Pacing, Mode, and V. Pacing Parameter Autoprogramming
The Pacing, Mode, and V. Pacing parameters are linked, so that a change to one parameter results in
automatic changes to the other two. For example, enabling Pacing in the atrial channel (when
ventricular pacing is off) changes the Mode setting from ODO to AAI. Similarly, changing the Mode
from AAI to DDD will turn on Pacing in the ventricular channel (or in a CRT device, the ventricular
channels designated by the V. Pacing parameter). In CRT devices. changing the V. Pacing setting from
RV Only to Simultaneous enables pacing in the LV channel (if the Mode parameter is set to DDD or
VVI).
The following table above shows how the Merlin PSA is programmed for all combinations of the
Pacing, V. Pacing, and Mode parameters.

CAUTION
Leaving the atrial connector disconnected when the Merlin PSA is in
DDD or VDD modes may result in the unit sensing external noise
and increasing the ventricular pacing rate to the Max Track Rate.
