Hyperthyroidism arrhythmia

Anxiety Disorder Due to a General Medical Condition with Panic Attacks. Many medical illnesses are associated with anxiety and even recurrent panic attacks. These include endocrine disorders, such as hyperthyroidism, hyperparathyroidism, hypoglycemia, and pheochromocytomas, inner ear (vestibular) dysfunction, seizure disorders, and cardiac (heart) disorders such as supraventricular tachycardia, mitral valve prolapse, and various arrhythmias, and carcinoid. A general physical examination, routine laboratory studies including electrolytes and... 

Hyperthyroidism - Hyperthyroidism usually poses a greater hazard to the patient than hypothyroidism because of the possibility of arrhythmia breakthrough or aggravation. If any new signs of arrhythmia appear, consider the possibility of hyperthyroidism. Aggressive medical treatment is indicated, including, dose reduction or withdrawal of amiodarone. 

Cardiovascular disorders Use with extreme caution in patients with cardiovascular disorders because of the possibility of conduction defects, arrhythmias, CHF, sinus tachycardia. Ml, strokes, and tachycardia. These patients require cardiac surveillance at all dose levels of the drug. In high doses, TCAs may produce arrhythmias, sinus tachycardia, conduction defects, and prolonged conduction time. Tachycardia and postural hypotension may occur more frequently with protriptyline. Hyperthyroid patients Hyperthyroid patients or those receiving thyroid medication require close supervision because of the possibility of cardiovascular toxicity, including arrhythmias.

Adverse effects are usually due to excessive doses (which may occur if the initial increase in metabolism is too rapid) and correspond to symptoms of hyperthyroidism, but they usually disappear after dose reduction or withdrawal of treatment. The most common adverse effects affect the following system as Heart arrhythmias, anginal pain, Central nervous system headache, hyperactivity, sweating, tremor, heat intolerance, Gastrointestinal tract diarrhoea, excessive weight loss, vomiting, Musculoskeletal system muscle cramps, muscle weakness. 

The most common adverse effects (i.e., symptoms of hyperthyroidism) are the result of a drug overdose they include cardiac palpitation and arrhythmias, tachycardia, weight loss, tremor, headache, insomnia, and heat intolerance. Symptoms subside if medication is withheld for several days.

The most serious complication of hyperthyroidism is thyroid storm (thyrotoxic crisis). This is an acute exacerbation of hyperthyroidism with marked tachycardia, fever, mental status changes and haemodynamic collapse. It is usually precipitated by acute illness, trauma, parturition or surgery, especially of the thyroid gland. The mortality rate is 20-30%, even with aggressive treatment, due to cardiac failure, arrhythmias or hyperthermia.

Amiodarone blocks the peripheral conversion of thyroxine (T4 ) to triiodothyronine (T3). It is also a potential source of large amounts of inorganic iodine. Amiodarone may result in hypothyroidism or hyperthyroidism. Thyroid function should be evaluated before initiating treatment and should be monitored periodically. Because effects have been described in virtually every organ system, amiodarone treatment should be reevaluated whenever new symptoms develop in a patient, including arrhythmia aggravation.
