Write An Essay On Atrial Fibrillation

Most physicians and people who acquired the problem usually know it as A-FIB, a shorter term for atrial fibrillation. Atrial fibrillation deals with the cardiovascular system, in particular, the heart in the body. It is defined as, “the electrical signals that control this system are off-kilter. Instead of working together the atria do their own thing, causing fast fluttering heartbeat, also known as arrhythmia” (WEBMD). In a normal pumping blood of the heart the atria would squeeze first, followed by the ventricles of the heart. A-fib can be a serious issue if not treated, due to the inadequate pumping of the blood, causing a higher chance of heart failure. It is also a higher chance in getting a stroke, because improper flow of the blood can cause clots in the

The effects of a ligature around the AV groove presented no difference in the contraction of atria or ventricle after the first tightening. After the string was tightened further, the ventricular contractions were lost and the atria beat alone at 60 BPM. The AV signal between the chambers was blocked.

Atrial flutter is when the heartbeat is fast but regular. There are two types of atrial flutter:

Atril fibrillation, also known as Afib, causes problems with the heart's electrical impulse system resulting in an Afib irregular heartbeat. The most common type of heartbeat problem, Afib affects 2.2 million people in the United States.

Stroke was defined as the sudden onset of a focal neurologic deficit in a location associated with the area of a major cerebral artery. The primary safety outcome was major hemorrhage and was defined as a reduction in the hemoglobin level of at least 20 g/L, transfusion of at least 2 units of blood, or symptomatic bleeding in a critical organ or area. Results were calculated using the Cox proportional-hazards modeling. Systolic embolism or stroke occurred in 199 patients receiving warfarin, 182 patients receiving 110 mg of dabigatran twice daily, and in 134 patients receiving dabigatran 150 mg twice daily. Major bleeding events occurred in 3.36% of participants per year with warfarin, 2.71% per year in patients that received 110 mg of dabigatran, and 3.11% per year in those receiving 150 mg of dabigatran. From calculated data, results revealed that dabigatran administered at a dose of 110 mg twice daily was non-inferior to that of warfarin. Lower rates of stroke were associated with dabigatran administered at a dose of 150 mg twice daily compared with that of warfarin. For safety, it was concluded that the risk of bleeding was lowest with dabigatran 110mg twice daily, and was similar between dabigatran 150 mg twice daily and

There are many people that suffer from venous thromboembolism. Venous thromboembolism includes both deep vein thrombosis and pulmonary embolism. This is the third most common cause of vascular death after a myocardial infarction, also known as a heart attack, and stroke. This article examines the possibility of either full or low intensity anticoagulation therapy versus aspirin. This was a randomized study that consisted of 3,396 individuals who have venous thromboembolism. These individuals either received rivaroxaban, which is an anticoagulant, or 100 mg of aspirin once a day. The individuals in this study completed 6-12 months of anticoagulation therapy and were eligible for inclusion in the study if they were 18 years of age or older. The

When one begins to discuss issues that arise with an intrinsic organ, things get serious. Unfortunately, vital organs like the heart and liver that are causing problems can’t be removed like the appendix or the kidney and “cure” people of issues such as Appendicitis or constant dealings with gallstones. This is true when things begin to go awry within the heart and conditions begin to arise. Atrial Fibrillation (A-fib) is the most common type of arrhythmia, or issue with the heart rate or rhythm. Though A-fib is not a condition that is life-threatening, depending on the severity and lack of treatment, this condition leads to more serious issues like heart disease, and even heart attacks and strokes, which are usually what end up being the cause of death in individuals diagnosed with the condition. Because of A-fib leading to other more detrimental problems, such as the ones listed above, it is difficult to identify and pinpoint if someone has it or had it, which is why it is known as one of the contributors to the “silent killer,” also known as the heart attack. In this paper, gaining a deeper understanding of Atrial Fibrillation will be accomplished through the exploration of: causes, diagnosis, symptoms and treatment, the variation of types, what all is affected within the body as a result, what happens physically, and what occurs at the cellular level when diagnosed with this disorder. All in all, Atrial Fibrillation should be taken seriously and further research is

In the normal conduction of the heart the electrical impulse starts in the SA node, also called the pacemaker of the heart. The electrical impulse travels through the right atrium and through the Bachmann’s bundle into the left atrium. This stimulates the atria to contract. Next the signal travel to the AV node. The AV node slightly delays the signal. This delay is needed for the heart to beat properly. Without this delay the atria and ventricles would beat at the same time. The electrical signal then travels to the Bundle of His where it is split into the signals going to the right and left ventricle. The signal

The atria and ventricles are separated by valves known as the AV valves. The purpose of these valves is to prevent blood from flowing in the wrong direction. Following the movement of blood from the atrium, into the ventricle, the AV valve snaps shut which causes the first heart sound of the heart beat. The beat is caused by the closing of two other valves.

The research team hopes to use the numerical model they have designed to link modifications that take place at the cellular and tissue level when a heart fails to a numerically computed ECG. This, they wish, will assist to determine what it is that triggers ventricular fibrillation (VF), and to recognize the risk of VF.

Atrial Fibrillation (AFib) is the most common heart rhythm disorder in the US. More than three million people suffer from AFIb. Each year, approximately one hundred and twenty thousand Americans experience an ischemic stroke due to AFib. That accounts for more than 25% of all incidents of stroke from all causes. The incidence of stroke in people with AFib is five times higher than in those who do not have the ailment.

Atrial fibrillation (AF) is the most common sustained heart rhythm disturbance in the United States, affecting over 2 million individuals with over 150,000 new cases of AF being diagnosed each year. Approximately 4% of the population over the age of 65 is affected. As a person ages,

Today millions of Americans live or have lived with Atrial fibrillation. The main concern with this health issue is that many people who lived with it sometimes are not aware of it. Atrial fibrillation is defined by Mayo Clinic (2012) as “an irregular and often rapid heart rate that commonly causes poor blood flow to the body”. It occurs when the four chambers of the heart have a disrupted rhythm. The abnormal functionality of health may lead to a stroke because of the possible blood clot that will be formed. The Atrial fibrillation or Afib put the body in a situation without oxygen and nutrients because the body is not well supplied by a heart that is became weak. In general, only few people will feel change in their heartbeat. They may verbalize

Particularly heart beat irregularities (atrial fibrillation), disease of the heart valves, congestive heart failure or recent heart attack.

The heart is one of the most important organs in an organism’s body, no matter if they are aquatic, amphibian, or a mammal. This super organ works automatically, able to pump massive amounts of oxygen rich blood through the body by means of electrical impulses and the opening and closing of valves within its many layers. It is what keeps us and every other creature on this earth alive; so it is only natural for one to fear when there might be a problem with one’s heart. A cardiac arrhythmia can happen to anyone, no matter the age, race, or gender, and as such, doctors and scientist have spent years trying to better understand the heart and the way it functions so that they can try to prevent these problems and save millions of lives.
