Cardiac Airbag Technical Manual 1
1. General
1.1 System Description
The Cardiac Airbag family of Implantable Cardioverter
Defibrillators (ICDs) detects and treats ventricular
tachyarrhythmias as well as provides rate adaptive bradycardia
pacing support. The ICDs are designed to collect diagnostic data
to aid the physician’s assessment of a patient’s condition and the
performance of the implanted device. The Cardiac Airbag ICDs
are specifically designed to have reduced complexity for implant
and follow-up, yet provide essential therapies for conversion of
life threatening ventricular tachyarrhythmias.
There are 10 programmable parameters to simplify the implant
procedure, and detailed diagnostic information is stored for up to
10 ventricular tachycardia (VT) episodes and 3 treated
ventricular fibrillation (VF) episodes. There are 30 minutes of
single-channel IEGM storage available to record spontaneous
and induced ventricular tachyarrhythmias. The Cardiac Airbag is
restricted to storage of diagnostic information up to and including
3 treated ventricular fibrillation episodes.
The Cardiac Airbag ICDs provide therapy for ventricular
tachyarrhythmias with programmable defibrillation therapy. The
ICDs provide high energy biphasic shocks with the first shock
having with programmable energies of 20 or 30 joules and up to
8 shocks per VF episode. The remaining 7 shocks in the
therapy progression are pre-set at 30 joules.
The Cardiac Airbag family of ICDs includes the following
members:
• Cardiac Airbag provides therapies for ventricular
tachyarrhythmias and single chamber rate adaptive
bradycardia pacing support.
• Cardiac Airbag-T is identical to the Cardiac Airbag with
the added functionality of BIOTRONIK’s Home
Monitoring system. The Home Monitoring System
enables automatic exchange of information about a
patient’s cardiac status from the implant to the physician
remotely.
