CMS clinical criteria for devices

Note that the ICD, BiV pacer, BiV pacer/ICD and LVAD fields are disabled if the patient criteria do not meet CMS criteria. The criteria for the devices are below;

BiV pacer
CHF Class >= 3
EF <= 35%
QRS duration >120 msec

ICD
CHF Class 2-3B
EF <= 35%

BiV Pacer/ICD
Same as BiV pacer

LVAD
CHF Class 4
EF <= 25%
Mean survival <= 2 years

If you want to see the effect in the model anyway, make the patient characteristics match the criteria, then click on the device you want, then set the patient criteria back to the original values. In this case, the device will still be selected, even though it is disabled.
