Re: what happened to the passengers of flight 93? Â« Reply #17 on: May 06, 2011, 05:33:51 pm Â». There are a lot of different theories on here about what happened. I must say that flight 93 might be the the part of 9/11 that I'm the most undecided on.here are a lot of different theories on here about what happened.

Atrial fibrillation and atrial flutter are very fast electrical discharge patterns that make the atria contract very rapidly, with some of the electrical impulses reaching the ventricles and causing them to contract irregularly, faster, and less efficiently than normal.
Atrial capture management. Atrial capture management (ACM) is available when the pacemaker operates in DDD or DDD(R) and the MVP [AAI(R)<=>DDD(R)] modes. If the programmed pacing mode is MVP, the device switches temporarily to DDD(R) mode for the duration of the pacing threshold search.
