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

  • 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[] 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[] An increased PR interval, a widened QRS complex, and a prolonged QT interval signal progressing hypothermia.[]

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

  • Sinus Tachycardia

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

  • Ventricular Tachycardia

    Answers Rhythm: Regular Rate: 150 P Wave: absent PR interval: n/a QRS: Wide and bizarre Interpretation: Ventricular Tachycardia[] Many things can cause palpitations, like: Alcohol Caffeine Exercise Stress Dehydration Medication Fever Thyroid disorders Smoking Dietary supplements like goldenseal, oleander[] 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[]

  • Hyperkalemia

    We report a neonate with hyponatremia, severe dehydration and refractory life threatening hyperkalemia who was treated with dietary sodium chloride supplementation, potassium[] 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[] Example of bradycardia with absent or flattened p waves in hyperkalemia. Care of Dr. Smith’s ECG blog.[]

  • Premature Ventricular Contraction

    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.[] Yeah, I had worked out that morning-after dehydration from a good session did send the PVCs into overdrive even before my cardiologist pointed out that reserach had also picked[] […] or a prolonged QT interval. children left ventricular function premature ventricular contraction This is a preview of subscription content, log in to check access.[]

  • Hypokalemic Nephropathy

    […] 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[] […] abnormalities. salt-losing nephropathy intrinsic renal disease causing abnormal urinary sodium loss in persons ingesting normal amounts of sodium chloride, with vomiting, dehydration[] QT interval ).[]

  • Sinus Arrest

    I am no doctor. but there is a renewed interest of research on the effects of dehydration on our electrical system I know this is not your diagnosis (v tach) but here is a[] Certain medications may prolong the QT interval predisposing the patient to ventricular tachycardia 4.[] 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[]

  • Bifascicular Block

    I’ve done it several times for borderline ECGs, especially for syncope, and particularly when there is no prodrome and the history does not suggest dehydration or vasovagal[] Citalopram might ring alarm bells for you, given its propensity to prolong the QT interval.[] ECG changes: An absent P wave and often an absent QRS complex are seen.[]

  • SHORT Syndrome

    , especially in the precordial leads (V2 to V4); the ST segment was virtually absent [ 15 , 17 ] and, consequently, the interval between the end of the T wave and the following[] They may also become dehydrated, which can be life threatening.[] Ibutilide and sotalol, IKr blockers, have been demonstrated to be ineffective to prolong the QT interval (18).[]
