PPM EGM & Troubleshooting

Question 1

When should RAAV be turned on?

Question 2

What considerations should be taken when programming maximum offset for RAAV?

Question 3

When should sleep rate be turned on?

Question 4

How is an inappropriate Ap % determined?

Question 5

What methods can be used to reduce a high Ap %?

Question 6

Aside from thresholds and impedance, what other indicators can suggest compromised lead integrity?

Answer 6

Short VV intervals
High PVC counters
Episodes

Question 7

True or false

Intervals and occurance for T wave oversensing are consistent.

Answer 7

True

TWOS should demonstrate regular intervals and occur continuously.

*They should not be affected by position or movement

Question 8

If bipolar pacing configuration is compromised, why is it important to also consider programming sensing to unipolar.

Answer 8

If pacing is compromised and there is suspicion of a fracture, oversensing or under sensing could also occur on the bipolar lead. To mitigate this in advance programme sensing to unipolar and vice versa.

Question 9

When programming a unipolar sensing configuration, how much more of a safety margin should be programmed on the sensitivity and why?

Answer 9

4x safety margin
To mitigate risk of oversensing myopotentials
