Arrhythmia analysis algorithm
The SAM 500P uses the HeartSine
samaritan ECG arrhythmia analysis
®
algorithm. This algorithm will evaluate the
patient's ECG to ascertain if a therapeutic
shock is appropriate. If a shock is required,
the SAM 500P will charge and advise the
user to press the shock button. If no shock
is advised, the device will pause to allow
the user to deliver CPR.
The SAM 500P ECG arrhythmia analysis
algorithm performance has been
extensively evaluated by using several
databases of real-life ECG traces.
Included in this are the American Heart
Association's (AHA) database and the
Massachusetts Institute of Technology
MIT – NST database. The SAM 500P ECG
arrhythmia analysis algorithm's sensitivity
and specificity meet the requirements of
IEC60601-2-4.
