workload than an athlete. Although not completely accurate, this can be a very good indicator of fitness. MATERIALS AND METHODSECGIn order to carry out the electrocardiogram experiment a number of materials needed to be obtained. Three disposable electrodes along with the electrode gel were needed. The BIOPAC program, Mac Computer, and the SS 2L lead (black, red, white) were used to collect data on the subject. The electrodes were connected to the body (skin). The black lead was placed on the anterior right leg just above the ankle joint. The same was done with the red lead expect placement was on the left leg. The white lead was placed on the right wrist just above the palm. After correct placement of these electrodes, the SS 2L lead was connected to the CH 2 port. Lesson 3 was opened and the setup icon was clicked. After the setup as completed, record was clicked and the ECG recorded for 30 seconds. This was done while the subject was sitting relaxed. Using the I-beam tool, peak-to-peak measurements were taken. This value was the inter-beat interval. With that number, beat per minute was found (BPM = 60 / IBI).Cardiac Physiology 5The second phase of the experiment was to connect the pulse transducer to the index finger or the right hand. The SS 2L lead was disconnected from CH 2 and placed in the CH 1 port. The SS 4L lead was then connected to the CH 2 port. Lesson 6 was opened on BIOPAC and setup was clicked. Again, after that was completed, record was clicked and it recorded for 30 seconds. The area between the peak of the R wave and the peak in the pulse group was highlighted using the I-beam tool. This number was used to calculate feet per second that the pulse waveform took to travel form your heart to arm. This value was then used to calculate miles per hour. Heart Sounds and Blood PressureA stethoscope, sphygmomanometer, alcohol swabs, and a subject were first obtained. The earpieces on the ste...
