68 Possible Causes for Short PR Interval, Wide QRS Complex

  • Wolff-Parkinson-White Syndrome

    The electrocardiogram showed a PR interval of 0.10 second and wide QRS complexes suggestive of an accessory pathway.[] 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[] We report a 68-year-old man who presented with heart failure and atrial fibrillation (AF) with rapid ventricular response and wide QRS complexes.[]

  • 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[] 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[] QRS complex (fusion of early ventricular activation from the accessory pathway, and later activation from the AV node) Various other abnormalities, including ventricular[]

  • Lown-Ganong-Levine Syndrome

    complex ( 120 msec); regular, wide QRS complex ( 120 msec); may not see any P-wave activity in either type (atypical or typical) Atypical AVNRT: RP interval PR interval;[] The PR interval is short.

Short PR interval in a 7 years-old boy.[] Case 1, with short PR interval and narrow QRS complexes had a short AH interval and intermittent right bundle-branch block.[]

  • Right Bundle Branch Block

    In a type I block with wide QRS complex ( 0.12sec), the block can be in the His-Purkinje system in 60-70% of the cases.[] PR interval) and incomplete right bundle branch block (IRBBB).[] These are the criteria for multifocal atrial tachycardia MAT, also known as chaotic atrial rhythm,1 chaotic atrial tachycardia,2 and chaotic atrial mechanism.3 The wide QRS[]

  • Coronary Ischemia

    Step 6: QRS complex – If Q waves are prominent, consider myocardial infarction. Wide QRS complexes denote bundle branch block or pre-excitation.[] 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.[]

  • Bifascicular Block

    Note the short PR interval and the delta wave.[] Pacer spikes are not readily seen, but the width of the QRS, the axis of the wide QRS complexes (left), and the timing (after a pause) all support the paced rhythm diagnosis[] 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[]

  • Preexcitation Syndrome

    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[] However the main basis for this diagnosis is the ECG which associates short PR interval and widening of QRS complex with a delta wave.[] . * a wide QRS complex.[]

  • Acute Myocardial Infarction

    Note the AV dissociation in the rhythm strip in lead V1 at the bottom; this is diagnostic for VT in the setting of a wide QRS complex tachycardia, but not always seen.[]

  • Myocardial Infarction

    BACKGROUND Various physical and emotional factors have been previously described as triggers for stress induced cardiomyopathy. However, acute myocardial infarction as a trigger has never been reported. CASE REPORT We describe four patients who presented with an acute myocardial infarction, in whom the initial[…][]

  • First-Degree Atrioventricular Block

    An additional defect in the His-Purkinje system is indicated on the ECG by a wide QRS complex.[] Surprisingly, with longer follow-up of the same cohort, only a short PR interval ( Table 1 ).[] Mont L. et al: A new approach to the differential diagnosis of a regular tachycardia with a wide QRS complex.
