Conducting an Exercise Stress Test
For each new exercise stress test, the user must select the appropriate profile and protocol. Changes in any protocol
can be made in the settings.
1. Select Patient Information and then select the Stress button.
2. Change the Target Heart Rate if necessary.
3. Select the type of exercise equipment to be used and modify settings if necessary.
4. Select Begin to start pre-exercise.
The ECG waveforms are displayed as they are acquired from the patient.
•
Examine the 12-lead rhythm display for artifact (noise) or baseline drift. Re-prep and replace
electrodes as necessary to obtain satisfactory tracings.
•
If a lead fail condition exists in any of the displayed leads, square waves appear for leads in fault and
the lead labels are displayed in the center of the screen.
5. Select Begin. The patient demographics window will appear.
Pre-Exercise Phase
During the Pre-exercise phase, the user should:
1. Enter the patient's baseline BP.
•
Enter three characters in the systolic field, select Done, and the display automatically advances the
cursor to the diastolic field.
2. Obtain baseline ECGs (i.e., supine, standing, and hyperventilation 12-lead ECGs) as desired.
3. Instruct patient on the proper technique for using the exercise equipment.
4. If desired, change the ECG display by touching the ECG waveform and selecting the desired display
options.
Acquiring a Resting ECG
1.
Have the patient resting on a bed or exam table. If the exam table is narrow, tuck the patient's hands
under his/her buttocks to ensure their muscles are relaxed. Touch the ECG button to print.
2. Ask the patient to stand up and move to the treadmill or ergometer. You may need to reposition the
electrodes depending upon the 12-lead ECG acquired.
