Rate Drop Response

Question 1

What is the purpose of the Rate Drop Response feature?

Answer 1

To prevent syncopal or symptomatic episodes associated with sudden drops in heart rate

Question 2

Which feature is meant to prevent syncopal or symptomatic episodes associated with sudden drops in heart rates?

Answer 2

Rate drop response

Question 3

What are the 2 types of rate drop responses?

Answer 3

Low Rate Detect and Drop Detect

Question 4

How does the Low Rate Detect RDR feature work?

Answer 4

Paces at a programmable rate and time once the HR falls to to or below a programmed lower rate for a programmed amount of beats

Question 5

How does the Drop Detect RDR feature work?

Answer 5

Paces at at a programmed rate and time if the device is programmed to “drop” or “both” and the below occurs:
-> drop in ventricular rate >/= to the programmed “drop size” for 2
consecutive beats
-> ventricular rate drops to or below the programmed Drop rate for
2 consecutive beats
-> the 2 consecutive beats MUST is within the programmed
detection window

Question 6

Can Rate Drop Response work in a rate responsive mode?

Answer 6

No, the device cannot be in a rate responsive mode
-> device cannot look for both a drop in rate and drive the rate at
the same time

Question 7

What does PVARP need to be programmed to if the MD wants to rate drop response?

Answer 7

Needs to be programmed to a fixed value, cannot be “Auto”

Question 8

Why must Mode Switch be turned “OFF” while Rate Drop Response is on?

Answer 8

Because the device mode switches into a rate responsive mode
