49 Possible Causes for Short PR Interval, Wide QRS Complex

  • Wolff-Parkinson-White Syndrome

    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] We report a 68-year-old man who presented with heart failure and atrial fibrillation (AF) with rapid ventricular response and wide QRS complexes.[ncbi.nlm.nih.gov] Electrocardiography (ECG) of patients with WPW syndrome portrays a short PR interval and a wide QRS interval with a delta wave.[ncbi.nlm.nih.gov]

  • Myocardial Infarction

    In cross-sectional studies in the general population, 15 to 40% of patients with ECG evidence of past myocardial infarction (MI) do not give a history of typical cardiac symptoms [ 1, 2, 3 ]. Mortality rates in patients with such “silent” MIs have been reported as higher than, similar to, or lower than those in[…][doi.org]

  • Acute Myocardial Infarction

    Ventricular septal rupture (VSR) is a rare but fatal complication of acute myocardial infarction (AMI) with an associated mortality that ranges from 41% to 80%. The treatment consists of supplemental oxygenation, afterload reduction, intraaortic balloon pump, and surgical repair. In selected patients, extracorporeal[…][ncbi.nlm.nih.gov]

  • 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[ncbi.nlm.nih.gov] Diagnostic criteria for WPW-type pre-excitation All of the following three criteria must be fulfilled for a diagnosis to be made: 1) P-R interval 2) Abnormally wide QRS complex[frca.co.uk] 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]
