Conditional Cans
Does MRI mode automatically turn off tachy therapies in an ICD?
What is yes
Generally, how fast do you want to program a pt's rate above their intrinsic?
What is 10 bpms above intrinsic
What is important to do before making programming changes to a nonconditional can to ensure previous settings are the same?
What is saving a set
What mode is appropriate for a pt in AF w/ V rate 50s with a dual chamber device?
What is VOO
What pacing percentages do we use to determine if the pt needs pacing support?
What is >5%
How do you turn on Boston Scientific's MRI mode?
What is, in the tachy button at the top, MRI mode is available for programming
A pt has a dual chamber ICD with high degree AV block. Given their sinus rate is 75 bpm, how should they be programmed?
What is in DOO at 85 bpm with tachy therapies off
If a patient has a nonconditional system and is dependent with no escape rhythm, what is required for the duration of the MRI scan?
What is the fellow sitting during the MRI
If a patient has sick sinus syndrome with intact AV conduction, what should they be programmed?
What is AOO
What polarity do the leads need to be programmed in to continue with an MRI?
What is Bipolar
How do you turn on MRI mode in a Biotronik device?
What is in the parameters
If a patient has a single chamber ICD with RV pacing less than 3%, how should it be programmed?
What is OVO with tachy therapies off
What can make a system nonconditional?
What is ...
- nonconditional, abandoned, fractured, or epicardial wires
- nonconditional cans
What should the lead outputs be changed to when hard programming for MRI?
What is 5.0V @ 1.0ms for RA and RV leads. No changes necessary for LV lead because of possible PNS
What should be done before and after an MRI to ensure the leads are stable with no new issues?
What is sensing, impedance, and threshold testing
What does MRI mode do to the LV lead in CRT-Ds?
What is LV off (RV only) or leave LV on (BIVP) at its permanently programmed output **Company and Model dependent**
-MDT: RN only or BIVP is model dependent, LV vector cannot include RVcoil
- BSC, Bio, ABT: Can choose RV only or BIV pacing
How should you program a pt in AS/VS @ 70 bpm with bigeminal PVCs? Atrial and ventricular pacing are 55%.
What is program in DOO at 10 beats above, if this doesn't overdrive the PVCs, then go 10 more above
For programming a nonconditional Boston can, there is no MRI mode available or ability to save a set. What is the next best thing to do and how do you program this?
What is electrocautery mode; you must hard program the appropriate LRL and then turn on electrocautery mode. To end session while keeping this active, turn the programmer off
How should you program a CRTD for a patient in AF with a V escape at 35 bpm?
What is VOO (70-90 bpm) with tachy therapies off
How soon after implant can a patient be considered MRI conditional?
What is 6 weeks post implant
- Abbott is the exception, MRI conditional immediately
How do you save your PDF for the pre-MRI docket for each company?
What is...
- Medtronic, Abbott, Boston: save like normal before MRI programming
- Biotronik: after programming, end session. Export PDF to USB on new programmer
If a test value is out of range in a conditional system, how would you program the device?
MRI mode may lock out, leaving you to hard program MRI settings
If your patient is nonconditional, has a history of dependency, but is not dependent today, what should you do?
What is continue with the MRI. Pt does not need the fellow to sit
If a pt is in AF with RVR above 120 bpm, what mode should you program the pt in? Regardless of pacing percentages
What is OVO
What is our new definition for determining if a patient is pacer dependent?
What is no escape rhythm for 10 seconds at VVI 30
