966 Possible Causes for P Wave Absent, Patient Appears Acutely Ill

  • Atrial Flutter

    Cases with thrombi in multiple cardiac chambers are rare. We report an extremely rare case in which thrombi were formed in all four cardiac chambers at the same time. A 55-year-old man presented with biventricular failure and liver dysfunction. A 12-lead ECG and an echocardiogram revealed an old anteroseptal[…][]

  • Acute Kidney Failure

    Therefore urine will be dilute ( Other Tests An ECG is important to look for changes of hyperkalaemia (absent p-wave, tall tented T-wave, wide QRS complex becoming sinusoidal[]

  • Overdose

    As serum potassium rises, the ECG may progressively develop flattened or absent P waves, a prolonged PR interval, widened QRS complex, deepened S waves, and merging of S and[] […] flaccid paralysis, paresthesia, depressed deep tendon reflexes, or respiratory difficulties, 200 – 202 the first indicator of hyperkalemia may be the presence of peaked T waves[]

  • Acute Atrial Infarction

    Deviations in PTa segment (Ta is atrial repolarization wave; deviation of Ta wave relative to preceding P wave) has been proposed as the criteria to diagnose atrial infarction[] ECG criteria Changes in ECG maybe absent due to low voltage and over-shadowing by the ventricular depolarization.[]

  • Acute Cor Pulmonale

    Virtually absent R waves in the right precordial leads (SV1-SV2-SV3 pattern).[] Peaked P waves. Low QRS voltages (most obvious in the limb leads). Clockwise rotation (transitional lead V6).[] Peaked P waves in the inferior leads 2.5 mm (P pulmonale) with a rightward P-wave axis (inverted in aVL) Clockwise rotation of the heart with a delayed R/S transition point[]

  • Acute Aortic Regurgitation

    The mitral A wave was absent in five patients with acute regurgitation.[] RESULTS: Early mitral flow peak velocity was higher in patients with acute regurgitation (p 0.001).[]

  • Tachyarrhythmia

    P waves are absent and replaced by irregular electrical activity. The ventricular rate is irregular and chaotic.[] P waves are absent and replaced by irregular electrical activity. The ventricular rate is irregular and chaotic. Figure 1 Electrocardiogram showing atrial fibrillation.[]

  • Acute Bronchitis

    Pneumonia Patients with pneumonia often have a higher fever than patients with acute bronchitis, may appear more ill, and have rales on lung examination.[] CXR will detect an infiltrate from pneumonia that will not be present in acute bronchitis.[] Allergic rhinitis Patients with allergic rhinitis often have postnasal drip causing a cough.[]

    Missing: P Wave Absent
  • Accidental Hypothermia

    His bundle electrocardiography was performed on a patient with accidental hypothermia on whom the standard electrocardiogram (ECG) showed absent P waves, prominent J waves[]

  • Upper Respiratory Infection

    This article has no abstract; the first 100 words appear below. Acute pharyngitis is one of the most common illnesses for which patients visit primary care physicians.[]
