this is true for all cases. You always remove clothing from the patient's chest and place the AED pads. You would only remove the victim from water if they were in water in the first place (and quickly wipe the check dry). you would only shave the victim's hairy chest if you only have one set of pads, or when you try to apply the pads the first time, the AED tells you to make sure they are correct. And you would only find the victim's implanted pacemaker if you see a scar. You can still shock someone with a pacemaker, you just can't put the pads on top of the device.
