227 Possible Causes for Wide QRS Complex

  • Supraventricular Tachycardia with Aberrant Conduction

    Several criteria have been described for differentiation between VT and SVT in the presence of a wide QRS complex.[e-arrhythmia.org] The wide QRS complexes are examples of tachycardia-dependent LBBB aberration, not runs of ventricular tachycardia. Note the morphology of the wide beats.[afghanheart.wordpress.com] Aberration is seen as bundle branch block pattern (wide QRS complex).[metealpaslan.com]

  • Ventricular Tachycardia

    KEYWORDS: Algorithms; VT score; Ventricular tachycardia; Wide QRS complex tachycardia[ncbi.nlm.nih.gov] Abstract BACKGROUND In the differential diagnosis of a tachycardia with a wide QRS complex (greater than or equal to 0.12 second) diagnostic mistakes are frequent.[doi.org] And you notice that on EKG you have these course wide QRS complexes. And a wide QRS complex means that the QRS complex is greater than three small boxes.[khanacademy.org]

  • Wolff-Parkinson-White Syndrome

    Abstract 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] The electrocardiogram showed a PR interval of 0.10 second and wide QRS complexes suggestive of an accessory pathway.[ncbi.nlm.nih.gov] Elective cardioversion restored sinus rhythm, and the ECG showed a wide QRS complex, short PR interval, and delta wave, indicating the presence of an accessory pathway and[ncbi.nlm.nih.gov]

  • Right Bundle Branch Block

    QRS Wave Wide QRS Complex QRS Wave Wide QRS Complex These are the criteria for multifocal atrial tachycardia MAT, also known as chaotic atrial rhythm,1 chaotic atrial tachycardia[symptoma.com] 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[ncbi.nlm.nih.gov] 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.[ncbi.nlm.nih.gov]

  • Third Degree Atrioventricular Block

    ECG features of 3rd degree AV block On the ECG P-waves have no relation to the QRS complexes . The QRS complexes may be normal or wide.[ecgwaves.com] If the block is below the bifurcation of the His bundle , the QRS complexes are wide.[en.my-ekg.com] If the block is lower in the AV node, a ventricular rhythm may exist, with wide QRS complexes. 3 Atrioventricular Block: Complete Heart Block Rate: Atrial rate will be independent[ems12lead.com]

  • Ventricular Bigeminy

    The signal that originated in the ventricle can be distinguished from a normal signal by its wide QRS complex and lack of a P wave.[wisegeek.com] Depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide QRS complexes can be uniform or polymorphic, and the ventricular[ncbi.nlm.nih.gov] -Wide QRS Complex (shape of QRS and T depends on location of ectopic focus) PREMATURE VENTRICULAR CONTRACTION CRITERIA ?[quizlet.com]

  • Hyperkalemia

    QRS complexes.[ncbi.nlm.nih.gov] complex tachycardia.[ncbi.nlm.nih.gov] Electrocardiogram (ECG) showed a pacemaker (PMK)-induced rhythm, with loss of atrial capture and wide QRS complexes.[ncbi.nlm.nih.gov]

  • Bifascicular Block

    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[ecgguru.com] The QRS complexes are wide both due to preexcitation and due to right bundle branch block, which persists during preexcitation.[the-medical-dictionary.com] The QRS duration is wide at 138. There is a rsR’ complex in lead V1.[ecgmedicaltraining.com]

  • Adrenal Insufficiency

    If potassium is above 7.0 mmol/L and hyperkalaemic ECG changes are present (eg. peaked T waves wide QRS complex flattened P waves), treat with either of the following: give[rch.org.au]

  • Left Bundle Branch Block

    However, in some patients, LBBB may vary with heart rate, and during episodes of AF in LBBB, aberrant ventricular conduction, or wide QRS complex tachycardia (Ashman beats[ncbi.nlm.nih.gov] These altered electrical forces produce a wide QRS complex (greater than 0.12 seconds in duration) with an abnormal morphology.[meds.queensu.ca] A 12-lead ECG in the ER showed sinus tachycardia at 118 beats/min, wide QRS complexes, peaked T waves and left bundle branch block-like pattern.[cardiologyres.org]
