64 Possible Causes for Prominent U Wave

Show results in: Srpski

  • Sinus Bradycardia

    Note the prominent U waves in the precordial leads, a common finding in sinus bradycardia.[]

  • Hypokalemia

    prominent U waves require hospital admission.[] Other electrocardiographic changes of hypokalemia include T wave depression and prominent U waves. Diff.Dx: A. Inadequate dietary potassium intake B.[] Findings such as T-wave flattening or prominent U waves will result in hospital admission. [3] Other tests may include: arterial blood gas basic or comprehensive metabolic[]

  • Cardiodysrhythmic Potassium-Sensitive Periodic Paralysis

    U waves in V1–V4 at rest.[] U wave; (3) at least two of the following dysmorphic features: low-set ears, wide-set eyes, a small mandible, fifth-digit clinodactyly, and syndactyly; and (4) a family member[] U waves, prolonged QU intervals, prolonged QT intervals, premature ventricular contractions, or polymorphic ventricular tachycardia.[]

  • Digitalis Toxicity

    OBJECTIVE: To document the prevalence of digitalis use and the incidence of hospitalization caused by digitalis toxicity. DESIGN: Observational cohort followed for 6 years. SETTING: Urban community. PARTICIPANTS: Persons were eligible if they were (1) enrolled in the Yale Health and Aging Project and (2) using digitalis[…][]

  • Accidental Hypothermia

    AIM OF THE STUDY: Accidental hypothermia (AH) is a complex and life threatening condition. Knowledge about epidemiology, rewarming treatments, complications and outcome is limited. This study was initiated to obtain data on causes, rewarming treatments and complications. METHODS: A retrospective cohort study of all[…][]

  • Myxedema

    Myxedema or severe hypothyroidism is clinical condition where the thyroid gland does not produce any thyroid hormone. In some cases, myxedema condition is also being referred to as underactive thyroid. Myxedema typically present with a distinct facial appearance, hoarse slow speech, and dryness of the skin. The[…][]

  • Cushing's Disease

    Cushing's disease results from prolonged overexposure of tissues to endogenous glucocorticoids, secondary to adrenocorticotrophin excess from the pituitary. Common clinical signs and symptoms include weight gain, hypertension, and osteoporosis. Effective treatment of Cushing's disease can normalize biochemical[…][]

  • Hypokalemic Periodic Paralysis

    Due to prolonged repolarization of ventricular Purkinje fibers, a prominent U wave occurs, that is frequently superimposed upon the T wave and therefore produces the appearance[] waves: Prominent Semilunar valve abnormalities Treatment Amiodarone Poor response to classical therapy Cardiac malformation: Occasional Episodic weakness : May segregate in[] Some electrocardiographic (ECG) findings associated with hypokalemia include flattened or inverted T waves, a U wave and ST depression.[]

  • Bartter's Disease

    Abstract The ROMK subtypes of inward-rectifier K( ) channels mediate potassium secretion and regulate NaCl reabsorption in the kidney. Loss-of-function mutations in this pH-sensitive K( ) channel cause Bartter's disease, a familial salt wasting nephropathy. One disease-causing mutation truncates the extreme[…][]

  • Electrolyte Imbalance

    We report a case of hyperkalemia, with concurrent hypocalcemia and hypomagnesemia resulting in (1) peaking of the T wave, (2) a prominent U wave, and (3) prolongation of the[] Widened T wave B. Prominent U wave C. Prolonged QT interval D. Shortened ST segment 68. A. Prominent U waves B. Prolonged PR interval C. Depressed ST segment D.[] Inverted T wave C. Prominent U wave D. Tall peaked T waves 61. A. The client with renal failure B. The client who is taking diuretics C.[]
