400 Possible Causes for Iodine-induced Hyperthyroidism, Preexcitation Syndrome, Short PR 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[intechopen.com] It neutralizes hyperthyroidism within 6 to 18 weeks.[ihealthblogger.com] hyperthyroidism.[thyroid.about.com]

  • Hypertrophic Cardiomyopathy

    PR interval ( First-degree (PR 0.21 s, not shortening with hyperventilation), second-degree, or third-degree atrioventricular block To assess whether the changing pattern[doi.org] Incidence of preexcitation phenomenon of the Wolff-Parkinson-White syndrome type, which may cause palpitations, is increased. Bundle branch block is common.[merckmanuals.com] interval of 120 to 180 ms, but when the PR interval is shorter, a very short AV delay (50 to 60 ms) is frequently required for complete ventricular capture. 183 This often[doi.org]

  • Wolff-Parkinson-White Syndrome

    Wolff-Parkinson-White (WPW) syndrome is defined as the presence of an accessory atrioventricular pathway which is manifested as delta waves and short PR interval on electrocardiography[ncbi.nlm.nih.gov] It seems reasonable, therefore, to revisit the clinical and electrophysiologic role of preexcitation syndromes in current practice.[ncbi.nlm.nih.gov] Electrocardiography (ECG) of patients with WPW syndrome portrays a short PR interval and a wide QRS interval with a delta wave.[ncbi.nlm.nih.gov]

  • Preexcitation Syndrome

    PR interval (usually 0.1 second or less; occasionally normal) together with a prolonged QRS complex with a slurred initial component (delta wave).[medical-dictionary.thefreedictionary.com] The main tool used to establish the preexcitation syndrome diagnosis is the 12-lead electrocardiogram.[symptoma.com] The classic electrocardiogram in Wolff-Parkinson-White (WPW) syndrome is characterized by a short PR interval and prolonged QRS duration in the presence of sinus rhythm with[ncbi.nlm.nih.gov]

    It suggests that HSG also leads to excessive iodine absorption, which induces secondary hyperthyroidism.[ncbi.nlm.nih.gov] Cholestyramine is an effective additional treatment for hyperthyroidism and may be an effective treatment for refractory iodine-induced hyperthyroidism.[ncbi.nlm.nih.gov] […] to its development. [ 2 ] While too much iodine can induce hyperthyroidism, iodine can, oddly enough, also be the solution.[globalhealingcenter.com]
