ECG analysis system
category specifications
function Evaluates impedance of adhesive pads for proper contact with the patient’s skin,
and evaluates the ECG rhythm and signal quality to determine if a shock is
appropriate.
shockable rhythms Ventricular fibrillation (VF) and some ventricular tachycardias associated with a
lack of circulation, including ventricular flutter and polymorphic ventricular
tachycardia (VT). The HeartStart uses multiple parameters to determine if a
rhythm is shockable.
NOTE: For patient safety reasons, some very low-amplitude or low-frequency rhythms
may not be interpreted as shockable VF rhythms. Also, some VT rhythms usually
associated with circulation will not be interpreted as shockable rhythms.
non-shockable rhythms SMART Analysis is designed to detect non-shockable rhythms as defined by
AHA/AAMI DF-80. See following table. On detection of any non-shockable
rhythm, the HeartStart prompts user to perform CPR if needed.
pacemaker detection Pacemaker artifact is removed from the signal for rhythm analysis.
artifact detection If electrical “noise” (artifact) is detected which interferes with accurate rhythm
analysis, analysis will be delayed until the ECG signal is clean.
analysis protocol Depending on results of analysis, either prepares for shock delivery or provides
a pause. For details of protocol, see Appendix F, “Configuration.”
