ECG Analysis Performance
CATEGORY NOMINAL SPECIFICATIONS
Function Evaluates impedance of defibrillation pads for proper contact with patient skin,
and evaluates the ECG rhythm and signal quality to determine if a shock is
appropriate.
Protocols Follows pre-programmed settings to match local EMS guidelines or medical
protocols. The settings can be modified using the setup options.
Shockable Rhythms Ventricular fibrillation (VF) and certain ventricular tachycardias, including
ventricular flutter and polymorphic VT. The H
EARTSTREAM FR2 uses multiple
parameters to determine if a rhythm is shockable.
NOTE: For safety reasons, some very low-amplitude or low-frequency rhythms may not be
interpreted as shockable VF rhythms. Also, some VT rhythms may not be interpreted as shockable
rhythms.
Asystole
On detection of asystole, provides CPR prompt at programmed interval.
Pacemaker Detection On detection of a pacemaker (in advanced mode only), provides screen display of
PACEMAKER DETECTED alert, and M3860A includes pacemaker artifact in
ECG display. In both models, pacemaker artifact is removed from the signal for
rhythm analysis.
