Basically synchronized cardioversion is shocking at a particular point in the sinus rhythm. It is used for supraventricular tachycardia and atrial fibrillation / flutter. These are rhythms the AED is not programmed to shock; recall AED shocks for VF and VT. See the related link.
From the related link, Synchronized Cardioversion is: --A controlled form of defibrillation for patients who still have organized cardiac activity with a pulse.

Defibrillation also known as cardioversion.
A synchronized cardioversion shock is delivered a few milliseconds after the R wave on the EKG. The R wave represents ventricular depolarization, which is followed by mechanical contraction of the ventricle. Therefore, it can be seen that a synchronized shock will occur during ventricular contraction, or during ventricular systole, to completely depolarize the myocardium and try to restore a normal rhythm.
Cardioversion is used to stop this abnormal beating so that the heart can begin normal rhythm and pump more efficiently.
in about 50% of cases, the heart prefers its abnormal rhythm and reverts to it within one year, despite cardioversion.
Cardioversion
Synchronized
During the process of cardioversion, an electrical shock is delivered to the heart in an attempt to change an irregular heart beat rhythm into a normal one.
Treating the underlying cause of the arrhythmia, such as correcting electrolyte imbalances, reducing stress, or using medication to regulate heart rhythm, can help convert arrhythmia back to normal sinus rhythm. In some cases, cardioversion or ablation procedures may be necessary to restore normal heart rhythm.
Healthcare providers may also try to correct the heart rhythm with medication or recommend a lifestyle change before trying cardioversion.
