Boston Manuals Flashcards
Device alerts - Shock/ATP
Device alerts - HM disconnected
Device alerts - Lead integrity
ICD
Define detection window
Uses a moving window of 10 intervals to make decisions
Detection is satisfied when 8/10 intervals are fast
Rate is the criterion
ICD
Define duration
Durations ensures that the arrhythmia is sustained before initiating treatment
6/10 must remain fast
Rate and duration are criterion
What determines which therapy is delivered?
Last interval in the zone
*last interval must be fast and in the zone for therapies to occur
Identify BS detection enhancements
Onset
Stability
V rate > A rate
A fib rate threshold
Sustained Rate duration
Morphology (Rhythm ID)
*only enhancements programmed ON at GOSH are Rhythm ID in VT and VT mom zone.
How many stages does BS reconfirmation have?
2 stages:
- during charge: 6/10
- After charge: 2/3
Programming for history of VF/SCD
VF - 180/230bpm - ATP, then shocks
VT - 160bpm - monitor only
Programming for history of VT/VF
VF - 200bpm - ATP, then shocks
VT - 160bpm - ATP, the shocks
Programming prophylaxis for VT/VF
VF - 180bpm - ATP, the shocks
VT - 160bpm - Monitor only
Programming for VF only (Long QT etc.)
VF - 220bpm - shocks
What Detection enhancements are only found in single chamber BS devices?
Onset
Stability
Shock if unstable
Sustained rate discrimination (SRD)
What is the magnet rate for Boston devices at each stage of life?
- BOL = 100
- ERI = 90
- EOL = 85
For Emblem SICD and Embelm SICD MRI, what models are MRI compatible?
