80 Possible Causes for Heart Murmur, Incomplete Right Bundle Branch Block, Right 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] Patients typically are referred for evaluation of a heart murmur in childhood and generally survive well into adulthood.[emedicine.com] Right ventricle hypertrophy markers or incomplete right bundle branch block may be present.[symptoma.com]

  • Recurrent Pulmonary Embolism

    Focal oligemia, cardiomegaly and plump pulmonary arteries on chest X-ray films, right axis deviation, clockwise rotation, ST-segment depression and T-wave inversion on electrocardiograms[ncbi.nlm.nih.gov] Review of EKGs showed a trend of increasing right axis deviation with recovery and recurrences during the previous 9 years and a current incomplete right bundle branch block[ncbi.nlm.nih.gov] On physical examination, significant findings include: loud systolic murmur and palpable triple apical impulse due to palpable presystolic fourth heart sound.[en.wikipedia.org]

  • Patent Ductus Arteriosus

    His chest X-ray showed cardiomegaly and enlargement of the left pulmonary hilum, and an electrocardiogram revealed sinus tachycardia with incomplete right bundle branch block[elsevier.pt] Symptoms A heart murmur is usually the first sign of PDA newborns. A small PDA may not cause significant problems, so it is usually not treated.[preemies.about.com] , failure to thrive, tachycardia, heart murmur Complications Heart failure, Eisenmenger's syndrome, pulmonary hypertension Causes Idiopathic Risk factors Preterm birth, congenital[en.wikipedia.org]

  • Patent Foramen Ovale

    deviation of the QRS complex while those with a secundum ASD have a right axis deviation of the QRS complex.[marmur.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] Patients with large holes may have a heart murmur, either previously undetected or never evaluated.[barnesjewish.org]

  • Endocardial Cushion Defect

    Clinical features- See hemodynamics Radiography- See hemodynamics ECG- Left axis deviation Counterclockwise depolarization- as initial left to right septal depolarization[heartpearls.com] Identification of a heart murmur (most likely pansystolic, but also ejection systolic or apical mid-diastolic) during cardiac auscultation can raise sufficient clinical suspicion[symptoma.com] […] atrial shunt, three leaflets with cleft in left atrioventriular valve Cardiac Auscultation Pulmonary flow murmur Atrioventricular regurgitation Electrocardiogram Left axis[echocardiology.org]

  • Atrial Septal Defect

    At the initial visit, he presented with recurrent lower respiratory infection, heart murmur, psychomotor retardation, inverted nipples, and cerebellar atrophy.[ncbi.nlm.nih.gov] Surface electrocardiogram showed right atrial and ventricular overload with right axis deviation.[ncbi.nlm.nih.gov] The impact of incomplete right bundle branch block (IRBBB) and ASD diameter (  5 and KEYWORDS: Crochetage on R wave; Inferior leads; Pediatric; Secundum atrial septal defect[ncbi.nlm.nih.gov]

  • Cor Pulmonale

    Heart murmurs in children should be carefully analysed to prevent later incidence of this syndrome.[hxbenefit.com] Right axis deviation and low voltage may be noted in patients with pulmonary emphysema.[health.am] […] deviation and incomplete right bundle branch block Changes in cardiac conduction due to right-sided hypertrophy Echocardiography Normal heart size To show ventricular hypertrophy[nursing.unboundmedicine.com]

  • Cardiomyopathy

    Electrocardiogram showed right axis deviation, poor R-wave progression, and diffuse ST-segment elevation in the anterior leads, and cardiomegaly was observed by roentgenogram[ncbi.nlm.nih.gov] (Heart murmurs are extra or unusual sounds heard during a heartbeat.) Updated: June 22, 2016[web.archive.org] Right axis deviation suggests associated right ventricular hypertrophy (i.e. biventricular enlargement ).[lifeinthefastlane.com]

  • Right Ventricular Outflow Obstruction

    […] and incomplete right bundle branch block.[ncbi.nlm.nih.gov] Familiar and personal medical history was unremarkable except for a systolic heart murmur known since childhood.[e-coretvasa.cz] At follow-up (range, 2 months to 5 years after surgery), all patients were in New York Heart Association functional class I and all had murmurs.[ncbi.nlm.nih.gov]

  • Chronic Obstructive Pulmonary Disease

    […] ventricular hypertrophy right axis deviation dominant R wave in V1 with an amplitude 7mm often associated with "P pulmonale" ( right atrial enlargement ) multifocal atrial[radiopaedia.org] Signs of cor pulmonale include neck vein distention, splitting of the 2nd heart sound with an accentuated pulmonic component, tricuspid insufficiency murmur, and peripheral[merckmanuals.com] […] laterally (to V5 or V6) deep S waves in the lateral leads (I, aVL, V5, V6) low QRS voltage amplitude of QRS complexes 5 mm in the limb leads or 10 mm in the precordial leads right[radiopaedia.org]
