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.…
Introduction The purpose of this lab was to determine the rate, function, and integrity of the heart during an exercise EKG. An electrocardiogram measures the electrical activity of the heart over time. In this lab a subject will exercise for about 15 minutes, not including rest times and the EKG will measure the heart’s activity.…
This paper explains how to asses a new patient coming in for chest pain and how an Electrocardiogram (EKG) and other tests would be performed to diagnose the patient’s condition. Using two scholarly resources the paper will further explain the information that will be needed to know before performing the EKG on this new patient. A physician can request an EKG for different reasons in this scenario the patient has had a history with Myocardial Infarctions (MI’s) and when he comes in to the ER complaining of angina and shortness of breath the EKG technician notices another MI is present. Different procedures and blood tests can be done to open the coronary artery that is causing the MI and to determine the damage to the area that the MI has…
Whether or not they had a collaboration agreement or protocols in place, when a patient comes into a clinic complaining of chest pain, an EKG and serial enzymes should have been performed. Although most patients who present with chest pain do not have a life threatening condition, health care providers must use common procedures and protocols to ensure that urgent management is obtained for those that do. Provider’s clinical judgment still remains an overriding factor, but basic clinical tools of history, physical examination, and EKG are key in the risk stratification of these patients. An initial EKG is the simplest most cost effective strategy, and should be considered a vital sign in a patient with chest pain (Kontos, Diercks, &Kirk, 2010). The AHA states that an initial EKG should be performed within 10 minutes of arrival to an ED, and also recommends that if the initial EKG is negative then serial EKGs be performed at 5-10 minute intervals as long as symptoms persist.…
For the heart doctors listen for what the heart sounds like, how loud the sound is, and how often each sound occurs (Nall, 2015). Information you can receive from listening to your heart is troubled sounds such as a skipped…
A mandatory electrocardiogram could easily bring out unknown heart problems (Heart Screening for High School Athletes, 2010, p. 1).…
Everyone knows regular, daily exercise is beneficial to the heart. It helps reduce the risk of heart disease, maintains a healthy body weight, lowers blood pressure, and improves cholesterol. A difference of appearance can be identified between the hearts of people who exercise routinely and those of highly trained athletes. Athletic hearts undergo cardiac remodeling of chambers and physiological changes as a result of extreme conditions placed on the heart over a long period of time. The heart adapts to these conditions by increasing in chamber size and wall thickness to eject more blood to the rest of the body.…
A EKG shows the heart's electrical activity as line tracings on paper. What External defibrillators it is a portable device that checks the heart…
Statement of the Problem Health care facilities are consistently looking for new ways to improve patient satisfaction in all aspects of the hospital experience (Gebremedhn, Chekol, Amberbir, & Flatie, 2015). Patient satisfaction is important for both improving patient recovery and for improving hospital ratings and overall atmosphere of the facility (Gebremedhn et al., 2015). Because of this, hospital staffs are considering different ways to ameliorate the experience of patients, especially in the aspect of pain relief in anesthesiology. Anesthesiology is the practice of medicine dedicated to pain relief. Health care professionals are currently studying further the role of anesthesiology in improving patient satisfaction.…
The study conducted by Cleeland, Gonin, Hatfield, et al., included 1,308 patients with previously diagnosed recurrent or metastatic cancer who had undergone surgery more than 30 days from the onset of the study. The patients came from a total of 54 facilities: 12 university cancer centers (267 patients); 12 community-based hospitals and practices (382 patients); and 30 community clinical oncology programs (659 patients). Group 1 – Patients Patients completed the Brief Pain Inventory at the time of a regular appointment. Patients were asked to rate several types of pain on a scale of 0 to 10. (0 being the “no pain” and 10 being “pain as bad as you can imagine.”)…
The quiz was based on the homework we went over in class on Tuesday. On the quiz we had to identify the rate and rhythm of the heartbeat by using our EKG paper, see if the EKG have any P waves in order to find out the PR interval. After we figure out if there is a QRS interval we have to determine the rhythm interpretation. The quiz was not that hard, but there were two of the questions that were really tricky, because they looked very similar.…
Cindy, Wow! What a whirlwind year for 2016….with perpetually moving forward projects, commitments and workload! First, you were doing double duty at the beginning of the year, covering for me while I was off with knee replacement recovery. You did this with grace and your everlasting happiest place on earth approach, despite adding the complexities of the programs to your daily work life.…
The pacemaker helps treat an issue called arrhythmias. Arrhythmias are problems with the beat of your heartrate. There are 4 different types of arrhythmias, premature which is when you get extra beats (the most common type), Supraventricular tachycardia is when your heart beats too fast, ventricular rhythm issues can halt the ventricle from pumping blood into your body (this could result in cardiac arrest), and Bradycardia is when your heart beats too slow meaning not enough blood gets to your brains sometimes meaning you could pass out. If someone is unlucky to have arrhythmias the heart could possible not be able to pump enough blood throughout your body. This can result in symptoms like fatigue, shortness of breath, or fainting.…
The heart is an essential part of a human’s body. It is a muscular organ located at the center of the circulatory system that pumps blood throughout the body. The system comprises of veins, arteries, and capillaries, and these blood vessels carry blood to and from all areas of one’s body to sustain life. It beats around 100,000 times and pumps around 2,000 gallons per day. The heart is vital to one’s health and everything that goes on in his or her body.…
CHAPTER 2 2.1 ELECTROCARDIOGRAM The ECG Signal is a graphical representation of the electromechanical activity of system. The various propagation action potentials within the heart produce a current flow, which generates an electrical field that can be detected, in significantly attenuated form, at the body surface, via a differential voltage measurement system. The resulting measurement, when taken with electrodes in standardized locations, is known as the electrocardiogram. The ECG signal is typically in the range of ±2 mv and requires a recording bandwidth of 0.05 to 150 Hz.…
