7.5 Heartbeat analysis
If the defibrillation pads have been applied correctly on the patient and the connector has been inserted in the dedicated
compartment, SMARTY Saver Plus will automatically analyse the patient’s heartbeat.
During the heartbeat analysis, the patient’s body must not be touched and it must not be subject to vibrations or
movements.
This stage of the analysis is characterised by the following voice messages:
Keyboard Illuminated Icons
Icon
“do not touch the
patient”
lit without blinking
Heartbeat analysis in progress
Icon
“pad type used”
Adult or child
lit without blinking
The analysis software of SMARTY Saver Plus has been designed to recommend the treatment with defibrillation shock
only if the patient is suffering from the following arrhythmias:
VF Ventricular Fibrillation
Peak-to-peak amplitude of min. 200 µVolts
Certain rhythms with a very low amplitude or low-frequency VF
can be interpreted as non-defibrillable.
VT Ventricular Tachycardia
(including ventricular flutter and
polymorphic ventricular tachycardia)
Rhythm frequency min. 180 bpm
and peak-to-peak amplitude of min. 200 µVolts
Certain rhythms with a very low amplitude or low-frequency VT
can be interpreted as non-defibrillable.
The presence of noise artefacts (caused, for example, from the patient’s movement or from the regulation of
the defibrillation electrodes) or electronic disturbance emitted by external sources may delay or interrupt the
ECG analysis.
Note: The SMARTY Saver Plus analysis software can filter pulses originating from an implanted pacemaker.
