An Overview of the ST80i Stress Test System
2-16 ST80i Stress Test System Instructions for Use
Compare the current averages with reference ECG (resting, supine, hyperventilation
averages) and worst case for all 12 leads. ST80i is able to select a new ECG complex or
10s strip as the new reference. This can be done on the screen and is available at any point
during the test.
Hide or show the magnified beat, trends, anatomical representations (ST Map) and
average complexes that appear over the real-time waveform display
View a two-dimensional, color-coded anatomical representation of ischemic area/
segments (ST Map); 2D real-time updates anatomical representation (ST Map) every 10
seconds
Create events during the test with associated notes
View trend graphs for Heart Rate, METS, BP, SpO
