121 Possible Causes for Short PR Interval, Syncope

  • Hypertrophic Cardiomyopathy

    syncope, palpitations, and edema.[] PR interval ( First-degree (PR 0.21 s, not shortening with hyperventilation), second-degree, or third-degree atrioventricular block To assess whether the changing pattern[] Symptoms include dyspnea, chest pain, syncope, and sudden death.[]

  • Myocardial Infarction

    ., referred pain), a sense of substernal heaviness, squeezing or pressure, shortness of breath (dyspnea), fatigue, fainting (syncope), nausea, sweating (diaphoresis), anxiety[] […] usually lasts 20 min, often is diffuse, not localized, not positional, not affected by movement of the region and it may be accompanied by dyspnoea, diaphoresis, nausea or syncope[] […] or near syncope without other cause Impairment of cognitive function without other cause An MI can occur at any time of the day, but most appear to be clustered around the[]

  • Acute Myocardial Infarction

    Abstract An individual experiencing dyspnoea or syncope at high altitude is commonly diagnosed to have high-altitude pulmonary edema or cerebral edema.[] Chest pain may, typically, be associated with the following; dyspnea, epigastric pain, palpitations, diaphoresis, syncope or presyncope and disorientation.[] ., referred pain), a sense of substernal heaviness, squeezing or pressure, shortness of breath (dyspnea), fatigue, fainting (syncope), nausea, sweating (diaphoresis), anxiety[]

  • Fabry Disease

    The prevalence of angina was 23 vs. 22%; palpitations and arrhythmias 27 vs. 26%; exertional dyspnoea 23 vs. 23%; and syncope 2 vs. 4%, in women and men, respectively (all[] PR interval) Arrhythmias, hypertrophic cardiomyopathy (young adults) Red-purple, non-blanching vascular skin lesions .[] General physicians and cardiologists should consider the diagnosis of FD in patients with LVH, cardiomyopathy, and conduction abnormalities, including short PR intervals and[]

  • Wolff-Parkinson-White Syndrome

    Clinical clues to the diagnosis include a young patient with previous episodes of palpitations, rapid heart rate, or syncope.[] 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[] RP in the AP, may play a relevant role to determine the rate of ventricular response during atrial fibrillation, eventually leading to extremely fast ventricular rates, syncope[]

  • Pheochromocytoma

    Typical signs include headache, flushing, palpitation, sweating, nervousness, hyperglycemia, nausea, vomiting, and syncope.[]

  • Preexcitation Syndrome

    METHODS: Anterograde conduction through atrioventricular AP was identified at electrophysiological study (EPS) in 712 patients, studied for tachycardia (n 316), syncope (n[] 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[] PR interval (usually 0.1 second or less; occasionally normal) together with a prolonged QRS complex with a slurred initial component (delta wave).[]

  • Orthostatic Hypotension

    , the most common cause of syncope.[] The most likely mechanism was an impaired cardiac filling with a short diastolic time due to a very prolonged PR interval, a somewhat "pseudo-pacemaker syndrome".[] Arrhythmias may cause severe syncope, characterized by an increased risk of mortality.[]

  • Syncope

    […] on Syncope of the ESC. 1, 2 The subdivision of syncope is based on pathophysiology as follows: View this table: In this window In a new window Table 1 Causes of 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[] 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[]

  • Lown-Ganong-Levine Syndrome
