I know that unsynch cardioversion or defib is what is used for pulseless vtach, but I wondered if you are able to synch, could that be preferrable in some cases? For example, pt with some BP, just not detectable with cuff. Other than time (assuming you can synch), wouldn't it be more beneficial to shock not on T? Or, is it that the arrhtymia is so disorganized, that it doesn't matter, and just shock to restart everything.

Blood pressure that is not detectable by a cuff is functionally none - just like CPR when the heart rate (even with a pulse) is under 30. There's no guarantee that synced cardioversion will work, so, if there is no detectable pulse, you go right to the end game.
