What medical condition does "synchronized cardioversion" treat?

• A. Stable bradycardia
• B. Unstable tachyarrhythmias
• C. Atrial fibrillation
• D. Severe hypotension

Answer: (B)

Synchronized cardioversion is a procedure used primarily to treat unstable tachyarrhythmias. This technique involves delivering a controlled electrical shock to the heart that is timed with the heart's natural rhythm, particularly during the R wave of the QRS complex, to restore normal sinus rhythm. Unstable tachyarrhythmias can lead to inadequate cardiac output and hypotension or may even result in more severe complications, which makes timely intervention critical. The indication for synchronized cardioversion leans towards situations where the patient is experiencing significant symptoms due to a fast heart rate or an irregular rhythm that compromises hemodynamic stability. In contrast to conditions like stable bradycardia or atrial fibrillation, synchronized cardioversion targets tachyarrhythmias where immediate intervention is required to stabilize the patient.
