PBL-STOP testing

Question 1

What values can be changed to properly perform the sensing test?

Answer 1

• AV Delay

- Lower Rate limit

Question 2

During a sensing test, what is done for a patient that is AS-VP?

Answer 2

• increase AV Delay to allow intrinsic ventricular conduction to occur
• do not change the lower rate since Atrial sensing is occurring

Question 3

During a sensing test, what is done for a patient that is AS-VS?

Answer 3

• do not change the AV Delay (AVD) since ventricular sensing is occurring
• do not change the Lower Rate (LR) since the atrial sensing is occuring

Question 4

During a sensing test, what is done for a patient that is AP-VS?

Answer 4

• do not change the AV Delay since ventricular sensing is occurring
• decrease the lower rate to allow intrinsic atrial conduction to occur

Question 5

How does changing the Lower Rate (LR) help determine the atrial sensing threshold?

Answer 5

decreasing the LR extends the A-A interval and reduces Atrial Pacing to allowing for intrinsic conduction

Question 6

During a sensing test, what is done for a patient that is AP-VP?

Answer 6

• increase AV Delay to allow intrinsic ventricular conduction to occur
• decrease the lower rate to allow intrinsic atrial conduction to occur

Question 7

During a threshold test, what is done for a patient that is AS-VS?

Answer 7

• increase rate to 10-15 more than current rate or to 90 ppm to overdrive the atrium, then decrement the voltage until loss of capture
• decrease the AV Delay to pace the ventricles, then decrement the voltage until loss of capture

Question 8

During a threshold test, what is done for a patient that is AP-VS?

Answer 8

• do not change the rate, decrement the voltage until loss of capture
• decrease the AV Delay to pace the ventricles, then decrement the voltage until loss of capture

Question 9

During a threshold test, what is done for a patient that is AS-VP?

Answer 9

• increase rate to 10-15 more than current rate or to 90 ppm to overdrive the atrium, then decrement the voltage until loss of capture
• do not change the AVD, decrement the voltage until loss of capture

Question 10

During a threshold test, what is done for a patient that is AP-VP?

Answer 10

• do not change the rate, decrement the voltage until loss of capture
• do not change the AVD, decrement the voltage until loss of capture
