33 Possible Causes for Preexcitation Syndrome, Short PR Interval

  • Lown-Ganong-Levine Syndrome

    The PR interval is short. Click here for a more detailed ECG ECG 3. Short PR interval in a 7 years-old boy.[] Preexcitation syndrome These pathways can lead the excitation both anterograde and retrograde, which allows a reentry circuit.[] The Lown-Ganong-Levine syndrome (LGL) is usually considered in a class of preexcitation syndromes that includes the Wolff-Parkinson-White syndrome (WPW), LGL, and Mahaim-type[]

  • Wolff-Parkinson-White Syndrome

    Wolff-Parkinson-White (WPW) syndrome is defined as the presence of an accessory atrioventricular pathway which is manifested as delta waves and short PR interval on electrocardiography[] It seems reasonable, therefore, to revisit the clinical and electrophysiologic role of preexcitation syndromes in current practice.[] Electrocardiography (ECG) of patients with WPW syndrome portrays a short PR interval and a wide QRS interval with a delta wave.[]

  • Hypertrophic Cardiomyopathy

    Incidence of preexcitation phenomenon of the Wolff-Parkinson-White syndrome type, which may cause palpitations, is increased. Bundle branch block is common.[]

  • Preexcitation Syndrome

    The classic electrocardiogram in Wolff-Parkinson-White (WPW) syndrome is characterized by a short PR interval and prolonged QRS duration in the presence of sinus rhythm with[] The main tool used to establish the preexcitation syndrome diagnosis is the 12-lead electrocardiogram.[] PR interval (usually 0.1 second or less; occasionally normal) together with a prolonged QRS complex with a slurred initial component (delta wave).[]

  • Graves Disease

    BACKGROUND: Graves' disease (GD) is associated with excess morbidity and mortality, but little is known about unnatural manners of death and the potential relation with Graves' orbitopathy (GO). This study investigated the risk of unnatural death in Graves' patients with and without orbitopathy compared to matched[…][]

  • Ebstein Malformation

    The classic WPW ECG pattern consists of : A short PR interval (rapid AV conduction through the accessory pathway) Delta wave (initial slow ventricular activation due to fiber[] interval; may be normal/short in patients with Wolff-Parkinson-White syndrome Right bundle branch block and/or low voltage QRS complex Imaging studies The following imaging[] Intermittent/paroxysmal supraventricular tachycardia, atrial flutter/fibrillation, ventricular tachycardia Abnormal P waves consistent with right atrial enlargement Prolonged PR[]

  • Atrial Tachyarrhythmia with Short PR Interval

    Five additional family members had short PR intervals with normal QRS, and eight other family members had borderline short PR intervals.[] Abstract Lown Ganong Levine (LGL) which is a preexcitation syndrome is defined with paroxysmal tachycardia, dyspnea, anxiety, angina, and the complaint of fatigue accompanied[] Lown-Ganong-Levine Syndrome Lown-Ganong-Levine (LGL) syndrome is a preexcitation syndrome producing supraventricular tachycardia that is neither atrial fibrillation nor atrial[]

  • Familial Progressive Cardiac Conduction Defect

    syndromes and all types of ventricular and supraventricular tachycardias.[] Recently, we identified the genetic cause of a familial arrhythmogenic syndrome characterized by ventricular preexcitation and tachyarrhythmias (Wolff–Parkinson–White syndrome[] […] arrhythmias, electrophysiologic testing, mapping and navigation modalities, ablation energy sources, sinus node dysfunction, conduction disturbances, atrial tachyarrhythmias, preexcitation[]

  • Syncope

    So here goes: W is Wolff-Parkinson-White syndrome – look for a short PR interval or delta wave: O is obstructed AV pathway – look for 2nd or 3rd degree block: or axis deviation[] , Brugada syndrome, preexcitation) Syncope occurring without warning; recovery immediate on awakening May occur in any position Patient taking drugs, especially antiarrhythmics[] short PR: WPW long PR : AV conduction block narrow, deep QRS: HCM wide QRS Epsilon waves: arrhythmogenic RV hypertrophy wide QRS: Vtach,WPW, BBB QT interval: long QT syndrome[]

  • Diffuse Intraventricular Block

    […] normal PR interval 0.12 to 0.20 s (3 - 5 small squares) for short PR segment consider Wolff-Parkinson-White syndrome or Lown-Ganong-Levine syndrome (other causes - Duchenne[] syndromes Rightward axis Left posterior fascicular block (LPFB) Lateral myocardial infarction Right ventricular hypertrophy (RVH) Acute lung disease (e.g.[] QT interval Increased u-wave amplitude Prolonged PR-interval Sinus bradycardia ECG changes typical for digoxin intoxication are: Bradyarrhythmias: AV block.[]
