Understanding Diverticulitis: A Complete Study Guide for the Diverticulitis Patient
Summary
Diverticular disease was uncommon before the 20th century but is now one of the commonest health disorders in the Western world. Diverticular diseases are a group of health conditions that affect your gastrointestinal (digestive) tract. The most complicated form of diverticular disease is diverticulitis. Its symptoms are usually very uncomfortable, and in some cases, may result in serious complications. If it is left untreated, it can cause prolonged health problems. The symptoms of diverticulitis vary, ranging from mild to severe. The symptoms may be acute (appearing suddenly), or chronic (developing gradually over time). The most common symptom of diverticulitis is abdominal pain. North Americans and Europeans experience the abdominal pain on the left lower side (sigmoid colon), while in Asia it is usually on the right (ascending colon). But what causes diverticulitis really? Well, the disease diverticulitis develops when pouches form on your digestive tract, mostly in the colon (the large intestine). These pouches are known as diverticula. They form when weak spots balloon outward in your intestinal wall. It is important to note that inflammation and, in some cases, infection of the diverticula can cause diverticulitis. This can occur when partially digested food or feces blocks the diverticula opening. There is no single known cause of diverticular disease. Research and clinical experience has shown that multiple environmental and genetic factors may contribute to its development. Treatment prescribed for this condition depends on the severity of your condition. This book is a comprehensive guide on diverticulitis. It gives a detailed explanation of all you need to know about this condition including: The anatomy & physiology of the gastrointestinal tract A detailed literature on diverticulitis Complications associated with the disease Diagnostic procedure Diet guide You’ll be glad you got this guide! To your good health!!!

Heart Failure Prevention & Treatment
Summary
Heart failure, often referred to as cardiac failure or congestive heart failure, occurs when the heart is unable to pump sufficiently to maintain blood flow to meet the body’s needs. A lot of health conditions contribute to heart failure. These include coronary artery disease, myocardial infarction, also known as heart attack, high blood pressure, valvular heart disease, alcoholism, cardiomyopathy, and atrial fibrillation. These heart conditions contribute to heart failure by altering either the anatomy or physiology of the heart. Heart failure is a common, costly, and potentially fatal condition. About 40 million people were affected globally in 2015. In developed countries, around two percent of adults have heart failure, and in those over the age of 65, this increases to six to 10 percent. In the year after diagnosis, the risk of death is about 35 percent, after which it decreases to below 10 percent. Five percent of emergency hospital admissions in the UK are associated with this disease. Heart Failure Prevention & Treatment, as the name implies, discusses this health condition in details. It begins with a detailed explanation of the anatomy and physiology of the cardiovascular system (comprising the heart and the blood vessels) before proceeding to the disease condition. This will enable the listener to have a firm grasp of heart failure. Heart Failure Prevention & Treatment is written in simple English, with detailed explanation of medical terms to allow for easy comprehension by listeners in the nonmedical field. We hope that our listeners will find this audiobook a very useful tool in the war against the menace of cardiac failure.

Understanding ECG
Summary
Electrocardiography is the technique by which the electrical activities of the heart are studied. The spread of excitation through myocardium (the heart muscle) produces a local electrical potential. This causes the flow of small currents through the body, which acts as a volume conductor. These small currents can be picked up from the surface of the body by using suitable electrodes and recorded in the form of the electrocardiogram. This technique was discovered by Dutch physiologist Einthoven Willem, who is considered the father of the ECG. An electrocardiograph is an instrument by which the electrical activities of the heart are recorded. An electrocardiogram is a record or the graphical registration of electrical activities of the heart, which occur prior to the onset of mechanical activities. It is the summed electrical activity of all the cardiac muscle fibers recorded from the surface of the body. The electrocardiogram is recorded in 12 leads. The electrodes are fixed on the limbs. Usually, right arm, left arm, and left leg is chosen. The heart is said to be in the center of an imaginary equilateral triangle drawn by connecting the roots of these three limbs. This triangle is called Einthoven’s triangle. The electrical potential generated from the heart appears simultaneously on the roots of these three limbs. The electrocardiogram has great application in cardiovascular physiology, and the heart health as a whole. This book, which can be listened to in less than 24 hours will furnish you with the skills you need to totally crush ECG and its interpretation. With it, you can successfully tackle NCLEX at first sitting!
