8.4 Cardiac rhythm analysis
The Saver One automatically analyses the patient's heart rhythm. This phase is highlighted by the following
commands:
Icon do not touch
the patient on with
fixed light

Icon type of pads
used (adult / child)
During cardiac rhythm analysis, the patient's body must not be touched and must not be subjected to vibrations or
movements. The Saver One analysis software was designed to recommend defibrillation shock treatment only if the
patient is suffering from the following arrhythmias:
VF Ventricular Fibrillation
Peak to peak Amplitude min. 200 µVolts
Some rhythms with very low amplitude or low frequency VF may not be
interpreted as shockable.
VT Ventricular tachycardia
(including ventricular flutter and
polymorphic ventricular tachycardia)
Rhythm frequency min. 180 bpm and peak-to-peak amplitude min.200 µVolts
Some rhythms with very low amplitude or low frequency VT may not be
interpreted as shockable.
The Saver One detects both noise artefacts in the ECG, caused, for example, by patient movement,
defibrillation electrode adjustment, and electronic disturbances from external sources. In these cases the
analysis is delayed or interrupted.
The Saver One is able to detect and filter impulses coming from an implanted pacemaker.
