What is atrial fibrilation?

he heart is a pump dispersing blood to the body. It’s 4 chambers. The atria accumulate blood into the heart through the veins and using a gentle contraction fill the ventricles of the heart. The ventricles pump blood from the heart through the blood vessels, this output signal is in rest approximately 4 to 5 liters per minute. With every beat the ventricle sends blood into the lungs along with the ventricle that is larger sends blood into each member of the human anatomy.

The heart’s primary electrical controller, the’pacemaker’ is a set of cells known as the”sinus node”. It sends the typical regular electric signal that’s transmitted throughout the atria and then to the ventricles through the heart’s most important relay channel the”atrio-ventricular node”. This system of transmission makes the heart muscles contract so the first squeeze blood into the ventricle and the ventricles pump blood into the blood vessels and the entire body.

Usually there are 4 of them, 2 in the ideal lung and two from the lung. The region of their intersection with the left atrium has strange properties that’s been demonstrated to trigger atrial fibrillation. That is exactly why this component of the pulmonary veins are the goal for treatments like ablation.

Atrial fibrillation is a condition which makes the heart beat irregularly unlike the standard heartbeat that’s regular. The best chambers of the heart”that the atria” quiver in a really quick and disorderly routine so blood circulation slows down or stagnates. The main pumping chambers”the ventricles” also beat irregularly so they don’t induce blood around the entire body as economically.

Atrial fibrillation signifies a problem with the heart’s electrics. A fantastic analogy for that is that the motion of water in a pond. A ripple that is fantastic moves across the pond, if you drop a rock. From the pacemaker throughout the atria into the ventricles, during a rhythm, power spreads in exactly the exact same manner. You get straightened waves Should you fall stones . This is similar to the waves from atrial fibrillation, which provide the heart its pumping.

Do the heart’s electrics error similar to this? We don’t fully comprehend why but several distinct ailments (Table 1) also harm the heart’s electrical properties and might cause atrial fibrillation. These ailments include not just ailments limited to the heart but also other disease such as diabetes. Atrial fibrillation may occur without a detectable or known heart disease. The heart cells found in which the pulmonary veins combine the atria are especially vulnerable to acting electrically abnormally. The pulmonary veins afterward are frequently the origin generating atrial fibrillation.

Acute reversible Problems

Chronic Ailments

Pulmonary embolism
(Sudden blockage in a lung artery from blood clot)

Heart assault Pneumonia
(disease of one or both lungs)Heart collapse
Pericardial effusion

Chronic alcohol abuse


ThyrotoxicosisObstructive sleep apnoea
(cessation of airflow during sleep preventing oxygen from getting into the lungs brought on by obstruction of the upper airways)Obesity
(excess body fat using negative consequences on health)
If atrial fibrillation ceases within a brief while, then it’s known as paroxysmal however in case your atrial fibrillation is present continuously or lasts for prolonged intervals then it’s persistent. These conditions are significant as they’re significant elements in selecting your own suitability for the treatments. When regular heart rhythm cannot be revived your atrial fibrillation is termed permanent (Table 2).

  • Paroxysmal
  • Persistent
  • An episode of atrial fibrillation lasting more than
  • An episode of atrial fibrillation lasting more than 1


When no effort is made or it’s not feasible to restore normal (sinus) rhythm.

Atrial fibrillation is your commonest abnormal heart rhythm also it’s found in about 1 percent of the populace. As we age, It’s considerably more common. It’s seen in 5 percent of those over age 65 and 10 percent of the over 80 although uncommon in people.

There are a range of medical ailments that raise the danger of developing atrial fibrillation throughout your lifetime (table 1). Every ailment that increases the pressure on the heart was associated with atrial fibrillation.

Obstructive sleep apnoea is a state where during sleep the muscles in the throat relax causing blockage of their airway. You are inclined to snore spouses and loudly explain you stopping breathing or gasping for air. This starvation of oxygen is bad for your heart and atrial fibrillation may result. Obesity has also been recognised to raise the risk of atrial fibrillation.

It is important to recognise these conditions favouring atrial fibrillation they may be treated. This might be as important as healing the atrial fibrillation itself. However
