Atrial Fibrillation

Atrial Fibrillation Assignment Hel

Atrial fibrillation is an irregular and frequently rapid heart rate that usually causes poor blood circulation to the body.

A person may develop atrial fibrillation that may need treatment and does not go away. Although atrial fibrillation itself is not life threatening,however, it is a serious medical condition that occasionally needs emergency treatment, as it may cause complications.

Treatments for atrial fibrillation may contain other interventions and drugs to attempt to change the electrical system of the heart. Atrial fibrillation or AF is the most frequent form of arrhythmia (ah-RITH-me-ah). An arrhythmia is an issue with the speed or rhythm of the pulse. During an arrhythmia, the heart cannot beat too slow or with an unusual rhythm.

The term “fibrillate” means to contract extremely fast and irregularly.
In the atria, blood pools in AF. Consequently, the upper and lower chambers of the heart do not work together as they should.

Therefore, even when AF is not found, it can raise the risk of stroke. In many people, AF can cause heart failure or chest pain, particularly when the heart rhythm is quite fast.

AF may occur infrequently or every now and then, or it might become an on-going or long-term heart difficulty that continues for years.It is helpful to get the internal electrical system of the heart in order to comprehend AF. The heart’s electrical system controls the speed and rhythm of the pulse.

With each pulse, an electric signal propagates to the underside from the top of the heart. It causes the heart as the signal goes.
Each electric signal starts in several cells which are known as the sinus node or senatorial (SA) node. The SA node is situated in the right atrium. (This speed might be slower in quite healthy athletes.)
From the SA node, the electric signal goes throughout the left and right atria. It causes the atria.
The electric signal then goes down to several cells which is known as the atrioventricular (AV) node, situated between the atria and the ventricles. Here, the sign slows down somewhat, letting the ventricles time to end filling with blood.

The electric signal journeys to the ventricles and then leaves the AV node. The ventricles then loosen, and the pulse procedure starts again in the SA node.

In AF, the heart’s electrical signals do not start in the SA node. They start in the pulmonary veins,which are nearby or in a different section of the atria. They may propagate through the atria in a fast or disorganized manner. As a result, this could create atria.

The AV node floods with electric nerve impulses. Consequently, the ventricles start to beat extremely fast. However, the signals cannot be sent by the AV node to the ventricles as quickly as they arrive. So, although the ventricles are beating quicker than normal, they are not beating as quickly as the atria.

Therefore, ventricles and the atria beat in a unified manner. This creates a rapid and irregular heart rhythm.
Blood is not pumped into the ventricles as nicely as it should be. In addition, the quantity of blood pumped to the body out of the ventricles is dependent on the arbitrary atrial beats.
The body could get occasional bigger and little levels of blood.

The symptoms are minimized if the heart rate slows.AF finishes independently and may be short with symptoms that come and go. On the other hand, this condition needs treatment and it could be on-going. AF is a long-term and alternative treatments or medications which cannot restore a regular heart rhythm.

Atrial fibrillation is an irregular pulse that raises the danger of cardiovascular as well as stroke disease. Indications include weakness, dizziness, and exhaustion. The treatment includes processes such as cardio version, ablation, pacemakers, operation, and at times drugs and lifestyle changes.

Generally, the heart relaxes and contracts to a regular beat.
This clot risk is patients with this particular illness that are put on blood thinners. Individuals with atrial fibrillation have a heightened stroke risk of about five percent per year.”

The heart has four areas or chambers. It is directed by the electrical system of the heart.
The electrical impulse starts in an area, which is known as the sinus node that is situated in the right atrium.
Subsequently the electric nerve impulses go in an orderly manner to the areas which are known as the atrioventricular (AV) node and HIS-Purkinje network. The AV node is the electric bridge that enables the nerve impulse to go to the ventricles from the atria. HIS-Purkinje network carries the nerve impulses through the ventricles. This can force the blood to the lungs as well as the body out of the heart. Oxygenated blood empties from the lungs to the left atrium. A regular pulses in a steady rhythm about 60 to 100 times per minute at rest.

A person may have atrial fibrillation without needing any symptoms whatsoever. In case one has the symptoms, then it may contain:

— Heart palpitations (a sudden pounding, fluttering, or racing sensation in the torso)
— Fatigue or deficiency of energy
— Dizziness (feeling faint or lightheaded)
— Shortness of breath (trouble breathing during regular tasks or even at rest)

Generally, the muscular walls contract (tighten and compress) to force blood outside and across the body. Then they loosen or the heart can fill with blood. This procedure is repeated every time the pulses.

In atrial fibrillation, the heart’s upper chambers (atria) contract at random and at times the heart muscle cannot relax correctly between contractions. This reduces the efficiency and functionality of the heart.

The heart’s natural pacemaker, which can restrain the rhythm of the heart, is overridden by these nerve impulses. This causes one to get a highly unusual pulse rate.The cause is not completely comprehended; however it tends to happen in specific groups of individuals and it may be activated by specific scenarios such as drinking excessive quantities of alcohol or smoking.
