Q

ICD

Define detection window

A

Uses a moving window of 10 intervals to make decisions

Detection is satisfied when 8/10 intervals are fast

Rate is the criterion

Q

ICD

Define duration

A

Durations ensures that the arrhythmia is sustained before initiating treatment

6/10 must remain fast

Rate and duration are criterion
