The Ischemic Index
336
The table below lists Ischemic Index values and their corresponding patient conditions.
The patient’s response to myocardial ischemia may be altered using the Ischemic Index Sensitivity
parameter found in the Cardiovascular view (Additional Parameters). To make the patient less
sensitive to ischemia, lower the value below the default setting. To make the patient more sensitive,
increase the value above the default setting.
Model-Driven ECG Rhythm Ischemic Index (I.I.)
Normal Sinus Rhythm (NSR) I.I. ≥ 0.90
Mild ST Segment Depression 0.90 > I.I. ≥ 0.70
Moderate ST Segment Depression 0.70 > I.I. ≥ 0.60
Premature Ventricular Contractions (PVCs) 0.60 > I.I. ≥ 0.40
Ventricular Tachycardia (VTach) 0.40 > I.I.
Ventricular Fibrillation (VFib) 1 minute after VTach
Asystole 1 minute after VFib
