Conducting a Stress Test
For each new session, the user must select the appropriate profile and protocol for the stress test. Changes in any
protocol can be made in the settings.
1. Highlight and select the desired User Profile and Exercise Protocol and then click on New Exam.
NOTE: Manual control of any exercise protocol during the test is always available; however, this may
cause the X-Scribe to exit the current protocol. Selecting pause will halt the advancement of the current
stage. The clinician can re-enter the protocol at the stage and time where the protocol was paused. The
pause will be entered into the report for documentation. Users can also select an alternate protocol
during any stage of the stress procedure that will allow entry into a new protocol. Entry into a new
protocol will automatically advance the test to the beginning
of the next stage selected (i.e., if the test is in
stage three of the Bruce protocol, and a pharmacological protocol is preferred, X-Scribe will advance to
the beginning of stage four for the pharmacological protocol.).
A. If the patient was pre-registered, Work List will display a list of up to 100 patients to select from. Double
click the selected patient and the demographics area will be populated.
a. Select the percentage of maximum HR you would like to obtain. This can be in increments of 5
starting at 75% up to 100%. The clinician may also enter a target HR outside of the target
percentage to meet the clinician’s testing regiment.
b. Enter appropriate indications, medications, staff, and physician information.
c. Select OK.
NOTE: If the patient you require does not appear on the work list select SKIP to enter the patient
information manually.
B. If the patient was not pre-registered, the patient demographics screen will appear.
a. Populate fields with requested information.
b. Select OK.
2. The main window appears displaying the waveforms as they are acquired from the patient. By default, X-
Scribe displays pre-exercise, real-time ECG waveforms in a 6x2 format.
Examine the 12-lead rhythm display for artifact (noise), or baseline drift. Re-prep and replace electrodes
as necessary to obtain satisfactory tracings. (See Patient Preparation.)
If a lead fail condition exists in any of the displayed leads, a square wave appears for that lead on the
display and the lead in fault displays in red letters in the upper right corner of the screen. The lead
failure message appears when the DC offset is out of the normal operating range of +300 mV to -300
mV. In instances of simultaneous, multiple lead fail conditions, X-Scribe gives display priority to the
limb leads, followed by leads V1 through V6.
NOTE: Ensure the SCF is on and attempt to maintain a motionless patient for at least 30 seconds. This
will ensure a clean and clear signal during the stress test. A message will appear at the top right-hand
side of the display informing the clinician that the SCF filter is in the process of learning. Once this
message disappears the SCF has completed its learning process.
3. Select Begin or press F1. The patient demographics window will appear.
