26 Possible Causes for Dehydration, P Wave Absent, Prolonged QT Interval

  • Electrolyte Imbalance

    Be aware of treatment measures for dehydration and electrolyte imbalance. Dehydration Increase fluids of any kind.[zanecohencentre.com] ECG shows prolonged QT intervals # 96.[slideshare.net] 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]

  • Accidental Hypothermia

    Regular consumption of high-energy food rich in carbohydrates aids the body in heat production, while 13-17 c (3-4L) of water a day prevents rapid dehydration from evaporation[science.jrank.org] QT interval, adjusted for HR, was prolonged in 72.8% of the cases.[ncbi.nlm.nih.gov] Abstract His bundle electrocardiography was performed on a patient with accidental hypothermia on whom the standard electrocardiogram (ECG) showed absent P waves, prominent[ncbi.nlm.nih.gov]

  • Acute Kidney Failure

    Dehydration caused by drastically reduced fluid intake or excessive use of diuretics (water pills) is a major cause of prerenal ARF.[healthcommunities.com] 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[web.archive.org] People who are dehydrated, or at risk of dehydration, may need to be given fluids via a drip.[nhs.uk]

  • Hyperkalemia

    We report a neonate with hyponatremia, severe dehydration and refractory life threatening hyperkalemia who was treated with dietary sodium chloride supplementation, potassium[ncbi.nlm.nih.gov] interval, prolonged PR interval, prolonged QRS interval, loss of P wave, sine waves and finally ventricular fibrillation (see ECG guideline for normal values for age) ECG[starship.org.nz] 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]

  • Ventricular Fibrillation

CXR: signs of left heart failure, pulmonary hypertension.[patient.info] Answers Rhythm: Irregular Rate: Unable to determine P Wave: absent PR interval: absent QRS: absent Interpretation: Ventricular Fibrillation (Fine) Description The morphologic[ekg.academy]

  • Cardiopulmonary Resuscitation

    […] position (Class IIa, LOE C-LD).updated for 20152015Position for ShockIf there is no evidence of trauma or injury (eg, simple fainting, shock from nontraumatic bleeding, sepsis, dehydration[doi.org] Prolongation of QT interval with myocardial contusion. Heart Lung 1978 ; 7 : 652 –6. Blair E , Topuzlu C, Davis JH. Delayed or missed diagnosis in blunt chest trauma.[web.archive.org] 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[doi.org]

  • Ventricular Tachycardia

    Many things can cause palpitations, like: Alcohol Caffeine Exercise Stress Dehydration Medication Fever Thyroid disorders Smoking Dietary supplements like goldenseal, oleander[m.webmd.com] The patient's initial electrocardiogram was remarkable for a prolonged QT interval, and it was discovered that multiple family members had died of cardiac events as young[ncbi.nlm.nih.gov] Answers Rhythm: Regular Rate: 150 P Wave: absent PR interval: n/a QRS: Wide and bizarre Interpretation: Ventricular Tachycardia[ekg.academy]

  • Sinus Tachycardia

    Is he dehydrated? Is there bleeding that may be associated with shock? Does he have any known medical problems?[medictests.com] BACKGROUND: The QT interval measures cardiac repolarization, and prolongation is associated with adverse cardiovascular outcomes and death.[ncbi.nlm.nih.gov] The tachycardia ECG may be unremarkable, with P waves absent (hidden in the QRS).[patient.info]

  • Hypokalemic Nephropathy

    […] abnormalities. salt-losing nephropathy intrinsic renal disease causing abnormal urinary sodium loss in persons ingesting normal amounts of sodium chloride, with vomiting, dehydration[medical-dictionary.thefreedictionary.com] QT interval ).[wikidoc.org] […] flattened/absent P waves QRS widening sine waves this can be treated with loop diuretics to increase urinary K excretion should also restrict dietary K and hyperkalemic Drugs[quizlet.com]

  • Tachyarrhythmia

    The most common causes of tachycardia that should be treated outside of the ACLS tachycardia algorithm are dehydration, hypoxia, fever, and sepsis.[acls-algorithms.com] This female neonate was born at 36 weeks of gestation and showed a markedly prolonged QT interval and transient, repeated episodes of polymorphic ventricular tachycardia.[ncbi.nlm.nih.gov] P waves are absent and replaced by irregular electrical activity. The ventricular rate is irregular and chaotic.[web.archive.org]
