5. For up to how many cycles does AV Search+ extend its AV delay to search for intrinsic conduction?
8 cycles
1. For what underlying rhythm would you NOT want to program AV Search+ or RYTHMIQ on?
Dependent/CHB
15. What is the marker associated with RYTHMIQ?
RYTHMIQ
10. How many V paced beats need to occur with the AV Search+ algorithm to revert to the device's normal programmed AV delay?
2/10 V paced beats
11.What is the mode and rate RYTHMIQ will operate in when the normal programmed settings are DDDR 60-120?
AAIR 60 with VVI backup 45 ppm
2. What patient population was RYTHMIQ designed for?
Patients with intermittent or exercise-induced AV block
7. What is the marker associated with AV Search+?
Vs-Hy
17. How many slow ventricular beats need to occur for the RYTHMIQ algorithm to switch to the device's secondary mode?
3/11 slow ventricular beats
12. What is RYTHMIQ's primary mode and secondary mode?
Primary mode is AAI(R) with VVI backup, secondary mode is DDD(R)
6. True or False: AV Search+ should be programmed on for patients with second degree Mobitz Type I AV block.
False
16. At what point will you see the RYTHMIQ marker on a recorded episode?
