Your heart is back in your body, but some advanced technologies remain: You are more resistant to poison (50%) and robots are only somewhat confused by you (25% less likely to score a critical hit) now. But on the bright side, healing items (chems) are even more effective!Fallout: New Vegas description

Cardiac Arrest is a special perk in the Fallout: New Vegas add-on Old World Blues.


The Courier must convince the Brain Tank to unite the Courier's brain with their body or convince it to come back to The Sink. After that, one can have their heart reinserted into their body. This perk replaces Heartless.


Poison Resistance +50%. Critical Chance -25% for Robots against the player. Consuming Stimpaks or Super Stimpaks grants an additional +15 HP. Consuming any healing item in the table below grants an additional +7 HP.

  • Grants the full 85% resistance to poison when combined with 8 Endurance, the maximum achievable in derived statistics. Of course, this is still outclassed by Heartless's poison immunity.
  • Cardiac Arrest shares the same Vault boy image as Heartless.
