Not long: Survival from cardiac arrest is determined by many things, and time is certainly an important one. However, how well the body is oxygenated and perfused during the arrest (say, by cpr) as well as body temperature all play a role. In your question, you imply there is no oxygen - so the answer is mere minutes.
