3. Describe the electrical conduction system of the heart. The normal electrical conduction in the heart allows the impetus that is engendered by the sinoatrial node (SA node) of the heart to be propagated to, and stimulate, the cardiac muscle (myocardium). The myocardium contracts after stimulation. It is the set up, rhythmic stimulation of the myocardium during the cardiac cycle that allows efficient contraction of the pump, thereby permitting blood to be pumped throughout the torso. 4. State
On Tuesday, November 24, 2015, I, Joseph Spagnolia Safety and Security Agent for IKEA Schaumburg Store #210, was working in the office with Safety and Security Manager, David Chavez when he received call at approximately 08:35 from Safety and Security Agent Dan Burns who was working in reception when he called stating that there is a possible CODE 1000, Chavez advised Burns to go ahead and start the CODE 1000 procedures. Burns stating that the CODE 1000 in the South Mechanical Room. Chavez and I
There are many disadvantages of this traditional Electrocardiography electrodes are metal allergy can causes skin irritation, short term use, too much expensive and single use electrodes to overcome these disadvantages non-contact Electrocardiography sensor are used here named as EPIC (Electric potential Integrated Circuit) sensor. EPIC sensor is discovered in UK which has specialty of sensing without
1) Which of the following is used to distinguish the diagnosis of MI (Myocardial Infarction) from that of Unstable angina? a) Serum levels of Cardiac Biomarkers (Troponin, CK-MB) b) Electrocardiograph (ECG) test c) The presence of S4 Heart sound d) Pain lasts for less than 5 minutes in an MI Rationale The correct answer is A because serum levels of cardiac biomarkers such as troponin and CK-MB are used for the final diagnosis of Myocardial infarction (STEMI, NSTEMI). Electrocardiograph (ECG) testing
Classes are from 8 AM to 5 PM on Monday, Tuesday, Thursday, and Friday. Then on Wednesday you must refresh on skills that you learn as an EMT, take paramedic preparatory classes, pharmacology, and electrocardiography (ECG) interpretation. During clinical rotations all paramedic students must be able to start IVs give injections, practice intubation, and assist with birth and delivering babies. It's necessary to have all students to work internships at the
My appreciation for science does not have a starting point, probably because it was right there all along. I just remember asking for a microscope for Christmas and questioning every change my body was going through while growing up. (Chemistry is often referred to as the ‘’central science’’). My curiosity and urge to know everything often encourage me to ask myself questions. In the process of looking for answers chemistry proved to have an explanation for everything. In order to challenge myself
Problem: Left-sided holodiastolic, murmur with point of maximal intensity over the left base. The murmur is decrescendo shaped. Differential diagnoses: The most likely diagnosis for the cardiac murmur in this horse is aortic insufficiency, as a result of degenerative changes to the aortic valve. In aortic insufficiency, the murmur heard is due to regurgitation through the defective aortic valve. Aortic insufficiency presents clinically with a holodiastolic decrescendo murmur, with maximal intensity
However, our prediction that caffeine consumption is a factor responsible increasing respiration rate and pulse rate was not observed but rather, results imply that caffeine does not have a visible effect on short-term exercise performance. Therefore, the alternate hypotheses are rejected in favour of the null. is This may be because caffeine only has a positive effect in prolonged, intense exercise that last up to 2 hours (Hogervorst 2008). As respiratory rate and pulse rate are just simple measures
Stroke is the third cause of death in the United States. Stroke is the interruption of blood in the brain. According to the American heart association 730000 Americans are affected by stroke per year 160000 resulting in death. Also stoke is s the number one cause of disability of the United States. The main reason why strokes occurs is hypertension, smoking, heart disease and family history. However 90% of the strokes is because of fat accumulated in the carotid artery or when the blood clots becoming
Firefighters respond to a variety of a calls every day, these include (but are not limited to): fire-related, medical, MVCs and HazMat. Response statistics from Toronto Fire Service’s 2011 annual report show that while fire-related calls have been relatively stagnant throughout the last 7 years, medical calls have been significantly increasing (table 1; figure 1). Heart disease and stroke account for roughly 350,000 hospitalizations per year in Canada and first responses to related illnesses and
Monitoring The appropriate selection of the specific physiologic parameters that should be monitored during the MRI procedure is vital for patient safety. They consist of MRI safe Pulse oximeter, Electrocardiograph and respiratory bellows or pneumatic capsules. This physiologic parameter is measured using pulse oximetry, a monitoring technique that measures the oxygenation of tissue. Due to which oxygen saturated blood absorbs differing quantities of light compared with unsaturated blood, the amount
My career goals is to start my career as a Medical Assistant working in a medical office. I would like to learn every aspect of the job before specializing in one area. My second career goal is to work in a hospital setting where I can get experience working with patients in that type of setting. After I have gained some experience in the medical arena I plan to continue working with cardiac patients. Medical assistants perform routine clerical and clinical duties in order to maintain efficiency
Treatment for coronary heart disease can range from simple changing your lifestyle to having medical or surgical procedure done. Although there is no cure for this disease, doctors and scientist have gone to great lengths to further understand and treat this disease. From testing on animals to controversial procedures, to finding alternative types of treatment whether it be medical or holistic. Has any research been successful? And what is to come for this disease in the future? According to the
Throughout my undergraduate Sport and Exercise Science degree at The University of Birmingham, I became fascinated by the interaction between how we physiologically react to stress and health/behavioural outcomes. It was my dissertation and health psychology module which first aroused this interest, and completing a critical essay, debating whether high or low cardiovascular reactivity to acute psychological stress is the most detrimental to health, further enhanced this passion. Receiving 92% for
1.0 INTRODUCTION OF BIOMETRICS A thousands years ago until now, human use their physical and behaviour characteristic to recognize such as face, voice, . However, in the middle of 19th century, chief of the criminal identification division of the police department in Paris, Alphonse Bertillon, had idea to use body measurements to identify crime. In late 19th century, it was identified with the discovery of far more important and practical distinctiveness of human fingerprint. Soon after this discovery

There is a strong focus on data driven school decision making and the goal is to prepare students to be successful in the twenty-first century. The school has a capacity for 2500 students
Ecstasy (MDMA) is a highly illegal psychoactive drug that is known by many different, harmless sounding, street names including Adam, Clarity, Disco Biscuit, E, Eve, Go, Lover’s Speed, Mandy, Molly and X. What Ecstasy is actually comprised of however, is the very dangerous 3,4-methylenedioxymethamphetamine or MDMA. The psychoactive drug itself was originally created in the 1900s as a compound to synthesize other drugs. In the 1970s some psychiatrists began experimenting with Ecstasy during physchotherepy
CHAPTER 2 INDUSTRIAL AUTOMATION 2.1 INTRODUCTION OF INDUSTRIAL AUTOMATION Automation is encompassing virtually every walk of Life. Automation solutions are required right from agriculture to space technology. Plant Automation is the necessity for the manufacturing industry to survive in today’s globally competitive market. 2.1.1 INVENTION OF AUTOMATION In 1935, Delmar S. Harder from GM invented the term ‘Automation’. After World War II, in 1946, he was working for Ford and found the requirement
Muscular Dystrophy (MD) is a disease that weakens the musculoskeletal system and affects the ability to move. MD also affects groups of muscles. In the 1860’s it was described that boys were progressively growing weaker, losing the ability to move and died at an early age. A decade after the first description a French, neurologist named Guillaume Duchenne gave account for thirteen boys with the most common and severe forms of Muscular Dystrophy. MD is being caused by a mutation of a gene within the
Technology continues to progress. Today, every business, school and organization thrive mostly because of a well-developed website or an application that is easily downloaded into any mobile device. Healthcare, as well has been progressively adding ways to incorporate the use of electronic devices. The use of the patient’s portal and the electronic health record are only a few technological advances in healthcare today. A bedside nurse working in an acute care has the competence with numerous gadgets
