7.1.5 Pacing Modes with Triggered Response
Pacing modes with triggered response correspond to their
respective demand pacing modes, except that a sensed event
will not inhibit but will rather trigger a pacing pulse,
simultaneously with the sensed event, into the same chamber
where sensing has occurred. The demand and corresponding
triggered pacing modes are:
Demand: DDD VVI AAI
Triggered: DDT VVT AAT
The triggered pacing mode fixes the AV delay to 180 ms and
does not provide a safety AV delay.
Pacing modes with triggered response may be indicated in the
presence of interference signals to prevent inappropriate pulse
inhibition. They may also have diagnostic application for ECG
identification of sense events as an alternative to marker signals.
Triggered pacing may also be used for hemodynamic as well as
electrophysiologic studies and for termination of tachycardias by
non-invasive triggering of pulse generator pulses with chest wall
stimuli generated by an external pulse generator.
