October 9th, 2016, after being discharged just three days prior, a 44-year-old African American female presented in the emergency department with complaints of shortness of breath with minimal activity and chest pain that radiates to the back and shoulders. Vitals signs were taken and reveled a heart rate of 134, blood pressure of 219/147 and a respiratory rate 28. Observation of the patient showed that she was slightly diaphoretic and anxious. Lab work was ordered to be drawn as well as an ECG and the admission process began. Admitting diagnosis recorded was tachycardia, elevated troponin, acute exacerbation of congestive heart failure, acute chronic congestive heart failure, chest pain and pleuritic chest pain.
The patient has a past medical
Cynthia Adae was taken to Clinton Memorial Hospital on June 28, 2006. She was taken to the hospital with back and chest pain. A doctor concluded that she was at high risk for acute coronary syndrome. She was transferred to the Clinton Memorial hospital emergency room. She reported to have pain for two or three weeks and that the pain started in her back or her chest. The pain sometimes increased with heavy breathing and sometimes radiated down her left arm. Cynthia said she had a high fever of 103 to 104 degrees. When she was in the emergency room her temperature was 99.3, she had a heart rate of 140, but her blood
There are several different heart problems that show up as an abnormal EKG reading. For example, a heart block can occur when there is a delay in the signals coming from the SA node, AV node, or the Purkinje fibers. However, clinically the term heart block is used to refer to an AV block. This delays or completely stops communication between the atria and the ventricles. AV block is shown on the EKG as a delayed or prolonged PR interval. The P wave represents the activity in the atria, and the QRS complex represents ventricular activity. This is why the PR interval shows the signal delay from the AV node. There are three degrees of severity, and if the delay is greater than .2 seconds it is classified as first degree. Second degree is classified by several regularly spaced P waves before each QRS complex. Third degree can be shown by P waves that have no spacing relationship to the QRS complex. Another type of blockage is bundle branch block. This is caused by a blockage in the bundle of His, creating a delay in the electrical signals traveling down the bundle branches to reach the ventricles. This results in a slowed heart beat, or brachycardia. On an EKG reading this is shown as a prolonged QRS complex. A normal QRS is about .8-.12 seconds, and anything longer is considered bundle branch block. Another type of abnormal EKG reading is atrial fibrillation, when the atria contracts very quickly. On the EKG this is shown by no clear P waves, only many small fibrillating waves, and no PR interval to measure. This results in a rapid and irregular heartbeat. On the other hand, ventricular fibrillation is much more serious and can cause sudden death if not treated by electrical defibrillation.
The primary concern for Mr. Miller would be preventing further ischemia and necrosis of the myocardial tissues, preventing serious complications such as cardiac dysrhythmias and heart failure, as well as relieving his chest pain that radiates to his left arm. Preventing further ischemia and necrosis of the myocardial tissue will help prevent the development of heart failure due to myocardial infarction, whereas relieving his pain will help reduce his episodes of shortness of breath, and will also help to reduce any anxiety and restlessness he may be having from being in pain and short of breath.
In this lab, I took two recordings of my heart using an electrocardiogram. An electrocardiogram, EKG pg. 628 Y and pg. 688 D, is a recording of the heart's electrical impulses, action potentials, going through the heart. The different phases of the EKG are referred to as waves; the P wave, QRS Complex, and the T wave. These waves each signify the different things that are occurring in the heart. For example, the P wave occurs when the sinoatrial (SA) node, aka the pacemaker, fires an action potential. This causes the atria, which is currently full of blood, to depolarize and to contract, aka atrial systole. The signal travels from the SA node to the atrioventricular (AV) node during the P-Q segment of the EKG. The AV node purposefully delays
Stethoscope functionality generally has not changed over the past few decades evolving from the monaural hollowed out wooden tube first invented in the early 1800’s by Rene Laennec to the more familiar long multi tubular version, improved upon by George Cammann 50 years later, we so typically see today. The core components of a modern stethoscope are comprised of ear tips, binaural piece, tubing and a diaphragm with a bell on the back. The bell transmits low frequency waves all the way up to the ear pieces, while the diaphragm is designed to carry the higher frequency sound. The two fathers of the stethoscope left little room for improvement on the near perfect design for just over a century until a Harvard Medical School professor by the name of David Littmann turned the simple listening device into the versatile diagnostic tool resting around almost every health care professional’s neck today.
My clinical rotation for NURN 236 is unique in that all patients I care for at Union Memorial Hospital in Baltimore, Maryland have a diagnosis of heart failure (HF). HF occurs when the heart is unable to pump adequate blood supply, resulting in insufficient oxygen and nutrients to the tissues of the body (Smeltzer, Bare, Hinkle, and Cheever, 2012). Approximately 670,000 Americans are diagnosed with HF each year and is the most common hospital discharge diagnosis among the elderly (Simpson, 2014). Moreover, according to the Centers for Medicare and Medicaid Services (CMS), HF is the leading cause of 30-day hospital readmission followed by acute myocardial infarction (AMI) and pneumonia (medicare.gov|Hospital Compare, 2013).
Client Profile: Lane Bronson is a 55 year old male with a history of angina, hypertension, Type 2 diabetes, COPD, and sleep apnea. He comes to the physican’s office complaining of worsening shortness of breath. His skin tone is grey, and his angina is worsening. Previously stable, he now does not get relief from rest or nitroglycerin. The physician called 911 and had Mr. Bronson directly admitted to the hospital.
In “The Tell-Tale Heart” by Edgar Allan Poe, there are only five characters mentioned in the story: the narrator, the old man, and three police officers, none of whom is ever named. Throughout the story, the narrator tells the audience over and over that he is not mad. He becomes obsessed with trying to prove that he is not a madman and eventually goes crazy in the end. He tells the story of how he kills the old man after seven nights of watching him sleep. He has nothing against the old man and actually likes him, but it is the old man’s pale blue eye with a film over it that overwhelms the narrator with anger. This is when he decides to rid of this “vulture eye,” by murdering the old man. After finally finishing what he had set out to do, three policemen show up because of a complaint about a shriek. The narrator assures them that it was him that had shrieked because of a nightmare and asks the officers to sit with him. While talking with them, confident that they knew nothing, he starts to hear a noise increasingly get louder. He eventually cannot take it anymore and
On admission, a complete physical assessment was performed along with a blood and metabolic panel. The assessment revealed many positive and negative findings. J.P. was positive for dyspnea and a productive cough. She also was positive for dysuria and hematuria, but negative for flank pain. After close examination of her integumentary and musculoskeletal system, the examiner discovered a shiny firm shin on the right lower extremity with +2 edema complemented by severe pain. A set of baseline vitals were also performed revealing a blood pressure of 124/80, pulse of 87 beats per minute, oxygen saturation of 99%, temperature of 97.3 degrees Fahrenheit, and respiration of 12 breaths per minute. The blood and metabolic panel exposed several abnormal labs. A red blood cell count of 3.99, white blood cell count of 22.5, hemoglobin of 10.9, hematocrit of 33.7%, sodium level of 13, potassium level of 3.1, carbon dioxide level of 10, creatinine level of 3.24, glucose level of 200, and a BUN level of 33 were the abnormal labs.

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.
Arrhythmia I am doing my report on Arrhythmia. It affects the cardiac muscle, the heart. Arrhythmia causes three types of problems. It causes the heart to pump too slowly (bradycardia), it causes the heart to pump too fast (tachycardis), and it causes the heart to skip beats (palipations).
AIM: - the aim of this experiment is to find out what the effects of exercise are on the heart rate. And to record these results in various formats. VARIABLES: - * Type of exercise * Duration of exercise * Intensity of exercise * Stage of respiration
Heart failure, also known as CHF or congestive heart failure affects nearly 5 million people in the U.S. yearly with 1.4 million of those being under the age of 60. Half of these will die within five years of being diagnosed. (Heart Failure Statistics) CHF usually occurs over a period of time as the heart’s pumping ability grows weaker and can either consist of right-side heart failure, left-side heart failure, or both. “Right-side heart failure occurs if the heart can't pump enough blood to the lungs to pick up oxygen” and causes symptoms such as edema. “Left-side heart failure occurs if the heart can't pump enough oxygen-rich blood to the rest of the body” and will show symptoms of dyspnea and fatigue. (What is heart failure?)
Is this a mind game? It’s all in your head they say, the power of overthinking will ruin you and lead you to paranoia and insanity. It’s a sad yet devastating reality that many people face with mental illnesses, which takes a toll over their lives and is a cause for their uncontrollable actions. In the article ““the tell tale heart” by Edgar Allan Poe, the narrator is very paranoid and feels that he is being watched yet tries to prove that he is not insane although his actions are strange and out of character and he killed the old man. The narrator is psychotic and tries to prove he’s not by fighting the disease to be free from his mental illness.
