5.
6.
Place three electrodes on Subject as shown
in Fig. 5.6.
Setup continues…
Attach the electrode lead set SS2L to the
electrodes following Fig. 5.6.
 Place one electrode on the medial surface of each leg, just above the
ankle. Place the third electrode on the right anterior forearm at the wrist
(same side of arm as the palm of hand).
Note For optimal electrode adhesion, place electrodes on skin at least 5 minutes
before Calibration is started.
Fig. 5.6 Lead II Setup
When the electrode leads are connected properly, the LEAD II electrode
configuration will be established. The electrode lead cables are each a different
color and the pinch connectors on the ends of the cables need to be attached to a
specific electrode. Follow Fig. 5.6 to ensure that each cable is connected to the
proper electrode.
The pinch connectors work like a small clothespin, but will only latch onto the
nipple of the electrode from one side of the connector.
7.
Have Subject lie down and relax.
Position the electrode cables such that they are not pulling on the electrodes.
Connect the electrode cable clip (where the cable meets the three individual
colored wires) to a convenient location (can be on Subject’s clothes). This
will relieve cable strain.
Subject should not be in contact with nearby metal objects (faucets, pipes,
etc.), and should remove any wrist or ankle bracelets.
8.
9.
Start the BIOPAC Student Lab program.
Choose lesson L05 and click OK.

10. Type in your filename and click OK.
11. Optional: Set Preferences.
 Choose File > Preferences.
 Select an option.
 Select the desired setting and click OK.
Lesson L05 is Electrocardiography (ECG) I.
Type in a unique identifier. Click OK to end the default setup.
This lesson has optional Preferences for data and display while recording. Per
your Lab Instructor’s guidelines, you may set:
Journal Text: show minimum guiding text vs. detailed text
Grids: show or hide gridlines
ECG filter: set bandwidth
Heart Rate Data: Calculate and display Heart Rate data – enabled by default
We recommend that you leave Heart Rate data enabled. Heart Rate data
is derived by finding each R-R interval in the ECG channel and then
calculating the corresponding rate (in BPM).
Rate (BPM) = (60 sec./minute) / (R-R Interval -sec.)
END OF SETUP
B.
CALIBRATION
Since Heart Rate data requires a full, preceding R-R interval, it is
always delayed from ECG data by one R-R Interval and the data is only
updated once per R-R interval.
Time scale: set horizontal time scale from 10-120 seconds
Lesson Segments: Specific recording segments may be omitted based on
instructor’s preferences.
Calibration establishes the hardware’s internal parameters (such as gain, offset, and scaling) and is critical for optimum
performance. Pay close attention to the following calibration steps.
FAST TRACK
DETAILED EXPLANATION
1.
Double check electrode connections and
make sure Subject is supine, relaxed, and
still.
Make sure the electrodes adhere securely to the skin. If they are being pulled up,
you will not get a good ECG signal.
Subject must be relaxed and as still as possible during the Calibration. The
electrocardiograph is very sensitive to small changes in voltage caused by
contraction of skeletal muscles, and Subject’s arms and legs need to be relaxed
so that the muscle (EMG) signal does not corrupt the ECG signal.
2.
Click Calibrate.
The Calibrate button is in the upper left corner of the program window. This
will start the calibration recording, which will stop automatically after eight
seconds.
Subject needs to remain supine, relaxed, and still throughout calibration.
3.
Check the calibration data:
At the end of the 8-sec
calibration recording, there
should be a recognizable ECG
waveform with no large
baseline drifts. If data
resembles Fig. 5.7 (with
allowance for any difference in
vertical scaling), proceed to the
Data Recording section.
 If similar, proceed to Data Recording.
 If different, Redo Calibration.

END OF CALIBRATION
C.
If data shows any large baseline drifts, check that electrodes are making good
contact, then click Redo Calibration and repeat the entire calibration sequence.
RECORDING LESSON DATA
FAST TRACK
1.
Prepare for the recording and have Subject
lie down and relax.
*IMPORTANT
This procedure assumes that all lesson
segments are enabled in lesson
Preferences, which may not be the
case for your lab. Always match the
segment title to the segment reference
in the journal and disregard any
references to excluded segments .
DETAILED EXPLANATION
Four conditions* will be recorded: Supine, Seated, Breathing deeply, and After
exercise. Subject will perform tasks in the intervals between recordings.
In order to work efficiently, read this entire section so you will know what to do
for each recording segment. Subject should remain in a supine position and
continue to relax while you review the lesson.
Hints for obtaining optimal data:

a) The electrocardiograph is very sensitive to small changes in voltage caused
by contraction of skeletal muscles. To minimize artifact:

Subject’s arms and legs need to be relaxed so that the muscle
(EMG) signal does not corrupt the ECG signal.

Recording continues…
Subject should be as still as possible and should not talk or laugh
during any of the recording segments.
 Subject should be in a relaxed state for each recording segment
and in the position noted for each segment.
b) When asked to sit, Subject should sit with arms relaxed at side of body and
hands apart in lap, with legs flexed at knee and feet supported.
c) For Steps 5-6: Click Resume as soon as possible after Subject sits up in
order to capture the heart rate variation, but not while Subject is in the
process of sitting up or there will be excessive motion artifact.
Supine
2.
Click Record.
When Record is clicked, the recording will begin and an append marker labeled
“Supine” will automatically be inserted.
3.
Record for 20 seconds and then click
Suspend.
Subject is supine for seconds 0-20. The recording should halt, giving you time
to review the data and prepare for the next recording segment.
4.
Review the data on the screen.
If data looks similar
to Fig. 5.8, proceed
to Step 5.

If correct, go to Step 6.
Fig. 5.8 Supine

5.
If different, click Redo
Seated
Have Subject quickly get up and sit in a
chair, with arms relaxed and feet
supported. (Fig. 5.9)
Recording continues…
The data might be different if:
a) The Suspend button was pressed prematurely.
b) An electrode peeled up, causing a large baseline drift, spike, or loss of
signal.
c) Subject has too much muscle (EMG) artifact.
In this case, click Redo and repeat Steps 2-4. Note that when Redo is clicked,
the data that was just recorded will be erased.
Subject should sit with arms relaxed at side of body and hands apart in lap, with
legs flexed at knee and feet supported for seconds 21-40.
Fig. 5.9 Proper position for ‘Seated’ segment
In order to capture the heart rate variation, it is important that you resume
recording as quickly as possible after Subject sits. However, it is also important
that you do not click Resume while Subject is in the process of sitting or you
will capture motion artifact.
6.
Click Resume as soon as possible once
Subject sits and relaxes.
When you click Resume, the recording will continue and an append marker
labeled “Seated” will be automatically inserted.
7.
Record for 20 seconds and then click
Suspend.
Subject remains seated, relaxed, and still while maintaining the original
breathing rate.
The recording should halt, giving you time to review the data and prepare for the
next recording segment.
8.
Review the data on the screen.
 If similar, go to Step 9.
If data looks similar
to Fig. 5.10,
proceed to Step 9.
Fig. 5.10 Seated
 If different, click Redo.
The data would be different for the reasons in Step 4. If different, redo the
recording by clicking Redo and repeating Steps 5-8. Note that once you press
Redo, the data that was just recorded will be erased.
Deep Breathing
9.
Click Resume.
10. Subject remains seated and inhales and
exhales as completely as possible for five
prolonged (slow) breath cycles.
Recorder inserts event markers at a
corresponding inhale and exhale.
 “start of inhale” — press F4
 “start of exhale” — press F5
When Resume is clicked, the recording will continue and an append marker
labeled “Deep breathing” will be automatically inserted.
Subject remains seated, relaxed, and still.
After the recording begins, Subject should complete a series of five prolonged
(slow), deep, breath cycles, inhaling fully and exhaling completely.
Note It is important to breathe with long, slow, deep breaths
to help minimize the EMG artifact.
During this time, Recorder presses F4 at start of one inhale and F5 at start of
corresponding exhale to insert pre-labeled markers. These event markers will help
you locate data to complete Table A in the Data Report.
 Labels can also be entered manually: press F9 on Windows or Esc on Mac;
labels can be added or edited after data is recorded.
11. Click Suspend after 5 breath cycles.
The recording should halt, giving you time to prepare for the next recording
segment.
12. Review the data on the screen.
If data looks similar
to Fig. 5.11, proceed
to Step 13.

If similar, go to Step 13.
Recording continues…
Fig. 5.11 Deep Breathing

If different, click Redo.
The data might be different for the reasons in Step 4.
Note The “Deep breathing” recording may have some baseline drift (as shown
previously in Fig. 5.11). Baseline drift is fairly normal and unless it is
excessive, it does not necessitate redoing the recording.
If incorrect, click Redo and repeat Steps 9-12. Note that when Redo is clicked,
the data that was just recorded will be erased.
After exercise
13. Have Subject perform an exercise to
elevate his/her heart rate.
Subject should perform an exercise to elevate his/her heart rate fairly rapidly,
such as running up stairs, push-ups, or jumping-jacks.
Note You may remove the electrode cable pinch connectors so that Subject
can move about freely, but do not remove the electrodes.
If you do remove the cable pinch connectors, you must reattach them
following the precise color placement in Fig. 5.6 prior to clicking
Resume.
In order to capture the heart rate variation, it is important that you resume
recording as quickly as possible after Subject has performed the exercise.
However, it is also important that you do not click Resume while Subject is
exercising or you will capture motion artifact.
14. Click Resume.
When Resume is clicked, the recording will continue and an append marker
labeled “After exercise” will be automatically inserted.
15. Record for 60 seconds.
16. Click Suspend.
17. Review the data on the screen.
Subject is seated in a relaxed state, recovering from exercise.
The recording should halt.
If data looks similar to Fig. 5.12, proceed to Step 18.

If similar, go to Step 18.
Fig. 5.12 After Exercise

If different; click Redo.
Recording continues…
ACTIVE LEARNING PORTION
The data would be incorrect for the reasons in Step 4.
Note The “After exercise” recording may have some baseline drift (as shown in
Fig. 5.12 above). Baseline drift is fairly normal and, unless excessive,
does not necessitate redoing the recording.
If incorrect, clicking Redo and repeating Steps 13-17. Note that once you press
Redo, the data that was just recorded will be erased.
With this lesson you may record additional data segments. Design an experiment
to test or verify a scientific principle(s) related to topics covered in this lesson.
You are limited to this lesson’s channel assignments; however the electrodes may
be moved to different locations on the subject.
Design Your Experiment
Use a separate sheet to detail your experiment design, and be sure to address
these main points:
A. Hypothesis
Describe the scientific principle to be tested or verified.
B. Materials
List the materials will you use to complete your investigation.
C. Method
Describe the experimental procedure—be sure to number each step to make it
easy to follow during recording. Run Your Experiment
D. Set Up
Set up the equipment and prepare the subject for your experiment.
E. Record
Use the Resume, and Suspend buttons to record as many segments as
necessary for your experiment.
Click Done when you have completed all of the segments required for your
experiment.
Analyze Your Experiment
F. Set measurements relevant to your experiment and record the results in a
Data Report.
18. Click Done.
19. Click Yes.
A dialog with options will be generated. Make your choice and continue as
directed. If choosing the “Record from another Subject” option:
a) Attach electrodes per Setup Steps 5-7 and continue the entire lesson
from Setup Step 9.
b) Each person will need to use a unique file name.
20. Remove the electrodes. (UNLESS
THERE IS ANOTHER
EXPERIMENT TO PERFORM)
Remove the electrode cable pinch connectors. Peel off the electrodes and discard
the electrodes; BIOPAC electrodes are not reusable. Wash the electrode gel
residue from the skin, using soap and water. The electrodes may leave a slight
ring on the skin for a few hours. This is normal, and does not indicate that
anything is wrong.
END OF RECORDING
IV.
DATA ANALYSIS
In this section, you will examine ECG components of cardiac cycles and measure amplitudes (mV) and durations (msecs) of the
ECG components.
Note: Interpreting ECGs is a skill that requires practice to distinguish between normal variation and those arising from medical
conditions. Do not be alarmed if your ECG is different than the normal values and references in the Introduction.

The measurement boxes are above the marker region in the data window. Each
measurement has three sections: channel number, measurement type, and result.
The first two sections are pull-down menus that are activated when you click
them.
 Brief definition of measurements:
Value: Used to measure BPM, the value measurement displays the amplitude
value for the active channel at the point selected by the I-beam cursor.
Data Analysis continues…
2.
 CH 40 heart rate data is only updated at the end of an R-R interval so it
remains constant within an R-R interval; therefore, the Value (BPM)
measurement will be accurate from any selected point in the R-R interval.
 Value can also be determined by using the Arrow tool while holding down
the left mouse button.
Delta T: Used to measure duration, this is the difference in time between the
beginning and end points of the selected area.
P-P (peak-to-peak): Used to measure amplitudes, this finds the maximum value
in the selected area and subtracts the minimum value in the selected area.
BPM: Use only if CH 40 was not recorded. The Beats Per Minute
measurement first calculates the difference in time between the beginning and
end of the selected area (seconds/beat), and divides this value into 60
seconds/minute.
The “selected area” is the area selected by the I-beam tool (including endpoints).
Set up your display window for optimal
viewing of three complete cardiac cycles
from the initial “Supine” segment.

The Heart Rate plot
needs two cycles to
“catch up” to the
ECG plot because
heart rate is
calculated with ECG
data.
Fig. 5.15 Overlap sample: Heart Rate and ECG after supine Subject is seated
Adjust Baseline allows you to position the waveform up or down in small
increments so that the baseline (isoelectric line) can be exactly zero. After Adjust
Baseline is pressed, Up and Down buttons are generated. Simply click these to
move the waveform up or down. This is not needed to get accurate amplitude
measurements, but may be desired before making a printout, or when using grids.
