135 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.[patient.info] ., 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[nejm.org] Common electrocardiographic findings include ST-T wave abnormalities and left ventricular hypertrophy, axis deviation (right or left), conduction abnormalities (P-R prolongation[symptoma.com]

  • Cardiomyopathy

    Biatrial enlargement Left ventricular hypertrophy or biventricular enlargement Left bundle branch block ( RBBB can also occur). Left axis deviation.[lifeinthefastlane.com] ., 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[nejm.org] Common etiologies include chronic untreated atrial fibrillation with rapid ventricular response and frequent (several thousand daily) premature ventricular contractions.[emedicine.medscape.com]

  • Ventricular Bigeminy

  • Mitral Valve Prolapse

    […] bundle branch block/right axis deviation morphology was induced.[ncbi.nlm.nih.gov] 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 valve prolapse[ncbi.nlm.nih.gov] A variable arrhythmia spectrum was observed in prolapse during monitoring: premature ventricular contractions in 18 (58%), supraventricular arrhythmias in 11 (35%), and bradyarrhythmias[annals.org]

  • Ventricular Tachycardia

    They all have an RBBB shape because of an origin in the left ventricle. The most common type is shown in panel A. The frontal QRS axis shows left axis deviation.[heart.bmj.com] Mapping identified a deep premature ventricular contraction focus in the anterolateral papillary muscle, an area that has been previously identified as difficult to treat[ncbi.nlm.nih.gov] However, certain patients with frequent premature ventricular contractions (PVCs) or VT and tachycardiomyopathy should be considered for ablation before ICD implantation because[ncbi.nlm.nih.gov]

  • Flecainide

    The patient presented with a mild mitral regurgitation and normal left ventricular function. He had incomplete left bundle branch block with left-axis deviation.[ncbi.nlm.nih.gov] Flecainide causes a dose-related and plasma concentration-related decrease in single and multiple premature ventricular contractions and can suppress recurrence of ventricular[mayomedicallaboratories.com] Case reports of ventricular proarrhythmic effects in patients treated with flecainide for atrial fibrillation/flutter have included increased premature ventricular contractions[goodrx.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] (PJC) and premature ventricular contractions(PVC) Typically benign.[smartypance.com] Abbreviations: AV : atrioventricular AVR : accelerated ventricular rhythm ECG : electrocardiogram PAC : premature atrial contraction PVC : premature ventricular contraction[pedsinreview.aappublications.org]

  • Dilated Cardiomyopathy

    Biatrial enlargement Left ventricular hypertrophy or biventricular enlargement Left bundle branch block ( RBBB can also occur). Left axis deviation.[lifeinthefastlane.com] Flecainide and amiodarone markedly reduced premature atrial and ventricular contractions in four patients.[ncbi.nlm.nih.gov] O’Grady is greater than 50 PVCs (premature ventricular contractions) per hour, however this study is on-going.[dpca.org]

  • Paroxysmal Supraventricular Tachycardia

    A resting electrocardiogram showed a right bundle branch block and left axis deviation with a delta wave.[ncbi.nlm.nih.gov] Premature Ventricular Contractions A less serious type of ventricular arrhythmia is a premature ventricular contraction (PVC).[texasheart.org] axis deviation , ectopic focus that alternates between the anterior superior and posterior inferior fascicles, and a right bundle branch block pattern in lead V 1 ; seen[medical-dictionary.thefreedictionary.com]
