Brady Special Features

AV Delay (short)
- try and mimic natural shortening of PR interval as heart rate goes up
- maintain cardiac output at high rate
- optimize filling
AV Delay (long)
- Encourage intrinsic conduction
- avoid unnecessary RV pacing
- try to maintain V-V syncrone
Sensing Automatic
- measure & adjust A+V sensitivity to maintain accurate sensing
- so you don't over pace!
Output (capture)

maximize battery life while maintaining an adequate safety margin
Refractory (PVARP)

Increase the 2:1 BLOCK point to allow atrial tracking at higher rates
Refractory (PVARP +)

Prevent PMT by tracking retrograde R waves
Refractory (PVARP TERMINATION)

Terminate PMT
Rate Modifiers
- provided normal decrease in HR at rest
- optimize hemodynamics to encourage intrinsic rythmn
Neurocardiogenic Syncope
- prevent sudden drop in rate
- increase rate to prevent syncope
