SVT (Superventricular Tachycardia) DISCRIMINATORS
The Responder AED Pro 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 Pro 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
Service can change the settings for this feature using the ServiceLink software.
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 by Service between 160 and 300 bpm or, “NO THERAPY FOR SVT” can be selected by
Service using the ServiceLink software.
RESCUE PROTOCOL
The AED Pro rescue protocol is consistent with the guidelines recommended by the American Heart
Association (AHA)
1
European Resuscitation Council (ERC) and the International Liaison Committee
on Resuscitation (ILCOR).
Upon detecting a shockable cardiac rhythm, the AED Pro advises the operator to press the SHOCK button to deliver a
shock and then advises the operator to start CPR.
Note:
The standard CPR protocol of 120 seconds can be modified from 60 to 180 seconds in MDLink.
