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 include the following:
• Detection Rate
• Asystole Threshold
• Noise Detection
• Non-Committed Shock
• Synchronized Shock
• Pacemaker Pulse Rejection
• SVT Discriminators
• Supraventricular Tachycardia (SVT) Rate
• Continuous Monitoring
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. The Responder AED detection rate is 160 bpm.
ASYSTOLE THRESHOLD
The asystole peak-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 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 will
issue the prompt " ANALYSIS INTERRUPTED. STOP PATIENT MOTION " to warn the operator. The AED will
then proceed to reanalyze the rhythm and continue with the rescue.
NON-COMMITTED SHOCK
After the AED 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 will advise that the rhythm has
changed and issue the prompt " RHYTHM CHANGED. SHOCK CANCELLED. " The AED will override the charge
and continue ECG analysis.
