... Force (N), ECG (mV) and heart rate (bpm) of the pithed frog. Figure 2. Force (N) per unit time (s) of the pithed frog. Figure 3. ECG (mV) per unit time (s) of the pithed frog. Table 1. Time between QRS and the start of ventricular contraction(s). 1. Observe the heart and describe its behavior. Is this behavior consistent with what is shown in the data above? Yes. The heart of the frog rhythmically contracts and relaxes. This behavior is supported by the general fluctuations observed force values and the consistent patterns of the ECG occurring in regular intervals. 2. Explain the basis for the delay between the atrial and ventricular contractions. The said delay is mainly caused by the A-V node and its adjacent conductive fibers, causing an overall delay of 0.13 second (Guyton and Hall 2006). Conduction in the transitional, nodal, and A-V bundles is dampened by the decreasing number of gap junctions along the pathway of conduction, creating great resistance against the conduction of excitatory ions from one fiber to another. This ensures that the atria completely empty blood into the ventricles before ventricular contraction occurs. 3. Describe the relationship between the ECG QRS complex and the beginning of ventricular contraction. What is the physiological significance of this relationship? A typical electrocardiogram normally exhibits P, Q, R, S, and T waves, all of which represent electrical voltages produced by the heart. The QRS waves occur as a...

...Heart Failure Christy Harding Western Governors University C155- Pathopharmacological Foundations for Advance Nursing Practice Heart failure affects nearly 6 million Americans. It is the leading cause of hospitalization in people older than 65. Roughly 550,000 people are diagnosed with heart failure each year (Emory Healthcare, 2014). Heart failure is a pathologic state where the heart cannot pump enough blood to meet the demand of the body’s metabolic needs or when the ventricle’s ability to fill is impaired. It is not a disease, but rather a complex clinical syndrome. The symptoms of heart failure come from pulmonary vascular congestion and inadequate perfusion of the systemic circulation. Individuals experience orthopnea, fatigue, dyspnea, cough with frothy sputum, peripheral edema, and decreased urinary output. Heart failure is caused by many conditions that damage the heart’s muscle. Any form of heart disease can lead to heart failure. A1. Pathophysiology Heart failure arises as a consequence of an abnormality in cardiac structure, conduction, rhythm, or function (Figueroa & Peters, 2006). Heart failure always begins with an index event. This event could be silent, as with the expression of a genetic mutation, or obvious, such as a myocardial infarction (Francis & Tang, 2003). Heart failure can be categorized into systolic ventricular dysfunction also known as systolic heart failure or diastolic ventricular dysfunction also known as diastolic heart failure...

Tsang 2* 1 Division of Cardiovascular Diseases and Internal Medicine, Mayo Clinic, Rochester, MN, USA; and 2Division of Cardiology, University of British Columbia, 2775 Laurel Street, Vancouver, BC, Canada Online publish-ahead-of-print 12 May 2011 The interest in the left atrium (LA) has resurged over the recent years. In the early 1980s, multiple studies were conducted to determine the normal values of LA size. Over the past decade, LA size as an imaging biomarker has been consistently shown to be a powerful predictor of outcomes, including major public health problems such as atrial fibrillation, heart failure, stroke, and death. More recently, functional assessment of the LA has been shown to be, at least as, if not more robust, a marker of cardiovascular outcomes. Current available data suggest that the combined evaluation of LA size and LA function will augment prognostication. The aim of this review is to provide a critical appraisal of current echocardiographic techniques for the assessment of LA function and the implications of such assessment for prediction and disease prevention. ----------------------------------------------------------------------------------------------------------------------------------------------------------Keywords Left atrium † Left atrial function † Echocardiography Introduction The left atrium...

To hear about our latest releases subscribe to the Planet PDF Newsletter. Three Ghost Stories THE SIGNAL-MAN ‘Halloa! Below there!’ When he heard a voice thus calling to him, he was standing at the door of his box, with a flag in his hand, furled round its short pole. One would have thought, considering the nature of the ground, that he could not have doubted from what quarter the voice came; but instead of looking up to where I stood on the top of the steep cutting nearly over his head, he turned himself about, and looked down the Line. There was something remarkable in his manner of doing so, though I could not have said for my life what. But I know it was remarkable enough to attract my notice, even though his figure was foreshortened and shadowed, down in the deep trench, and mine was high above him, so steeped in the glow of an angry sunset, that I had shaded my eyes with my hand before I saw him at all. ‘Halloa! Below!’ From looking down the Line, he turned himself about again, and, raising his eyes, saw my figure high above him. ‘Is there any path by which I can come down and speak to you?’ 2 of 97 Three Ghost Stories He looked up at me without replying, and I looked down at him without pressing him too soon with a repetition of my idle question. Just then there came a vague vibration in the...

...was first published. As I mention in the original introduction, the opportunity to write the book came while I was in law school, the result of my election as the first African-American president of the Harvard Law Review. In the wake of some modest publicity, I received an advance from a publisher and went to work with the belief that the story of my family, and my efforts to understand that story, might speak in some way to the fissures of race that have characterized the American experience, as well as the fluid state of identitythe leaps through time, the collision of cultures-that mark our modern life. Like most first-time authors, I was filled with hope and despair upon the book’s publication-hope that the book might succeed beyond my youthful dreams, despair that I had failed to say anything worth saying. The reality fell somewhere in between. The reviews were mildly favorable. People actually showed up at the readings my publisher arranged. The sales were underwhelming. And, after a few months, I went on with the business of my life, certain that my career as an author would be short-lived, but glad to have survived the process with my dignity more or less intact. I had little time for reflection over the next ten years. I ran a voter registration project in the 1992 election cycle, began a civil rights practice, and started teaching constitutional law at the University of Chicago. My wife and I bought a house, were blessed with two gorgeous, healthy, and mischievous daughters...

...U.S. Department of Justice Federal Bureau of Investigation 2012 The Strategic Information and Operations Center at FBI Headquarters is the 24/7 command post that monitors FBI operations and law enforcement activities around the globe. An FBI agent examines a potentially contaminated letter during a white powder training exercise. 2012 The FBI Story I A Message from FBI Director Robert S. Mueller, III For the FBI and its partners, 2012 was a year that reminded us once again of the seriousness of the security threats facing our nation. During the year, extremists plotted to attack—unsuccessfully, thanks to the work of our Joint Terrorism Task Forces—the U.S. Capitol, the New York Federal Reserve Bank, and other landmarks on U.S. soil. Tragically, on the 11th anniversary of 9/11, a hateful attack in Benghazi took the lives of the U.S. Ambassador to Libya and three other Americans. In the cyber realm, a rising tide of hackers took electronic aim at global cyber infrastructure, causing untold damages. High-dollar white-collar crimes of all kinds also continued to siphon significant sums from the pocketbooks of consumers. And in Newtown, Connecticut, 20 young children and six adults lost their lives in one of the worst mass shootings in American history, ending a year of violence that saw similar tragedies around the country. Working with its colleagues around the globe, the FBI is committed to taking a leadership role in protecting the nation. As you can see from...
