Cardiac Arrest

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

Obtaining
The Courier must convince their brain to return to their body or convince it to come back to The Sink. After, one can have their heart reinserted into their body. This perk replaces Heartless.

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

Behind the scenes
The real-life term "cardiac arrest" refers to a sudden loss of blood flow resulting from the failure of the heart to pump effectively. While a cardiac arrest may be caused by myocardial infarction (heart attack) or congestive heart failure, these are not the same.

Bugs

 * This perk grants -50% critical chance from enemy robots, rather than the listed -25%.
 * The Sink Auto-Doc message for this perk erroneously states "healing items (chems) are twice as effective (+50%)".
