RHYTHMX

AED ECG ANALYSIS ALGORITHM

The RHYTHMx AED ECG analysis algorithm provides superior ECG detection capabilities, allowing it to be placed on

patients at risk for sudden cardiac arrest. The features available with the AED Pro 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 configurable between 120 bpm (beats per

minute) and 240 bpm. Service can change this rate using the ServiceLink software. The default Detection Rate is 160

bpm. The Responder AED Pro 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.

NOISE DETECTION

The AED Pro will detect noise artifact in the ECG. Noise could be introduced by excessive moving of the patient or

electronic noise from external sources like cellular and radiotelephones. When noise is detected, the AED Pro will issue

the prompt “ANALYSIS INTERRUPTED. STOP PATIENT MOTION” to warn the operator. The AED Pro will then proceed

to reanalyze the rhythm and continue with the rescue.

NON-COMMITTED SHOCK

After the AED Pro advises a shock, it continues to monitor the patient ECG rhythm. If the patient’s rhythm changes to a

non-shockable rhythm before the actual shock is delivered, the AED Pro will advise that the rhythm has changed and

issue the prompt “RHYTHM CHANGED. SHOCK CANCELLED.” The AED Pro will enter the CPR mode and prompt,

"START CPR".

SYNCHRONIZED SHOCK

The AED Pro is designed to synchronize shock delivery on the R-wave. The AED Pro will automatically attempt to

synchronize to the R-wave. If delivery cannot be synchronized within one second, a non-synchronized shock will be

delivered.

PACEMAKER PULSE DETECTION

The AED Pro contains pacemaker pulse detection circuitry to detect pulses from an implanted pacemaker.
