In brief: Sync or non-sync
It depends whether it is synchronous or asynchronos.
Synchronous is when the shock is delivered on the qrs portion of the heart cycle - it is when the heart depolarises. Asynchronous cardioversion can occur anywhere on the heart cycle.

In brief: Into the QRS
The shock is synchronized to the exact moment that the cardiac muscle is depolarized which corresponds to the qrs complex on the ekg.
