DOO

(Dual-Chamber Asynchronous Pacing)
In DOO mode, the device paces in the atrium and ventricle(s) at the programmed Base Rate and
AV Delay regardless of intrinsic activity.
CAUTION: DOO mode is primarily intended for temporary use. Long-term use may
result in competitive pacing, which may induce potentially dangerous
tachyarrhythmias.
