It is important to have the capability to store and interchange reference QRST complexes. The monitor will analyze and store the reference QRST complexes of all leads, which can be easily compared to the following complexes. Upon initiation the monitor learns the reference ST values. Tracking ischemic changes in the QRST complex This may help the clinician to notice if ischemia is spreading to new areas. The “All leads” option shows ST values for all available ECG leads. When a Solar®, Dash® or CARESCAPE modular monitor is used, the user can also choose all leads to be shown as an alternative to ST number field. The fourth ST value shows the largest absolute ST lead of all monitored leads. The ST parameter window of a CARESCAPE or GE’s Datex-Ohmeda monitor shows three user selectable ST leads.

(Please consult “12RL Reconstructed 12 lead ECG Quick Guide” or the monitor’s manual for details.) With a 5-lead trunk cable analysis and trending are done for seven leads, and with a 3-lead trunk cable analysis and trending are done for one lead. With a 6-lead trunk cable continuous ST segment analysis and trending are done for eight leads, or for 12-leads if the 12RL™ algorithm is in use. With a 10-lead trunk cable GE monitors analyze and trend the ST segment changes continuously for 12 leads. The QRS analysis classifies each beat by using several criteria and rejects distorted complexes from the ST calculation. When the CARESCAPE™ Patient Data Module or Tram® module is used with a CARESCAPE modular monitor, the ST point can be manually adjusted. These points can also be adjusted manually when the E-PSM or E-PRESTN module is used.

The algorithm sets the ISO and J points automatically.
The system learns the ECG and stores the reference QRST complex. The ISO point is a point on the isoelectric line and is considered the baseline voltage of ECG. The sophisticated algorithms in GE monitors search for the J and isoelectric (ISO) points.
For monitoring purposes it is important that the measurement point is accurate to obtain a reliable trend of ST changes. Typically ST changes are measured at 60 ms or 80 ms after J-point. The ST segment begins at the point where the QRS ends (J-point). NOTE: The significance of the ST segment changes needs to be determined by a physician. NOTE: ST segment changes may also be affected by such factors as some drugs or metabolic and conduction disturbances.
