis deviation Plateau pulse Postoperative His bundle tachycardia Postoperative sinoatrial disease Postural orthostatic tachycardia syndrome Pulse deficit Pulse irregular[]

  • Myocardial Infarction

    Response to ECG Challenge This ECG shows sinus rhythm with left-axis deviation in the frontal plane (left anterior hemiblock) with notches in the S wave, a broad R S in V[]

  • Mitral Valve Prolapse

    […] bundle branch block/right axis deviation morphology was induced.[] BACKGROUND: In patients with frequent premature ventricular contractions (PVCs), little is known about the profile of PVCs and the outcome of treatment in patients with mitral[] A variable arrhythmia spectrum was observed in prolapse during monitoring: premature ventricular contractions in 18 (58%), supraventricular arrhythmias in 11 (35%), and bradyarrhythmias[]

  • 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 ([] Normally the heartbeat is initiated in the SA node of the atrium but initiation can also occur in the Purkinje fibres of the ventricles, giving rise to premature ventricular[] Left axis deviation.[]

  • Bifascicular Block

    […] with right bundle-branch block and left axis deviation (56% or 55/98).[] ventricular contractions.[] premature complex, ventricular premature contraction, ventricular extrasystole, ventriculare premature beat, premature ventriculare complex, premature ventricular contraction[]

  • Acute Myocarditis

    Cine sequences in three long axes and a stack of short-axis views covering the left and right ventricle were analyzed using a dedicated feature tracking algorithm.[] Afterwards, the parameters maxT2 (the highest segmental T2 value) and madSD (the mean absolute deviation (MAD) of the pixel-SDs) were calculated for each subject.[]

  • Congenital Aortic Valve Stenosis

    References: [3] [7] [4] Diagnostics ECG Nonspecific for AS Signs of left ventricular hypertrophy (e.g., left axis deviation, positive Sokolow-Lyon index ) Chest x-ray Findings[] Wolfe et al. reported that multiform ventricular premature contraction, couplet, and ventricular tachycardia are serious arrhythmias that are associated with sudden cardiac[] […] of left ventricular hypertrophy, such as left ventricular enlargement and rounded heart apex, usually only in decompensated aortic stenosis, and possibly left atrial enlargement[]
