Which of the following arrhythmias can synchronized cardioversion be used to treat?

• A. Atrial fibrillation
• B. Asystole
• C. Ventricular fibrillation
• D. Sinus bradycardia

Answer: (A)

Verified step by step guidance

1. Understand the concept of synchronized cardioversion: It is a medical procedure used to restore a normal heart rhythm in cases of certain types of arrhythmias. It involves delivering a controlled electric shock to the heart at a specific point in the cardiac cycle.
2. Identify the types of arrhythmias: The problem lists four arrhythmias: Atrial fibrillation, Asystole, Ventricular fibrillation, and Sinus bradycardia.
3. Evaluate each arrhythmia for treatment with synchronized cardioversion: Atrial fibrillation is a common arrhythmia that can be treated with synchronized cardioversion. Asystole, which is a flatline or absence of heart activity, is not treated with cardioversion. Ventricular fibrillation requires defibrillation, not synchronized cardioversion. Sinus bradycardia is typically treated with medications or a pacemaker, not cardioversion.
4. Focus on Atrial fibrillation: Since synchronized cardioversion is specifically used to treat atrial fibrillation among the options provided, it is important to understand that this procedure is effective in converting atrial fibrillation to a normal sinus rhythm.
5. Conclude with the correct application: Based on the evaluation, synchronized cardioversion is used to treat atrial fibrillation, making it the correct answer among the options provided.
