The purpose of these lab exercises is to understand the function and importance Of an electrocardiogram. This lab will demonstrate how stress levels or different elevations can affect human heart rate. Furthermore, the equipment used in the experiment Will show the functions in the right and left arm; as well as, in the right and left ankles.
Finally, the lab will serve a purpose as a way to know how to read an electrocardiogram and calculate the heart rate.
Introduction An electrocardiogram can be used to record activity during the cardiac process of pumping and returning blood to the body and heart because of the electric rent that spreads through the tissue of the heart and to the surface of the body. By using four electrodes, one on your left and right wrist and one on the upper left and right foot.
From that information a person is able to record the electrical potentials produced by the heart. Beginning tooth lab involved a reading trot the electrocardiogram and then calculating the heart rate by comparing the waves to what the electrocardiogram reading said.
The electrocardiogram is divided into five main parts. The first small peak is the p wave; it represents trial deportation (Eric, 2011). Next is the SIRS ample: the SIRS consist of the Q, R and S.
The complex will occur because of the electrical events produced as the ventricles deplorable (Eric, 2011). Lastly, there is the T wave; it represents the ventricular revitalization (Eric, 2011). The voltages recorded on an electrocardiogram can be compared to on table 28. 1 in the Ninth Edition Sellers laboratory manual.
In the lab experiment there will be a comparison of the BPML, PR interval, SIRS complex and the CT interval All in which you have an average that you can see if you are in the “normal” range Of. If someone has a BPML above a hundred; it is called Tachycardia (Eric, 2011)_ If anemone has a BPML below sixty; it is called Brickyard (Eric, 2011). Following BPML, you have the PR interval the normal for that range is 0. 16-0. 18 seconds (Eric, 2011). Continuing with the next one is SIRS complex the normal for the complex is 0. 08 seconds (Eric, 2011). In contrast, the CT interval normal is between 0. 3-0. 4 seconds (Eric, 2011).
Each one of the test can express something different in relation to your heart rate. Purpose of the lab was to teach someone how to read an electrocardiogram but as well to know how to calculate heart rate. If there was vibration of the table or he position in which someone was standing/laying then it can affect the reading of the electrocardiogram. Methods The protocol for this lab experiment involved a few things, First Off gather the machine that will be used to test the heart rate. Connect the MPH unit to an electrical outlet with the power supply (Eric, 201 1), Do not turn the MPH quiet yet though.
Plug in the SSL lead cables, into the CURERS cable (Eric, 2011). From that point all jewelry should be taken off and the electrodes should be placed above your inner wrist on both left and right arm also one electrode above our ankle on the left and right foot. After putting the electrodes on, plug in the information that is asked: age and sex. Now connect the right arm lead to the right arm, the left arm lead to the left arm, the right ankle lead to the right ankle and the left ankle lead to the left leg. At that point have a partner make sure blood pressure is not to high, then press Okay.
The reading Will take ten seconds. Stand straight up and look straight ahead. Try not to move while the test is being run. The electrocardiogram Will then print a reading. From there calculate and compare the findings to table 28. , page 376 in the laboratory manual. In the lab experiment there was four things to find from the electrocardiogram. Before starting to calculate the test decide which lead you will be using: or II, The first test being Beats per minute. The way to find the beats per minute was to calculate the resting heart rate by counting how many millimeters occur between Vivo peaks (such as R to R) (Eric, 2011).
After calculating the resting heart rate, then times that by 0. 04 seconds/mm. This will give a calculation of second/ beats. From that take sixty seconds/ minutes and divided by seconds/ beats. This ill give the calculations of battlement’s, The next interval to be found was PR interval the way to calculate that is to begin at the P wave and end at the beginning of the SIRS wave, Count how many boxes were in between those two and multiply by 0. 04 again. After that calculation there was the SIRS complex here start at the first deflection of the Q wave and ends when the S wave returns to the baseline.
Again count the boxes because they represent millimeters and times by 004 Last you will calculate the CT interval. This interval is determined with the beginning of the Q wave to the end of the T wave (Eric, 2011). Same as the above, count the boxes that your intervals lye in and times by 0. 04_ After all calculations are done compare the numbers given on page 376 table 28. 1. This diagram shows where to find P, Q, R, S, T. It helps when trying to identify and calculating the different test The picture was found on Google pictures.

Sec Shorten with increased heart rate I Within norm- no lower than normal. I In the chart above it has five ms each mm concerning different test.
The first row talks about Beats per minute; in that row it ask what my beats per minute was, gives if it is over a hundred then its Tachycardia and if it is below sixty it is brickyard and then ask if it was normal or not, My beats per minute were a hundred and fifty so it is considered Tachycardia. The next row shows PR interval, mine avgas . 2 but the normal is 0. 16-0. 18 sec so no my PR interval is not in the norm. Pillowing that is the SIRS complex it consisted of mine being _08 which was normal for a SIRS complex. The last test was the CT interval; again my numbers feel short. Mine avgas which is lower than the norm.
The table above can also be found in Sellers Anatomy and Physiology laboratory manual on page 376. Discussion NOW that the experiment has been tested, the results are in there comes the analysis part of the process. After had determined my calculation saw where my beats per minute were over a hundred; this consider me to be Tachycardia. Tachycardia refers to an abnormally fast resting heart rate. When examining what Tachycardia was and how it can be affected made me see that different scenarios will affect the beats per minute. Anxiety, caffeine, stress can all cause someone to have such a rapid heartbeat. Member from when taking the chromatogram that I was stressed about school, had a red hull that morning which lead me to believe that it had an effect on the way my results were. The next test was PR interval. Again I was not in the norm, mine was , 12 meaning it was lower than the normal. This could mean have a partial VA heart block. With hat said am not too worried about it because of what was stated earlier. I stressed, had more caffeine than on a normal day. SIRS complex was next. I was in the norm for that test with C,08 seconds, The last test was the CT interval where again was lower than the normal, coming out with a 0. Second rate. As I did research on the CT interval I saw where studies have shown CT interval can be passed along through the genes 0. This would make since in my cause because my father had serious heart issues. I passed one out of the four test which could mean that have blockage in different places but it can also mean here was minor interferences With the test For example; the science building at Reinhardt University is under construction so the table could have vibrated during the test or because I was standing up I moved.
All the little things can and will have a effect on the test. TO make the test more efficient, think you should take the test lying down. Also have more leads placed around the body. It could make the test more accurate From my observation of my hypothesis; father was different confliction from outside sources then it can affect the reading of the electrocardiogram; show he hypothesis to be true.
