Which of the following conditions can synchronized cardioversion be used for?

Synchronized cardioversion is a therapeutic procedure used to restore a normal heart rhythm by delivering a controlled electric shock to the heart, timed to coincide with the cardiac cycle. This technique is particularly effective in certain types of tachycardias where the heart's function can be restored without causing further harm.

In cases of atrial fibrillation, synchronized cardioversion can help convert the irregular and often rapid heart rate back to a normal sinus rhythm. This is typically used when the patient is experiencing significant symptoms or when the arrhythmia is not self-limiting.

Similarly, for ventricular tachycardia with a pulse, synchronized cardioversion is indicated to restore effective cardiac function, as it helps eliminate the abnormal electrical activity while preserving a degree of hemodynamic stability. Administering the shock in synchrony with the R wave minimizes the risk of causing harmful arrhythmias, such as ventricular fibrillation.

Atrial flutter is another condition where synchronized cardioversion can be applied effectively, as it similarly aims to correct the rhythm back to a normal sinus pattern. Given these indications, the choice that acknowledges the use of synchronized cardioversion for both atrial fibrillation and ventricular tachycardia with a pulse encompasses significant arrhythmias where
