234 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] Note the short PR interval .[en.wikipedia.org] ECG Presentation • Short PR interval • Slurred initial upstroke of QRS – delta wave • Relatively normal , narrow terminal QRS –main QRS deflection • Slight widening of QRS[slideshare.net]

  • 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] The combination of a short PR interval and an abnormally long QRS complex comprises the ECG diagnosis of ventricular pre-excitation.[frca.co.uk]

  • 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[…][orpha.net]

  • Graves Disease

    Graves' disease, also known as toxic diffuse goiter, is an autoimmune disease that affects the thyroid. It frequently results in and is the most common cause of hyperthyroidism. It also often results in an enlarged thyroid. Signs and symptoms of hyperthyroidism may include irritability, muscle weakness, sleeping[…][en.wikipedia.org]

  • Myocardial Infarction

    An acute myocardial infarction is caused by necrosis of myocardial tissue due to ischaemia, usually due to blockage of a coronary artery by a thrombus. Most myocardial infarctions are anterior or inferior but may affect the posterior wall of the left ventricle to cause a posterior myocardial infarction. Nearly half[…][patient.info]
