Bio 202 - Unit #3 Case Studies: 1- Blood, Heart, and Vessels 1)WHy are lymph nodes enlarged (adenopathy)? How does this fit with his CBC test? J.T’s lymph nodes are enlarged due to a high count of white blood cell count . Jt has a high white blood cell count because his body is trying to fight off an infection. 2)…
(no electrical charge) • P-R interval – represent the period from atrial to ventricular depolarization. The time requires transmitting an action potential through the entire conduction system. • Q-T – interval – period from ventricular depolarization to ventricular repolarization. The time require for action potential to occur within the ventricles This patient will not have a normal EKG. First, their cardiac output is below normal.…
2.1. Test Procedure Before data was analyzed, the Easy Pulse circuit had to be tuned to the team members’ specific pulse in order to produce transparent and accurate data. This is due to the fact that each individual person has relatively unique heart rates and pulse strengths. While the A0 pin on the circuit board was connected to the AI0+ channel on the Elvis board, P1 or the Gain was turned completely clockwise using a screwdriver. From there, P1 was rotated clockwise until the peak of each pulse were relatively close to 5V. Once tuned, data on the pulse signal was acquired and analyzed using the program Pulse Monitor.vi.…
1. What does the PR interval on the ECG represent? What is the normal value? The P-R interval is the interval between the beginning of electrical excitation of the atria and the beginning of excitation of the ventricles and its normal value is 0.12- 0.20 seconds.…
- The purpose of the Electrocardiogram test is to monitor and measure the quantity and quality of the electrical rhythm of the heart. Understanding the electrical rhythms of the heart is important because your heart's electrical system controls the timing of your heartbeat and you would have to understand how the electrical rhythm of the heart should be to know what problems may be occurring. There are three common variables that are encountered in an electrocardiogram which are the direction in which the signal is moving, the speed at which the signal is moving and the mass of the tissue through which the signal is moving. There are three different parts of an electrical signal which are P wave, QRS complex and T wave. P wave passes slowly…
To further expound upon the theme of the story, Alexie uses the incongruity of characters. Both of the main characters, William and Fekadu, defy the expected stereotypes that society would give them. William, a Native American, said that “He didn’t want to choose between Ernie Hemingway and the Spokane Tribal Indians, between Mia Hamm and Crazy Horse, between The Heart is a Lonely Hunter and Chief Dan George” (Alexie 55). William is not the only character who denies the preconceived image of his heritage, Fekadu also does this. Initially, Fekadu seems to fit the stereotype of a African American taxi driver; however, there is much more to his story.…
The initials 'EKG' in EKG technician stand for electro cardiogram. It follows that the EKG technician is tasked with performing electrocardiograms on patients in order to monitor the condition of a person's cardiovascular system. That said, the specific role of an EKG tech will vary from one industry and institution to another. For instance, EKG technicians working in an emergency room may be called upon to perform additional duties that are slightly different from those of an EKG technician working in a private cardiologist's clinic. Typically though, the core duties of a technician include preparation of the EKG room, setting up the EKG equipment, taking the electrocardiograms and then cleaning up the EKG room after each session.…
1. All subjects will have two meetings regarding the informed consent form. The first will be a group session before the medical testing and will discuss the study purpose, goals, design, and what their participation entails. Furthermore, study design will be explained thoroughly such as what placebo-controlled means and what a sentinel block is. The second meeting will be a one-on-one session with subjects after completing their medical tests.…
The title of the isorhythmic motet is “Felix virgo/ Inviolata genitrix/ Ad te suspiramus” and is composed by Guillaume de Machaut. The structure of this motet is an isorhythmic motet in that it is made up of two poems where the motet gets its lyrics. The translation of the motet title is “Happy Virgin/ Inviolate mother/ To you” in reference to the Virgin Mother Mary. The last words of the title “...…
The Cardiovascular System: An Overview of Blood, Vessels, and Heart – Healthy to Diseased The cardiovascular system, also known as the circulatory system, consists of the heart, blood, and blood vessels (Mertz, 2004). The cardiovascular system moves oxygenated blood and nutrients through to and removes carbon dioxide and wastes out of the body’s cells. (Miracle of the Human Body, 2010) I will provide an overview how a healthy cardiovascular system does this by first discussing the anatomy of it, in a healthy state, and then the physiology of it, also in a healthy state, this will include how the pulmonary and systemic circuits work.…
If a person's sanity is in question, don't you think you should look through all the facts and interpret them carefully and accurately? Edgar Allen Poe wrote, "The Tell-Tale Heart", a short story told in the first person by the self-confessed murderer of an old man. The narrator is clearly sane. However, many other readers of the story believe that the narrator of “The Tell-Heart” is insane. The Narrator knew what he was doing was wrong.…
He is not a reliable narrator because he is emotionally unstable. Poe heightens the tension and fear running through the mind of the narrator. There is a clear connection between the language used by the narrator and his psychological state. The narrator switches between calm, logical statements and quick, irrational outbursts. Poe effectively conveys panic in the narrator’s voice, and the reader senses uneasiness and growing tension in the story.…
In 1997, the American Heart Association brought together the organization’s stroke-related activities as American Heart Association/American Stroke Association. In an effort to get women involved in increasing stroke awareness, The Power of Women in Media was created as a brand that symbolizes women banding together through the effective use of social and traditional media to increase stroke awareness and whose mission it is to empower women to begin a movement that will stimulate collective responsibility and action among women to end the over 7.2 million deaths of women worldwide from stroke for lack of awareness of the risk factors. SITUATION ANALYSIS Client Organization Background, Mission, and Values The American Heart…
The poem “Head, Heart” by Lydia Davis is short, but has a very powerful message. To me, the author is speaking of a broken heart story. An issue that a lot of people my age struggle with. The main thing that pointed this out to me was the name of the poem, “Head, Heart.” These two things are what people turn to when they struggle with decisions about a relationship.…
Cardiac Dysrhythmia Cardiac Dysrhythmia also known as cardiac arrhythmia is a group of of conditions where the heartbeat is irregular and or too fast or too slow. Tachycardia is known as a heart rate that is over 100 beats per minute for adults ,while Bradycardia is too slow with below 60 beats per minute. Majority of arrhythmia issues are not serious, but some predispose one to complications like heart failure or a stroke. Arrhythmia are the leading cause of sudden cardiac death, with 400,000 victims a year. There are four main types of arrhythmia, premature beats, supraventicular arrhythmias, atrial fibrillation, and bradycardia.…
