5.2.4 ‘A’ Sens (mV) (Atrium Sensitivity )
This knob is used to set Atrium sensitivity (mV) values. It
allows continuous adjustment of the Sensitivity from 0.4 to
10 mV.
Description of Atrium Sensitivity: Sensitivity is the ability
of the pacemaker to see intrinsic cardiac events (P Wave).
5.2.5 Mode
This knob is used to set desired Mode. AOO, AAI, DOO,
DVI, DDD, VDD, VVI , VOO and Urgent.
Description of Mode: This parameter defines the
functionality of Pacemaker. It is defined by the 3 position
NBG code as below :--
I II III
Chamber(s)
Paced
Chamber(s)
Sensed
Mode(s) of
Response
O - None
A - Atrium
V - Ventricle
D - Dual (A+V)
O - None
A - Atrium
V - Ventricle
D - Dual (A+V)
O - None
T - Triggered
I - Inhibited
D - Dual (T + I)
S = Single (A/ V) S = Single (A/ V)
5.2.6 Refractory Period (A & V)
The Refractory period is the interval during which a sensed
event does not affect pacing timing.
The Ventrical
refractory period is fixed at appox. 250 ms. Knob is used
to set Atrial refractory period (ms). It allows continuous
adjustment of A Ref period from 150 to 500 ms. This is
PVARP (Post ventricle Atrial refractory period) for dual
chamber modes.
