What cardiac condition is indicated for the administration of amiodarone?

• A. Bradycardia
• B. Heart block
• C. Dysrhythmias - Tachycardia
• D. Myocardial infarction

Answer: (C)

Amiodarone is an antiarrhythmic medication that is primarily indicated for the treatment of dysrhythmias, especially those associated with tachycardia. This medication works by prolonging the action potential and refractory period in myocardial tissue, which helps stabilize heart rhythm and restore normal heart function. It is commonly used in emergencies for conditions such as ventricular tachycardia and ventricular fibrillation, where rapid heartbeats can compromise cardiac output and lead to serious complications. In contrast, bradycardia generally requires medications that increase heart rate, whereas amiodarone is not utilized in heart block situations where there is a complete disruption in conduction. Myocardial infarction may involve the use of amiodarone in specific cases where tachyarrhythmias are present, but it is not the primary indication compared to direct treatment for dysrhythmias.
