Term
Increasing the sudden onset delta will make adiagnosis of VT more or less likely?
Definition
Less
Term
If you lose telemetry after DC Fibber is induced and the therapy method is auotmatic, will the device still deliver tx?
Definition
Yes
Term
In fortify, ATP can be programmed in all 3 zones
Definition
Yes
Term
Episodal pacing automatically begins
Definition
After 3 binned tach or fib
Term
Which IEGM shows you what the ICD sees for sensing and detection of VF?
Definition
V sense amp
Term
When is readaptive useful in a pt
Definition
When ATP is programmed on and the VT changes cycle length (up or down)
Term
DC fibber will most likely induce
Definition
VF
Term
When a VS beat is designated "T" what does that mean
Definition
Tach interval binned
Term
When a "T" beat is designated "x" what does that mean
Definition
Tach interval binned, no morphology match
Term
If the shocking impedance is high with a fixed tilt of 65%, your pulse width would be longer than with a lower impedance?
Definition
yes
Term
SVT discriminators can be used in all zones
Definition
no
Term
VSS is programmable on/off during episodal pacing
Definition
no
Term
DC fibber delivers direct current through the HV electrodes
Definition
yes
Term
Interval stability is beneficial in discriminating
Definition
AF w/RVR from VT
Term
Data from clinical studies showed DC fibber worked w/o adjusting any parameters 96.4% of the time
Definition
yes
Term
When a tach diagnosis is made and the tx is ATP, how does the device determine the rate of the ATP to be delivered?
Definition
the last interval average is used to determine the tach cycle length
Term
What type of complex should be stored for the morphology template?
Definition
Sinus
Term
What svt discriminators are available in the V>A rate branch?
Definition
None
Term
Morphology is beneficial in differentiating ST from VT
Definition
yes
Term
Why would there be a dash under an interval (and no T, VS, VF)?
Definition
either the CL or IA was the VS while the other was VT or VF
Term
placing a magnet on a HV device pwill force asynchronous pacing and inhibit tachy/fib tx
Definition
false, will inhibit tachy/fib tx only
Term
Readaptive refers to
Definition
recalculation of the BCL w/changes in the Tachy cycle length
Term
Ramp refers to
Definition
the successive decreasing of the cycle length intervals within a burst
Term
If you have a high DFT, what is the first thing to try to lower it?
Definition
tune the waveform
Term
increasing the delta for interval stability will make the call of VT more likely
Definition
1
Term
during post shock pacing, when does the post shock pacing mode begin?
Definition
upon return to sinus tach
