250 Possible Causes for Short PR Interval

  • Wolff-Parkinson-White Syndrome

    The syndrome is characterized by a short PR interval and a long QRS interval with a delta wave.[fpnotebook.com] 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[ncbi.nlm.nih.gov] Definition (MSH) A form of ventricular pre-excitation characterized by a short PR interval and a long QRS interval with a delta wave.[fpnotebook.com]

  • 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[revespcardiol.org]

  • 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.[metealpaslan.com] PR interval.[thehealthscience.com] The syndrome described by Lown, Ganong, and Levine in 1952 associated the occurrence of tachycardia with presence of a short PR interval and normal QRS.[emedicine.medscape.com]

  • Preexcitation Syndrome

    PR interval (usually 0.1 second or less; occasionally normal) together with a prolonged QRS complex with a slurred initial component (delta wave).[medical-dictionary.thefreedictionary.com] Short PR interval . Normal QRS complex. Norma T wave.[en.my-ekg.com] However the main basis for this diagnosis is the ECG which associates short PR interval and widening of QRS complex with a delta wave.[ncbi.nlm.nih.gov]

  • 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[pedclerk.bsd.uchicago.edu] 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[emedicine.medscape.com] Intermittent/paroxysmal supraventricular tachycardia, atrial flutter/fibrillation, ventricular tachycardia Abnormal P waves consistent with right atrial enlargement Prolonged PR[emedicine.medscape.com]

  • 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.[ncbi.nlm.nih.gov] interval: Short Congestive heart failure Cardiomyopathy: Vacuolar; Cardiomegaly, Biventricular hypertrophy Glycogen: Increased in myocardium Phosphorylase kinase activity[neuromuscular.wustl.edu] […] from ATP depletion Activates glycolysis & fatty acid uptake during hypoxic stress or metabolic demand Non-lysosomal cardiac glycogenosis Clinical Onset: Neonatal Cardiac PR[neuromuscular.wustl.edu]

  • Cushing's Disease

    Cushing's disease (CD) is the most common cause of endogenous Cushing's syndrome. Transsphenoidal surgery (TSS) is the first choice of treatment. Predicting prognosis after treatment can benefit further strategies of management, but currently there is no convenient predictor. This study aims to investigate[…][ncbi.nlm.nih.gov]

  • Graves Disease

    Thyrotoxicosis is established risk factor for osteoporosis due to increased bone turnover. Glucocorticoids often administered for Graves' orbitopathy (GO) have additional negative effect on bone mineral density (BMD). Our aim was to examine the influence of thyroid hormones, TSH, TSH-receptor antibodies (TRAb)[…][ncbi.nlm.nih.gov]

  • Myocardial Infarction

    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 arteries.[…][symptoma.com]

  • Left Posterior Fascicular Block

    Bundle branch block with short PR interval in healthy young people prone to paroxysmal tachycardia.[books.google.com] Short PR Intervals A short PR interval, less than 0.12 seconds, is associated with accessory pathways between the atria and ventricles — the Wolff-Parkinson-White syndrome[nps.freeservers.com] PR interval ( 0.12s) Initial slurring of QRS complex (delta wave) representing early ventricular activation through normal ventricular muscle in region of the accessory pathway[ecg.utah.edu]
