22 Possible Causes for Cardiomyopathy, Iodine-induced Hyperthyroidism, Prolonged QT Interval

  • Graves Disease

    Conversely in some patients (iodine induced hyperthyroidism, drugs like amiodarone and propronolol which block the conversion of T 4 to T 3 ), only TT 4 or FT 4 is elevated[] […] disease is an autoimmune disease, which can manifest with a variety of extrathyroidal clinical syndromes like ophthalmopathy, pretibial myxedema (dermopathy), acropathy, cardiomyopathy[] It neutralizes hyperthyroidism within 6 to 18 weeks.[]

  • Thyrotoxic Heart Disease

    It is contraindicated in iodine-induced hyperthyroidism and in patients in whom radioiodine treatment is planned (it causes a reduction of iodine uptake for 6 months).[] Patients presenting with heart failure and dilated cardiomyopathy may have thyrotoxicosis as the underlying cause.[] PR interval Shortened QT interval Atrial fibrillation: The prevalence of AF in hyperthyroidism is 7-8 %, which increases with age to a peak of 15 % in persons 70 years or[]

  • Hypokalemia

    Additionally, a few case reports have noted a risk for hypokalemia with the use of iodinated contrast. 11 In these cases, iodinated contrast-induced hyperthyroidism leads[] 4351 4400 番を表示 (全 8148 件) 英文 和文 略語 hypertrophic nonobstructive cardiomyopathy 肥大型非閉塞性心筋症 hypertrophic obstructive cardiomyopathy 肥大型閉塞性心筋症 HOCM hypertrophic pyloric stenosis[] QT interval may be seen, which is actually the QU interval with an absent T wave. 1 Severe hypokalemia can also cause a variety of tachyarrhythmias, including ventricular[]

  • Cardiodysrhythmic Potassium-Sensitive Periodic Paralysis

    , [1] and amiodarone -induced hyperthyroidism. [2] Mechanism [ edit ] Na /K -ATPase maintains the normal gradients of sodium and potassium between cells and extracellular[] A family with Andersen-Tawil syndrome and dilated cardiomyopathy.[] Lists of medications associated with prolongation of the QT interval can be found online.[]

  • Hypothyroidism

    Monitoring of prescription rates of thioamides can be a further tool to detect iodine-induced hyperthyroidism in the general population.[] Overt hypothyroidism may exacerbate underlying cardiac disease, but cardiomyopathy severe enough to cause heart failure is rare ( Kahaly 2005 ).[] […] of QT interval with risk of malignant cardiac arrhythmias such as torsade de pointes) Inhibitor in citrus fruits The flavonoid naringin, contained in citrus fruits (especially[]

  • Dilated Cardiomyopathy 1R

    Amiodarone-induced thyrotoxicosis (AIT) is present in two forms: type 1 AIT, or iodine-induced hyperthyroidism, and type 2 AIT, or destructive thyroiditis.[] CARDIOMYOPATHY, DILATED, 1V CARDIOMYOPATHY, DILATED, 1W CARDIOMYOPATHY, DILATED, 1Y CARDIOMYOPATHY, DILATED, 1Z CARDIOMYOPATHY, DILATED, 2A CARDIOMYOPATHY, DILATED, 2B CARDIOMYOPATHY[] Electrocardiographic (ECG) changes include nonspecific ST segment and T wave changes, decreased QRS voltage, prolonged QT interval, and sinus tachycardia.[]

  • Apathetic Thyrotoxicosis with Thyrotoxic Crisis

  • T3 Thyrotoxicosis

    Iodine-induced hyperthyroidism Some of the causes that regress hyperthyroidism (or worsen thyroid control), despite controlling it during pregnancy include: Stimulation of[] (familial) (idiopathic) I42.9 ICD-10-CM Diagnosis Code I42.9 Cardiomyopathy, unspecified 2016 2017 2018 2019 Billable/Specific Code Applicable To Cardiomyopathy (primary)[] ECG changes include a prolongation of the QT interval that predisposes to ventricular irritability [ 32 ]. There is prolongation of the isovolumic diastolic relaxation.[]

  • Amiodarone

    Amiodarone -associated hyperthyroidism, or amiodarone -induced thyrotoxicosis (AIT) is generally sub-divided into two types, an iodine-induced hyperthyroid condition (Type[] We determined the functional consequences and pharmacologic responses of a novel SCN5A mutation associated with an arrhythmia-associated cardiomyopathy.[] The QT interval was prolonged from day 3; TpTe was prolonged from day 7 to day 14; QTp was prolonged from day 1 to day 20.[]

  • Thyrotoxic Periodic Paralysis

    To report a case of iodine-induced (Jod-Basedow) hyperthyroidism leading to thyrotoxic periodic paralysis (TPP).[] Flecainide has been shown to be successful in treating bidirectional ventricular tachycardia, ventricular ectopy, and tachycardia-induced cardiomyopathy. [20][] Our patient was found to have an extremely low serum potassium concentration, as well as an electrocardiogram that revealed a prolonged QT interval and right bundle branch[]
