AAT and VVT Mode Operation
Pacing occurs at the programmed rate, but a nonrefractory sensed event
triggers an immediate pacing output (rather than inhibiting such output).
Except that pacing outputs occur when events are sensed, the triggered
modes operate identically to the corresponding inhibited modes.
NOTE: Permanently triggered pacing will not occur faster than 300 ms
(200 ppm) from the previous paced event. Temporary programmed
triggered pacing is not limited to 300 ms (200 ppm).
