Which of the following conditions would most benefit from synchronized cardioversion?

Synchronized cardioversion is a medical procedure used to restore a normal heart rhythm in patients experiencing specific types of arrhythmias that are hemodynamically unstable. In the context of your question, ventricular tachycardia with a pulse is the condition that would most benefit from this procedure.

When a patient is experiencing ventricular tachycardia with a pulse, the heart is beating rapidly but still managing to maintain some level of effective circulation. Synchronized cardioversion allows for the restoration of a normal rhythm without causing harm to the heart's electrical system. The synchronizing aspect is critical as it ensures that the shock is administered at the right moment in the cardiac cycle, specifically during the R wave, to avoid potentially inducing ventricular fibrillation.

The other conditions mentioned do not align as well with the use of synchronized cardioversion. For example, atrial fibrillation, while it can be treated with cardioversion, typically requires different approaches depending on the length of time the patient has been in AFib and their hemodynamic stability. Ventricular fibrillation is a more critical situation that requires immediate defibrillation, which is different from synchronized cardioversion. Lastly, tachycardia is a broader term that encompasses various types of
