:Supposedly Superman can. But how would a mere mortal stop his heartbeat and live to tell about it? ←[[User:Baseball Bugs|Baseball Bugs]] ^{''[[User talk:Baseball Bugs|What's up, Doc?]]''} [[Special:Contributions/Baseball_Bugs|carrots]]→ 11:02, 25 April 2016 (UTC)

:[http://www.secrets-explained.com/derren-brown/stopping-the-pulse This] and [http://circ.ahajournals.org/content/24/6/1319.full.pdf this] may be relevant. The simple method is to simply hold a rubber ball in the right spot under the arm to cut off the blood flow to the wrists (how most people measure the pulse). Doesn't affect heartrate at all. The harder method involves training the muscles throughout the body to slow blood flow (though this does not actually stop the heart). Does affect heartrate, and could be combined with the rubber ball trick to make one appear totally freaking dead (as long as they're checking the pulse from the wrist). If they had attached monitors somewhere besides his finger tips (I'm not counting a credulous hand as a monitor), they'd've spotted it.
