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 ...
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.
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]
Additional factors that may contribute to cardiac arrest include major blood loss, lack of oxygen, electrolyte disturbance (such as very low potassium), electrical injury, and intense physical exercise. [16] Cardiac arrest is diagnosed by the inability to find a pulse in an unresponsive patient.
Blood tests may be done to rule out specific underlying causes such as hyperthyroidism, pheochromocytomas, or electrolyte abnormalities. [4] A normal resting heart rate is 60 to 100 beats per minute. A resting heart rate of more than 100 beats per minute is defined as a tachycardia.
