10.6 CCM Inhibit Parameters
By analyzing the train of sensed cardiac events based on their succession and their temporal
order, the OPTIMIZER Smart Mini IPG “decides” for each heartbeat whether to deliver CCM
therapy or not.
10.6.1 CCM Inhibit Cycles
One can program the number of cycles for which CCM therapy delivery will continue to
be inhibited after the initial inhibiting event. With the OPTIMIZER Smart Mini Programmer
application, the number of CCM inhibit cycles can be set to values between 1 and 16.
This means that the delivery of CCM therapy can be inhibited from zero to 15 additional
cycles beyond the initial inhibiting event.
Note: The number of inhibited cycles applies to the most recent detected event that
caused CCM therapy inhibition. If a new inhibiting event is detected during a period of
CCM therapy inhibition, this will trigger a new inhibition period.
10.6.2 Conditions Causing Inhibition
When the OPTIMIZER Smart Mini IPG is in its Active state, certain conditions may cause
CCM therapy delivery to be inhibited. A record of each condition that caused the
inhibition of CCM therapy delivery is stored by the IPG and can be viewed as statistical
data whenever the device is interrogated by the OPTIMIZER Smart Mini Programmer
application. The conditions that cause inhibition of CCM therapy delivery are the
following:
• Short AV: Intervals between an atrial and a ventricular event are considered
“Short AV” if they fall below a programmed threshold. Using the OPTIMIZER
Smart Mini Programmer application, the Short AV threshold can be set to one of
49 possible values between 23 ms and 397 ms. CCM therapy delivery is always
inhibited if a Short AV condition is detected.
Note: This parameter is active only when the OPTIMIZER Smart Mini IPG is in
ODO-LS-CCM mode.
• Long AV: Intervals between an atrial and a ventricular event are considered
“Long AV” if they exceed a programmed threshold. Using the OPTIMIZER Smart
Mini Programmer application, the Long AV threshold can be set to one of 49
possible values between 23 ms and 397 ms. CCM therapy delivery is always
inhibited if a Long AV condition is detected.
Note: This parameter is active only when the OPTIMIZER Smart Mini IPG is in
ODO-LS-CCM mode.
• Atrial Tachycardia (AT): Whenever the atrial tachycardia rate limit is exceeded,
CCM therapy delivery is automatically inhibited. Using the OPTIMIZER Smart
Mini Programmer application, the atrial tachycardia rate limit can be set to one of
51 possible values between 62 bpm and 179 bpm. CCM therapy delivery is
always inhibited when atrial tachycardia rate limit is exceeded.
Note: This parameter is active only when the OPTIMIZER Smart Mini IPG is in
ODO-LS-CCM mode.
• Premature Ventricular Contractions (PVC): A sensed right ventricular event is
considered a PVC if it was preceded by another right ventricular sensing event
without an interposing atrial sense event. CCM therapy delivery is inhibited each
time a PVC condition is detected.
Note: This parameter is active only when the OPTIMIZER Smart Mini IPG is in
ODO-LS-CCM mode.
