247 Possible Causes for Wide QRS Complex

  • 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[]

  • Premature Ventricular Contraction

    […] is much slower, creating a wide QRS complex.[] A premature ventricular complex is recognized on the ECG as an abnormal and wide QRS complex occurring earlier than expected in the cardiac cycle.[] Wide complexes; because they come from the ventricles and do not use the normal ventricular conduction system, action potentials need to travel from myocyte to myocyte, which[]

  • 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[] These altered electrical forces produce a wide QRS complex (greater than 0.12 seconds in duration) with an abnormal morphology.[] 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.[]

  • Amitriptyline

    She was in comatose, had generalized tonic clonic seizure, ventricular tachycardia, and wide QRS complexes.[] There was blood pressure 140/80 mmHg, heart rate 140 beats-per-min, temperature 103 F, Glasgow coma scale 10/15, wide complex tachycardia with QRS duration of 178 ms in electrocardiography[]

  • Procainamide

    QRS complex (probably ventricular) tachycardia.[] Population Patients 18 years of age presenting with a regular, wide QRS complex ( / 120 ms) tachycardia / 120 bpm and with good hemodynamic tolerance (SBP / 90 mm Hg, absence[] Wide QRS complex tachycardia. Reapraisal of a common clinical problem . Ann Intern Med 1988 ; 109 : 905 – 912 . 16 .[]

  • 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.[] 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[] QRS complex lasting greater than 0.12 seconds.[]

  • Ventricular Arrhythmia

    When confronted with a wide-QRS-complex tachycardia it can be difficult to differentiate between a supraventricular tachycardia with aberrancy or ventricular tachycardia .[] The timing of the premature wide QRS complex is also important because aberrantly conducted QRS complexes only occur early in the cardiac cycle during the refractory period[] ECGpedia Jump to: navigation , search Author(s) J.S.S.G. de Jong Moderator J.S.S.G. de jong Supervisor some notes about authorship Ventricular arrhythmias are almost allways wide-QRS-complex[]

  • Coronary Ischemia

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

  • Ventricular Tachycardia

    Philosophy, merits and limitations of a novel method for wide QRS complex tachycardia differentiation, based on a scoring system and called the ventricular tachycardia (VT[] Any wide QRS complex tachycardia (QRS 0.12 sec) should be considered VT until proved otherwise.[] 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.[]

  • Wolff-Parkinson-White Syndrome

    The electrocardiogram showed a PR interval of 0.10 second and wide QRS complexes suggestive of an accessory pathway.[] We report a 68-year-old man who presented with heart failure and atrial fibrillation (AF) with rapid ventricular response and wide QRS complexes.[] A 12-lead electrocardiogram showed irregular wide QRS complex tachycardia with a slur at the initial portion of the QRS complex.[]
