Pacemaker

Question 1

The first three letters refer to?

Answer 1

1. chamber paced
2. chamber sensed
3. response to sensed events

Question 2

What does AOO, VOO, or DOO mode mean?

Answer 2

AOO ( pacing the atrium alone )
VOO (pacing the ventricle only)
DOO (pacing in the atrium and ventricle without sensing or response)

Question 3

These modes (ending in OO) are known as?

Answer 3

Asynchronous modes

Allow pacing to be maintained and prevent interference of electrocautery caused by the absence of sensing

Question 4

What is the result of VVI pacing?

Answer 4

This mode results in ventricular pacing, with sensing in the ventricle alone, and the response is inhibition.

Question 5

What is the result of DDI pacing?

Answer 5

DDI means pacing in the atrium and ventricle, sensing in the atrium and ventricle, and the response is constrained to inhibition.

Question 6

What does DDD pacing mean?

Answer 6

DDD pacing means pacing in atria and ventricle, sensing in atria and ventricle, and a dual response (both triggered and inhibited). This is the most common pacing mode.
