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
+50% bonus to poison resistance and healing items respectively, and -25% chance for robots to critically hit the player.

Behind the scenes
Cardiac Arrest is a sudden loss of blood flow resulting from the failure of the heart to pump effectively. While a cardiac arrest may be caused by heart attack or heart failure, these are not the same.

Bugs

 * This perk grants -50% critical chance from enemy robots, rather than the listed -25%.
