SYNCHRONIZED SHOCK
The AED is designed to synchronize shock delivery on the R-wave. The AED will automatically attempt to synchronize
to the R-wave. If delivery cannot be synchronized within one second, a non-synchronized shock will be delivered.
PACEMAKER PULSE DETECTION
The AED contains pacemaker pulse detection circuitry to detect pulses from an implanted pacemaker.
SVT DISCRIMINATORS
The Responder AED is supplied with the SVT Discriminator enabled and with the default setting "NO THERAPY
FOR SVT". With the factory default setting of "NO THERAPY FOR SVT", the Responder AED will not shock an
SVT rhythm.
SVT Discriminators are sophisticated filters that analyze the morphology of the ECG waveforms and distinguish
VF/VT from SVT and Normal Sinus Rhythms (NSR). The SVT Discriminator will only be applied to rhythms that fall
between the Detection Rate and the SVT Rate. The factory default setting for this feature is "NO THERAPY FOR SVT",
however the Medical Director can enable this feature using MDLink on the Responder AED.
SVT RATE
All rhythms with rates between the Detection Rate and SVT Rate will be screened through a number of SVT
Discriminators to classify them into VF/VT or SVT. Rhythms classified as SVT between the two set rates are
not shockable. All SVT rhythms above the rates will be classified as shockable. The SVT Rate must be greater
than the Detection Rate and is selectable between 160 and 300 bpm or, “NO THERAPY FOR SVT” can be
selected via MDLink Software by the Medical Director on the Responder AED only.
CONTINUOUS MONITORING
Responder AEDs are supplied with the Continuous Monitoring disabled. This is the factory default setting.
The Responder AED can monitor the ECG rhythms continuously throughout the rescue including during
Charge and CPR mode. Continuous Monitoring will interrupt CPR if a shockable rhythm is detected. When
CPR is interrupted, the prompt, “DO NOT TOUCH PATIENT. ANALYZING RHYTHM” will be issued. Only one
false interruption will be allowed during a single rescue cycle. CPR mode will not be interrupted if preceded by
three consecutive shocks. The factory default setting for Continuous Monitoring in CPR is disabled, however
the Medical Director can enable/disable this feature via MDLink software.
