62 Possible Causes for P Wave Absent, Ventricular Fibrillation

  • 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] We defined adverse events as symptomatic bradycardia, ventricular tachycardia, ventricular fibrillation, cardiopulmonary resuscitation (CPR) and/or death.[ncbi.nlm.nih.gov] Ventricular fibrillation The end game for untreated hyperkalemia is chaotic depolarisation of ventricular myocardium: ventricular fibrillation.[acadoodle.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] Here, a young woman with prior episodes of auditory stimulus-induced syncope presented with LQTS and ventricular fibrillation (VF) with hypomagnesaemia and hypocalcaemia after[ncbi.nlm.nih.gov] Ventricular fibrillation. 3.[ecgwaves.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] Patients of ventricular fibrillation usually present with sudden loss of consciousness.[symptoma.com] […] basis of the fact that ventricular fibrillation itself is common, idiopathic ventricular fibrillation accounts for an appreciable mortality.[en.wikipedia.org]

  • Atrial Fibrillation

    P waves are absent and replaced by irregular electrical activity. The ventricular rate is irregular and chaotic.[web.archive.org] […] complications; treatment outcome; ventricular fibrillation/etiology/prevention & control[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

    fibrillation.[ncbi.nlm.nih.gov] […] especially short-long-short sequence protocol in inducing ventricular fibrillation in these patients are also discussed.[ncbi.nlm.nih.gov] For instance, atrial fibrillation with preexcited conduction needs specific consideration of medication choice to avoid potential degeneration into ventricular fibrillation[ncbi.nlm.nih.gov]

  • Atrial Standstill

    Diagnostic criteria of atrial standstill Absent P waves both on surface and intracardiac ECG. Junctional bradycardia.[metealpaslan.com] Here we report a case of Brugada syndrome with ST elevation in the right precordial and inferior leads accompanied by atrial standstill and spontaneous ventricular fibrillation[ncbi.nlm.nih.gov] EKG Absent P waves. JVP Absent A waves.[medical-dictionary.thefreedictionary.com]

  • Sinus Arrest

    Occasionally and when the P waves are absent for a relatively long time, escape beats appear, as other groups of myocardial cells undertake the pacemaking process for a brief[symptoma.com] A trial evaluating the benefit, if any, of amiodarone on attempted resuscitation after out-of-hospital cardiac arrest with ventricular fibrillation or ventricular tachycardia[medical-dictionary.thefreedictionary.com] waves: Sinus P waves with basic rhythm; absent during pause PR interval: Normal (0.12 to 0.20 second) with basic rhythm; absent during pause QRS complex: Normal (0.10 second[aibolita.com]

  • Ventricular Tachycardia

    Answers Rhythm: Regular Rate: 150 P Wave: absent PR interval: n/a QRS: Wide and bizarre Interpretation: Ventricular Tachycardia[ekg.academy] Some medications may reduce the frequency of ventricular fibrillation/ventricular tachycardia.[healthcentral.com] Rhythm Regular Rate Fast (100-250 bpm) P Wave Absent PR Interval Not measurable QRS Wide ( 0.10 sec), bizarre appearance Notes[practicalclinicalskills.com]

  • Familial Atrial Fibrillation

    […] and supraventricular dysrhythmias. 4 Interestingly, two of the affected family members in the study of familial atrial fibrillation had evidence of ventricular dilatation[nejm.org] The molecular basis for atrial fibrillation is unknown, and palliative therapy is used to control the ventricular rate and prevent systemic emboli.[ncbi.nlm.nih.gov] ventricular AP abbreviation.[ncbi.nlm.nih.gov]

  • 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] ) and experienced ventricular fibrillation, from which he was successfully defibrillated.[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]
