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 from 120 bpm (beats per minute) to 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.
Noise detection
The AED will detect noise artifacts 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.
