133 Possible Causes for Prolonged PR Interval, Rheumatic Heart Disease

  • Cardiomyopathy

    disease Arterial hypertension Peripartum cardiomyopathy Valvular heart disease Infections C oxsackie B virus myocarditis Rheumatic heart disease Chagas disease Genetic predisposition[] […] such as heart failure, cardiogenic shock, or arrhythmias.[] Dilated cardiomyopathy Epidemiology Most common cardiomyopathy Incidence : 6/100,000 per year Sex: (approx. 3:1) Etiology Idiopathic (approx. 50%) Secondary cause Coronary heart[]

  • Rheumatic Fever

    November 2001 to update the WHO Technical Report 764 on Rheumatic Fever and Rheumatic Heart Disease.[] We report on a 10-year-old boy who presented with progressive right side involuntary movements, an apical systolic murmur, prolonged PR interval, and elevated antistreptolysin[] Initial attack patients have higher incidence of prolonged PR-interval (67 vs. 12%, P 0.049) and longer duration of admission to diagnosis (5 vs. 2 days, P 0.05).[]

  • Rheumatic Heart Disease

    Rheumatic heart disease refers to a group of heart disorders that develop as a complication of rheumatic fever.[] ECG reveals no diagnostic changes, but 20% of patient show a prolonged PR interval. 15.[] In some patients, rheumatic heart disease is a possible causal association.[]

  • Ankylosing Spondylitis

    It is an autoimmune disorder, an inflammatory arthritic disorder, a rheumatic disease, and one of the various spondylarthropathies.[] Ankylosing spondylitis (AS) is a systemic rheumatic disease, meaning it affects the entire body.[] Ankylosing spondylitis is an inflammatory condition that can affect various areas of the body (such as the heart, the eyes, the lungs, and kidneys) but which mainly attacks[]

  • Atrial Fibrillation

    Most important risk factors for atrial fibrillation are high age, arterial hypertension, diabetes mellitus, heart failure and rheumatic heart disease.[] A history of syncope, sinus bradycardia, PR interval prolongation, and bundle-branch block raise concerns for a risk of bradyarrhythmia during antiarrhythmic drug therapy.[] The major factors that increase the risk of atrial fibrillation are: Age Coronary artery disease Rheumatic heart disease High blood pressure Diabetes An excess of thyroid[]

  • Atrial Septal Defect

    Prevention of infective endocarditis: guidelines from the American Heart Association: a guideline from the American Heart Association Rheumatic Fever, Endocarditis, and Kawasaki[] Complete heart block may be revealed in ostium primum type Large ASD may have prolonged PR interval 18.[] Individuals with atrial septal defects may have a prolonged PR interval (a first-degree heart block).[]

  • AV Block Mobitz I

    Acquired heart block has many possible causes, including heart attack (the most common cause), heart disease, an enlarged heart (cardiomyopathy), heart failure and rheumatic[] The hallmark of Mobitz type 1 block is the gradual prolongation of PR intervals before a block occurs. Mobitz type 2 block has constant PR intervals before blocks occur.[] It can be seen in myocardial ischemia, propranolol use, digitalis use, rheumatic fever, and chronically in ischemic heart disease and other structural diseases (amyloidosis[]

  • AV Block Mobitz II

    Rheumatic fever and sarcoidosis Symtoms: Irregular heart rhythm Dizziness/syncope Chest pain Fatigue Shortness of breath Treatment: Stop medications if they are the cause[] Commonly used terminology includes: First degree AV block – Delayed conduction from the atrium to the ventricle (defined as a prolonged PR interval of 200 milliseconds) without[] Every-other-P wave conducts – as determined by the presence of a fixed ( albeit prolonged ) PR interval preceding each QRS complex on the tracing.[]

  • Second Degree Atrioventricular Block

    It can be seen in myocardial ischemia, propranolol use, digitalis use, rheumatic fever, and chronically in ischemic heart disease and other structural diseases (amyloidosis[] This case demonstrates the need for caution and interval cardiac testing when adding LCM to other AEDs known to prolong the PR interval.[] On the surface ECG this is realized through a prolonged PR interval.[]

  • Sick Sinus Syndrome

    Cardiomyopathies: ischaemia, myocardial infarction, myocarditis, pericarditis, rheumatic heart disease, surgical injury, arteritis. Surgical injury.[] Friedreich’s ataxia Muscular dystrophy Scleroderma Mitral valve prolapse Rheumatic heart disease Acute myocarditis Congenital heart disease Familial sinus node disease Surgical[] […] conditions that can involve the heart such as rheumatic fever, pericarditis, Chagas disease, or myocarditis Infiltrative heart diseases such as sarcoidosis, amyloidosis,[]
