Amiodarone induced thyrotoxicosis (AIT) is a form of hyperthyroidism due to treatment with antiarrhythmic drug, amiodarone. Amiodarone induced thyroid dysfunction more commonly results in hypothyroidism , estimated to occur in 6-32% of patients, whereas hyperthyroidism from amiodarone use is estimated at 1-12%. [ 1 ]
Electrolyte imbalance, or water-electrolyte imbalance, is an abnormality in the concentration of electrolytes in the body. Electrolytes play a vital role in maintaining homeostasis in the body. They help to regulate heart and neurological function, fluid balance , oxygen delivery , acid–base balance and much more.
Amiodarone has been used both in the treatment of acute life-threatening arrhythmias as well as the long-term suppression of arrhythmias. [13] Amiodarone is commonly used to treat different types of abnormal heart rhythms, such as atrial arrhythmias (supraventricular arrhythmias) and ventricular arrhythmias.
Acquired problems are usually related to drug toxicity or electrolyte abnormalities, but can occur as a result of myocardial ischemia. Class III anti-arrhythmic drugs such as sotalol and amiodarone prolong the QT interval and may in some circumstances be pro-arrhythmic. Other relatively common drugs including some antibiotics and antihistamines ...
Thyroid disease is a medical condition that affects the function of the thyroid gland.The thyroid gland is located at the front of the neck and produces thyroid hormones [1] that travel through the blood to help regulate many other organs, meaning that it is an endocrine organ.
Amiodarone and lidocaine are anti-arrhythmic medications. Amiodarone is a class III anti-arrhythmic. Amiodarone may be used in cases of ventricular fibrillation, pulseless ventricular tachycardia, and wide complex tachycardia. [110] Lidocaine is a class Ib anti-arrhythmic, also used to manage acute arrhythmias. [111]
Electrolyte and volume homeostasis is a complex mechanism that balances the body's requirements for blood pressure and the main electrolytes sodium and potassium. In general, electrolyte regulation precedes volume regulation. When the volume is severely depleted, however, the body will retain water at the expense of deranging electrolyte levels ...
In addition to correcting the electrolyte abnormalities, magnesium given intravenously has also been shown to be helpful. Magnesium sulfate given as a 2 g IV bolus mixed with D5W can be given over a period of 15 minutes in patients without cardiac arrest [ 8 ] Atrial pacing or administering isoproterenol can normalize the heart rate.
