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 ]
Amiodarone is commonly used to treat different types of abnormal heart rhythms, such as atrial arrhythmias (supraventricular arrhythmias) and ventricular arrhythmias. [ 13 ] Atrial arrhythmias and supraventricular arrhythmias are terms often used interchangeably to refer to abnormal heart rhythms originating from the upper chambers of the heart ...
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.
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 ...
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.
Women are more likely to survive cardiac arrest and leave the hospital than men. [147] Hypoxic ischemic brain injury is a concerning outcome for people suffering a cardiac arrest. [ 148 ] Most improvements in cognition occur during the first three months following cardiac arrest, with some individuals reporting improvement up to one year post ...
In severe or acute hypoosmolar hyponatremia, swelling of brain cells causes various neurological abnormalities, which in severe or acute cases can result in convulsions, coma, and death. The symptoms of chronic syndrome of inappropriate antidiuresis are more vague, and may include cognitive impairment, gait abnormalities, or osteoporosis. [2]
A basic metabolic panel including calcium is sometimes colloquially referred to as a "CHEM-8". Calcium, as an alkaline earth metal, is also an electrolyte, but abnormalities are more commonly associated with malnutrition, osteoporosis, or malignancy, especially of the thyroid. [citation needed]
