49 Possible Causes for P Wave Absent, Wide QRS Complex

  • Hyperkalemia

    Role of inducing K loss via the GI tract in the management of hyperkalemia Setting Recommendations Hyperkalemia with severe ECG changes (e.g. absent P waves, wide QRS complex[doi.org] QRS complexes.[ncbi.nlm.nih.gov] Example of bradycardia with absent or flattened p waves in hyperkalemia. Care of Dr. Smith’s ECG blog.[emergencymedicinecases.com]

  • Electrolyte Imbalance

    U waves B. Absent P waves C. Elevated T waves D. Elevated ST segment 57. A. Obtaining a controlled IV infusion pump B. Monitoring urine output during administration C.[proprofs.com]

  • Atrial Standstill

    Diagnostic criteria of atrial standstill Absent P waves both on surface and intracardiac ECG. Junctional bradycardia.[metealpaslan.com] Abstract We report a 55-year-old female patient who presented with no P waves but with a wide QRS complex escape rhythm at 44 beats/min and prolonged QTc of 0.55 seconds on[ncbi.nlm.nih.gov] EKG Absent P waves. JVP Absent A waves.[medical-dictionary.thefreedictionary.com]

  • Atrial Fibrillation

    P waves are absent and replaced by irregular electrical activity. The ventricular rate is irregular and chaotic.[web.archive.org] QRS complexes and prominent repolarization.[ncbi.nlm.nih.gov] P waves are absent and replaced by irregular electrical activity. The ventricular rate is irregular and chaotic. Figure 1 Electrocardiogram showing atrial fibrillation.[aafp.org]

  • Atrial Flutter

    Abstract We report the case of a 67-year-old female with a wide QRS complex tachycardia at 180 bpm.[ncbi.nlm.nih.gov] QRS complex, and regular rhythm, especially when considering pharmacologic treatment.[ncbi.nlm.nih.gov] Consider atrial flutter even with wide QRS complexes Atrial flutter can produce a wide-complex tachycardia, especially in the setting of hyperkalemia .[ems1.com]

  • Ventricular Tachycardia

    Answers Rhythm: Regular Rate: 150 P Wave: absent PR interval: n/a QRS: Wide and bizarre Interpretation: Ventricular Tachycardia[ekg.academy] KEYWORDS: Algorithms; VT score; Ventricular tachycardia; Wide QRS complex tachycardia[ncbi.nlm.nih.gov] Rhythm Regular Rate Fast (100-250 bpm) P Wave Absent PR Interval Not measurable QRS Wide ( 0.10 sec), bizarre appearance Notes[practicalclinicalskills.com]

  • Supraventricular Tachycardia with Aberrant Conduction

    waves Absent P waves Table 17 Wide QRS Complex Ventricular tachycardia (VT) is uncommon in children but can be rapidly fatal.[nhcps.com] 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]

  • Ventricular Fibrillation

    Answers Rhythm: Irregular Rate: Unable to determine P Wave: absent PR interval: absent QRS: absent Interpretation: Ventricular Fibrillation (Fine) Description The morphologic[ekg.academy] The QRS complexes are wide and have an abnormal morphology.[fpnotebook.com] QRS complexes and prominent repolarization.[ncbi.nlm.nih.gov]

  • Ventricular Bigeminy

    The P wave will be absent. Premature Ventricular Complex - Bigeminy Premature Ventricular Complex - Trigeminy Premature Vent.[ekg.academy] 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] P Waves may be present or absent. P Waves are usually not seen if the rate is increased. If present, the P Waves have no relation to the QRS complexes of the V. Tach.[nurseslearning.com]

  • Wolff-Parkinson-White Syndrome

    Sometimes, the QRS complex may be normal, delta waves may be absent and p waves may be typically inverted on lateral and inferior leads.[symptoma.com] 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] . • Ventricular Premature Contractions can initiate orthodromic tachycardia • On ECG findings, • the delta wave is absent, • QRS complex is normal, • P waves are inverted[slideshare.net]
