Conducting a Stress Test with a Master’s Step Device
Use the following instructions to conduct a stress test with a Master’s
Step device, if it is selected in the Stress Setup.
1. Prepare the patient as described in Chapter 3.
2. From the Main Menu , press F3 to select the Stress ECG option.
The Enter Patient Data window opens.
3. Enter patient data as described in Chapter 4.
Be sure you enter accurate information for Date of Birth , Gender ,
and Weight . The number of steps is determined by these three
parameters.
4. Adjust the stress options as necessary:
This includes the speed and gain, finite residual filter, pacemaker
enhancement, printer leads, test protocol, report format, and target
heart rate. For more information on setting these options, refer to
“Stress Options” on page 7-6
5. Record a preliminary ECG.
This may be seated, standing, supine, or hyperventilating, depending
on the requirements of the selected protocol.
6. Begin the pretest phase to allow the patient to warm up.
a. Remove the leadwires from the patient, but leave on the
electrodes.
This prevents the patient from tripping on the leadwires during
the test.
b. Instruct the patient to take a step whenever the MAC 1600
system beeps.
c. Press the Pretest key.
7. Press the Exercise key to begin the test.
The duration of the exercise phase is dependent on the selected
protocol:
SINGLE is 90 seconds, DOUBLE is 180 seconds, and
TRIPLE is 270 seconds.
When the test is complete, the first POST EXER. stage begins and
the ELECTR.ON message appears.
8. Reattach the leadwires to the electrodes.
The median report prints at pre-configured intervals during the post
exercise stages. When the last post exercise stage is complete, a
summary report with trends and tables print.
