167 Possible Causes for Short PR Interval, Syncope

  • Wolff-Parkinson-White Syndrome

    Clinical clues to the diagnosis include a young patient with previous episodes of palpitations, rapid heart rate, or syncope.[] 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[] 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[]

  • Syncope

    […] for syncope is identified.[] 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

    If they had attacks of syncope, they should not drive.[] The PR interval is short. Click here for a more detailed ECG ECG 3. Short PR interval in a 7 years-old boy.[] If ventricular tachycardia or ventricular fibrillation occurs, syncope may occur.[]

  • Hypertrophic Cardiomyopathy

    syncope, palpitations, and edema.[] Two years later, on presentation of syncope, an abnormal ventricular septal size was recorded by ultrasound scan, and was subsequently shown by magnetic resonance imaging[] Symptoms include dyspnea, chest pain, syncope, and sudden death.[]

  • Supraventricular Tachycardia

    Age 40 years, feeling of dizziness/syncope or chest pain associated with tachycardia, the absence of heart disease or short PR interval was more frequent in patients with[] This produces a short PR interval and a delta wave, as is observed in persons with Wolff-Parkinson-White (WPW) syndrome.[] We describe the case of a pregnant woman who presented syncope due to drug-refractory supraventricular tachycardia who underwent catheter ablation without the use of fluoroscopy[]

  • Tachyarrhythmia

    In patients who present with more severe symptoms, such as syncope, outpatient monitoring may be insufficient.[] Once this patient converted back to normal sinus rhythm, the classic delta wave and short PR interval was easily identifiable (Figure 2).[] ORPHA:844 Synonym(s): Atrial tachyarrhythmia with short PR interval LGL syndrome Prevalence: Inheritance: Autosomal dominant or Not applicable Age of onset: All ages ICD-10[]

  • Coronary Ischemia

    The patient was encountered by rural emergency medical service providers presenting with syncope followed by intermittent episodes of lightheadedness.[] Step 4: Intervals – Normal PR intervals are 120 milliseconds to 200 milliseconds (3 to 5 small squares). Short PR intervals suggests Wolff-Parkinson-White syndrome.[] However, this attitude was undermined by reports of cases of sudden death, AMI, angina, and syncope associated with their presence 1-4 .[]

  • Fabry Disease

    Syncope and dyspnea are also seen in a majority of the patients with cardiovascular manifestations.[] […] changes (cranial MRI) GI dysmotility with nausea, bloating and post-prandial diarrhea Hypertrophic cardiomyopathy, cardiac arrythmias Autonomic dysfunction with orthostasis or syncope[] Fabry may manifest sinus bradycardia, systolic murmurs, chest pain, dyspnea, arrhythmias, decreased heart rate variability, left ventricular hypertrophy, palpitations, and syncope[]

  • Paroxysmal Supraventricular Tachycardia

    Supraventricular tachycardia is a common dysrhythmia that can result in syncope or myocardial infarction.[] This produces a short PR interval and a delta wave, as is observed in persons with Wolff-Parkinson-White (WPW) syndrome.[] […] prompt resolution of potentially life-threatening complications in all AS patients, especially those presenting with the symptoms of palpitation, dizziness, dyspnea, or syncope[]

  • Anterior Myocardial Infarction

    The patient was confused but was able to report abdominal/dorsal pain (poorly localized) previous to the syncope.[] At the fourth day, while ST elevations returned to baseline, short PR interval and delta waves were observed on the ECG.[] […] or near-syncope.[]
