What will be administered for A-fib/A-flutter management if synchronized cardioversion is indicated?

The management of atrial fibrillation (A-fib) and atrial flutter (A-flutter) often requires the use of synchronized cardioversion when patients are symptomatic or when unstable arrhythmias are present. Synchronized cardioversion can be performed using specific energy levels, starting at a lower setting and increasing as necessary. The usual recommended energy levels for synchronized cardioversion are 70 joules, 120 joules, 150 joules, and up to 200 joules, depending on the patient's condition and response.

Administering synchronized cardioversion effectively addresses the abnormal electrical activity in the heart by delivering an electrical shock at a moment that aligns with the R wave of the QRS complex. This timing is critical, as it prevents the shock from inducing further arrhythmias and allows for a successful return to a normal sinus rhythm.

In contrast, other options provided do not directly relate to the immediate management of A-fib or A-flutter in the context of synchronized cardioversion. For instance, administering normal saline (NS IV) is not a specific treatment for rhythm stabilization, though it could potentially play a role in overall patient fluid management. Adenosine is more appropriate for terminating supraventricular tachycard
