79 Possible Causes for Prominent U Wave

  • Sinus Bradycardia

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

  • Hypokalemia

    prominent U waves require hospital admission.[physio-pedia.com] Weak pulses (irregular and thread) Orthostatic Hypotension Depression ST, flat or inverted T wave and prominent u-wave Shallow respirations with diminished breath sounds….[registerednursern.com] 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[physio-pedia.com]

  • Digoxin

    The terminal positive deflection may be peaked, or have a prominent U wave superimposed upon it.[lifeinthefastlane.com] Prominent U waves . Peaking of the terminal portion of the T waves. J point depression (usually in leads with tall R waves).[lifeinthefastlane.com] This is usually seen in leads with a dominant R wave (e.g. V4-6). The first part of the T wave is typically continuous with the depressed ST segment.[lifeinthefastlane.com]

  • 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[flipper.diff.org] Prolongation of the PR and QT intervals and T-wave flattening are associated with prominent U-waves.[hkpp.org] waves: Prominent Semilunar valve abnormalities Treatment Amiodarone Poor response to classical therapy Cardiac malformation: Occasional Episodic weakness : May segregate in[neuromuscular.wustl.edu]

  • Cardiodysrhythmic Potassium-Sensitive Periodic Paralysis

    U waves in V1–V4 at rest.[innovationsincrm.com] Prominent U waves in the anterior precordial leads are common in ATS. 11 Although U waves can be observed in normal individuals at low heart rates or in hypokalemic states[cogprints.org] waves: Prominent Semilunar valve abnormalities Treatment Amiodarone Poor response to classical therapy Cardiac malformation: Occasional Episodic weakness : May segregate in[neuromuscular.wustl.edu]

  • Myxedema

    Hypothyroidism is a common medical problem easily treated when diagnosed but requiring regular follow-up and patient medication compliance. At times, this diagnosis can go untreated resulting in the development of severe consequences such as Myxedema Coma. Of all the clinical symptoms, cardiovascular manifestations[…][ncbi.nlm.nih.gov]
