RHYTHMx AED ECG Analysis Algorithm Version 112-2025-109 B 2-2
Post-resuscitation, if the victim is breathing, the AED should be left attached
to allow for acquisition and detection of the ECG rhythm. If a shockable
ventricular tachyarrhythmia recurs, the device will charge automatically and
advise the operator to deliver therapy (G3) or automatically deliver the shock
(G3 Automatic).
When a patient is a child or infant up to 8 years of age, or up to 55 lbs
(25kg), the device should be used with the Model 9730 Pediatric Attenuated
Defibrillation Electrodes. The therapy should not be delayed to determine
the patient's exact age or weight.
RHYTHMx AED ECG Analysis Algorithm
The RHYTHMx™ AED ECG analysis algorithm provides ECG detection
capabilities. The features available with the AED include the following:
◆ Detection Rate
◆ Asystole Threshold
◆ Noise Detection
◆ Non-Committed Shock
◆ Synchronized Shock
◆ Pacemaker Pulse Rejection
◆ SVT Discriminators
◆ Supraventricular Tachycardia (SVT) Rate
Detection Rate
All ventricular fibrillation (VF) and ventricular tachycardia (VT) rhythms at
or above this rate will be classified as shockable. All rhythms below this rate
will be classified as non-shockable. This rate is programmable between 120
bpm (beats per minute) and 240 bpm via MDLink Software by the Medical
Director. The default Detection Rate is 160 bpm.
Asystole Threshold
The asystole baseline-to-peak threshold is set at 0.08 mV. ECG rhythms at or
below 0.08 mV will be classified as asystole and will not be shockable.
