7,942 Possible Causes for Left Bundle Branch Block

  • Left Bundle Branch Block

    In left bundle branch block, activation of the intraventricular septum is reversed and electrical impulses to the left ventricle are delayed.[meds.queensu.ca] What is left bundle branch block?[fairview.org] "Electrocardiography Left Bundle Branch Block (LBBB)" .[en.wikipedia.org]

  • Upper Respiratory Infection

    The right and left bronchial tubes branch off from the trachea and go to the right and left lungs.[healthline.com] Swelling of the epiglottis is dangerous because it can block the flow of air into the trachea.[healthline.com]

  • Tetralogy of Fallot

    Common post-surgical complications include 6 : conduction abnormalities right bundle branch block (RBBB): 80-90% of cases bifascicular block: 15% of cases premature ventricular[radiopaedia.org] Electrical conduction abnormalities: Every patient with tetralogy of Fallot has right bundle branch block secondary to the congenital ventricular septal defect.[emedicinehealth.com] Patients can develop slowing of the heart’s conduction (electrical) system abnormalities called right bundle branch block, abnormal heart rhythms from the upper cardiac chambers[nationwidechildrens.org]

  • Ebstein Malformation

    branch block pattern Pre-excitation due to right-sided accessory pathways – characteristic WPW ECG findings may also be seen, as discussed above Low-voltage QRS in the right-sided[pedclerk.bsd.uchicago.edu] There may be tall and broad P waves (right atrial enlargement) and complete or incomplete right bundle-branch block.[patient.info] The abnormal development of tricuspid valve results in several activation abnormalities including delayed intra atrial conduction, right bundle branch block, ventricular pre-excitation[apicareonline.com]

  • Coarctation of the Aorta

    Fetal complete heart block.[fetalultrasound.com] Other arteries to the head and arms branch off the aortic arch.[healthofchildren.com] The narrowing, or coarctation, blocks normal blood flow to the body.[cdc.gov]

  • Ostium Primum Atrial Septal Defect

    When you suspect a patient has an ASD based on the findings of an incomplete Right Bundle Branch Block with a rSr' or rSR' the next thing you should do is examine the frontal[en.wikipedia.org] Incomplete or complete right bundle branch block is encountered in most cases.[remedyland.com] Features also seen on the EKG include Right Atrial Enlargement, PR prolongation and advanced AV block.[en.wikipedia.org]

  • Tricuspid Atresia

    […] one of the arm arteries), and one of the branch Pulmonary Arteries.[rch.org.au] This atrial septal defect is needed to unload the blocked right atrium and allows the mixing of blood from the right and left atria.[pted.org] Blood then flows from the right atrium to the left atrium, through the mitral valve.[healio.com]

  • Anomalies of Coronary Artery Origin

    Single coronary artery with anomalous origin of the right coronary artery as a branch from the left anterior descending artery: a very rare coronary anomaly.[iranjradiol.com] A single left coronary artery arising from the left coronary sinus is a rare anomaly, with the RCA arising from either the left main stem or the branches downstream from the[read.nxtbook.com] The distal portion of the vessel reached the crux cordis bifurcating into the posterior descending and the posterolateral branches (dominant right coronary artery).[invasivecardiology.com]

  • Acute Myocarditis

    One patient had left bundle-branch block.[nejm.org] […] may also be seen. 20 The presence of Q waves, a new left bundle branch block and prolonged QRS duration of 120msec is associated with higher rates of cardiac death or heart[jpma.org.pk] ECGs were evaluated for atrial fibrillation (AF), AV-block, bundle-branch block, waves, and ST-abnormalities.[kjim.org]
