Sensitivity; Pacing; Sensing; Ventricular Support Rate (Voo) - Abbott Merlin PSA EX3100 Help Manual

Sensitivity

The Sensitivity parameter determines the threshold above which the device responds to intrinsic
cardiac events.

Parameter Settings and Availability (page 34)

V. Pacing
The Ventricular Pacing parameter determines which ventricles receive stimulation and the order
in which the stimulation is applied. When you select the LV—>RV or RV—>LV settings, you can
also set the Interventricular Delay parameter.

Parameter Settings and Availability (page 34)

V. Sensing
The V. Sensing parameter determines the channel in which ventricular sensing occurs when the
selected device implant type is CRT-D or CRT-P.
When the V. Pacing parameter is changed, the V. Sensing parameter is autoprogrammed to
match the chamber selected for V. Pacing.

CAUTION: For CRT devices, if only one ventricular channel is connected to the
Merlin™ PSA, ensure that the Ventricular Sensing button on the Lead Tests window
corresponds to the connected channel. Failure to do so will result in asynchronous

pacing.

Ventricular Support Rate (VOO)

The Ventricular Support Rate (VOO) parameter determines the stimulation rate applied to the
ventricle during atrial Burst Pacing.
