Table 28: Atrial Sensitivity Settings
Setting Definition for Use
Standard This setting is recommended for all
patients with a functioning atrial lead.
Inactive This setting deactivates the atrial channel
for sensing, EGM telemetry and Holter
recording and is typically used when no
atrial lead is implanted.
Typically, the upper threshold is reset with each sensed P-wave,
but in order to ensure that pacing does not occur during an
episode of AF/VF, the ASC behaves differently with paced
events. Each paced event is followed by a paced refractory
period after which the atrial threshold is set to the minimum
programmed value.
2.3.4 Minimum Atrial Threshold
This parameter limits the minimum sensitivity of the ICD/CRT-D to
a programmable value. Nominally, the minimum threshold is set
to 0.4 mV, but it can be adjusted from 0.2 to 2.0 mV.
2.3.5 Left Ventricular Sensitivity Settings
HF versions only
The primary option for setting the sensitivity of the left ventricular
input stage is “Standard”. When LV sensing is active, the
sensitivity is set to “Standard” for most patients, which is designed
to adapt the parameters of the input stage to various signal
conditions. The available settings are described in Table 29
.
