254 Possible Causes for 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.[] PR interval and normal QRS in LGL.[] Causes of short PR interval: Lown-Ganong-Levine Syndrome.[]

  • 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[] However the main basis for this diagnosis is the ECG which associates short PR interval and widening of QRS complex with a delta wave.[] PR interval (usually 0.1 second or less; occasionally normal) together with a prolonged QRS complex with a slurred initial component (delta wave).[]

  • Wolff-Parkinson-White Syndrome

    Diagnosis is typically when an electrocardiogram (ECG) show a short PR interval and a delta wave.[] Abstract 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[] Electrocardiography (ECG) of patients with WPW syndrome portrays a short PR interval and a wide QRS interval with a delta wave.[]

  • 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[] Note the short PR interval, delta wave, and wide QRS complex.[] 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[]

  • Barth Syndrome

    A recent electrocardiogram (ECG) was essentially unremarkable ( Figure 1 ), showing in sinus rhythm a slightly short PR interval (0.12 ms), and mildly high voltage QRS, in[]

  • Glycogen Storage Disease Type 2

    The electrocardiogram typically shows short PR intervals and tall QRS complexes; true Wolf-Parkinson-White syndrome has been reported in some patients.[] ECG shows a short PR interval as well as very tall QRS complexes.[] In addition, the electrocardiogram (ECG) may show conduction abnormalities including a short PR interval, characteristic tall QRS complexes, and Wolf-Parkinson-White syndrome[]

  • Fabry Disease

    A short PR interval with RBBB pattern is also suspicious.[] General physicians and cardiologists should consider the diagnosis of FD in patients with LVH, cardiomyopathy, and conduction abnormalities, including short PR intervals and[] PR interval) Arrhythmias, hypertrophic cardiomyopathy (young adults) Red-purple, non-blanching vascular skin lesions .[]

  • Hypertrophic Cardiomyopathy

  • Cushing's Disease

    Summary Epidemiology Exact prevalence is unknown. Prevalence of endogenous CS is estimated at around 1/26,000, with CD representing more than two-thirds of all cases. Recent data suggests that mild CD is more common than previously thought. Clinical description The female-to-male ratio of CD is 4-5:1, except in[…][]

  • Graves Disease

    BMJ Case Rep. 2017 Sep 7;2017. pii: bcr-2017-220153. doi: 10.1136/bcr-2017-220153. Abstract We present two patients with Graves' disease and concurrent myasthenia gravis. The impact of the dual diagnosis on the clinical course and the potential for a delayed diagnosis of myasthenia gravis is discussed. Patient 1, a[…][]
