31 Possible Causes for Left Anterior Fascicular Block in USA

  • Endocardial Cushion Defect
    Left Anterior Fascicular Block

    An endocardial cushion defect, also known as the atrioventricular septal defect, encompasses several congenital heart disease forms of abnormal atrioventricular septation and formation of a single atrioventricular valve. Cyanosis is principally seen in milder forms, whereas congestive heart failure and even death may…[1]

  • Cardiac Amyloidosis
    Left Anterior Fascicular Block

    Normal-voltage electrocardiogram (ECG) with a left anterior fascicular block and thickened left ventricular (LV) walls on echocardiography are characteristic.[2]

  • Acute Myocardial Infarction
    Left Anterior Fascicular Block

    Acute myocardial infarction (AMI) ,colloquially referred to as a heart attack, is an irreversible death of a myocardial segment sequel to persistent occlusion and inadequacy of coronary blood flow to the heart. AMI typically presents with central chest pain which may radiate to the neck, left arm, jaw, and shoulders.…[3]

  • Ostium Primum Atrial Septal Defect
    Left Bundle Branch Block Left Anterior Fascicular Block

    The ostium primum atrial septal defect consists of the absence of the interatrial septum in the atrioventricular canal portion, which causes interatrial left to right shunting. The malformation may occur by itself or in association with an inlet ventricular septal defect, as part of an atrioventricular septal defect.…[4]

  • Atrial Septal Defect
    Left Anterior Fascicular Block

    Atrial septal defect (ASD) is a congenital malformation characterized by a communication between the atrial chambers of the heart. History ASDs are usually asymptomatic in infancy and childhood. In most cases, the symptoms manifest by the third decade of life. Due to paucity of symptoms, most times ASDs go…[5]

  • Myocardial Infarction
    Left Anterior Fascicular Block

    Myocardial infarction, commonly referred to as heart attack, is a condition characterized by necrosis of the heart muscles due to development of ischemia that stays on for prolonged periods. Such a condition develops when the heart does not receive oxygen and blood due to blockage in the coronary…[6]

  • Left Anterior Fascicular Block

    Left anterior fascicular block (LAFB) is presented by irregular contraction of heart muscles, a condition arising as a result of a defect of the anterior half of the bundle … There is no treatment for bi-fascicular block, which occurs when right bundle branch block and left anterior fascicular block take place at the same time. … When a left anterior fascicular block occurs, the initial septal activation and the activation of the inferior and apical areas are oriented anteriorly and inferiorly, with[7]

  • Bifascicular Block

    Most commonly, it refers to a combination of right bundle branch block (RBBB) and either left anterior fascicular block (LAFB) or left posterior fascicular block (LPFB), with[8]

  • Left Posterior Fascicular Block

    Left bundle branch block Left anterior fascicular block Ma FS, Ma J, Tang K, et al.[9]

  • Heart Block
