Capture Management Flashcards
What happens if Atrial Capture Management cannot conduct a threshold test at the programmed time?
it will try again after 30 mins
Does ACM work while the device is in a Mode Switch episode?
No, waits until the end of episode and for the device to return to normal programming
What is the criteria for ACM to use the Atrial Chamber Reset method?
- device needs to see 8 consecutive AS events and a HR < 87bpm
How does the Atrial Chamber Reset (ACR) algorithm determine capture vs non-capture when conducting the daily threshold test?
- non-capture = an AR following the test pace
- capture = no AR following the test pace
What is the criteria for ACM to use the Atrial Ventricular Conduction (AVC) method?
- need 8 consecutive AP-VS and stable 1:1 AV conduction
How does the Atrial Ventricular Conduction (AVC) algorithm determine capture vs non-capture when conducting the daily threshold test?
- non-capture = no VS following the test pace
- capture = a VS following the test pace
At what voltage will ACM issue a High Threshold Warning?
2.5V
When does Ventricular Capture Management (VCM) conduct the first threshold test?
- 12hrs after implant detection is complete in PM
- when detection is turned on in ICD’s
What are the requirements for Ventricular Capture Management to conduct a threshold test when the USR and UTR are greater than or equal to 135bpm?
looks a 8 consecutive V-V intervals
- needs 6/8 to be < 100bpm
What are the requirements for Ventricular Capture Management to conduct a threshold test when the USR and UTR are between 125-135bpm?
looks a 8 consecutive V-V intervals
- needs 6/8 to be < 95 bpm
What are the requirements for Ventricular Capture Management to conduct a threshold test when the USR and UTR are < 125 bpm?
looks a 8 consecutive V-V intervals
- needs 6/8 to be < 90 bpm
How many V-V intervals does VCM measure when checking for stable conduction prior to performing a threshold test?
8 consecutive V-V intervals
