Overview of Atrial Fibrillationafib

The Atrial Fibrillation (A-fib) can be described as an unsteady and frequently very fast heartbeat (arrhythmia) that could result in blood clots within the heart. A-fib Increases the risk of having a heart failure, stroke and heart-related problems. In the event of atrial fibrillation, the upper chambers of the heart (the Atria) beat in a chaotic and irregular manner in discord in the lower chambers (the ventricles) of the heart. For many people, A-fib There may be no signs. However, A-fib could cause a rapid heartbeat that is pounding (palpitations) or a breathing problems or weakness. Atrial fibrillation episodes can be intermittent or persist. Although A-fib It’s not a life-threatening condition however, it’s a serious medical issue that needs to be treated properly to avoid stroke. Treatment for atrial fibrillation can consist of medications, therapies to restore the heart’s rhythm, and catheter procedures to prevent the heart from sending out signals. Atrial fibrillation sufferers might also be suffering from a heart rhythm issue known as atrial flutter. Although atrial flutter can be an entirely different arrhythmia, its treatment is like that of atrial fibrillation.


A few people suffering from atrial fibrillation (A-fib) do not experience any signs or symptoms. If they do experience atrial fibrillation-related symptoms could have symptoms and signs such as:
  • Chest pain
  • Fatigue
  • Feelings of a rapid heartbeat that is fluttering, pounding or buzzing (palpitations)
  • Lightheadedness
  • Restricted capacity to exercise
  • Dizziness
  • Breathlessness
  • Weakness
Types of Atrial fibrillation:
  • Sometimes (paroxysmal atrial fibrillation). A-fib The symptoms are intermittent and last for short period of time to several hours. Sometimes , the symptoms can last longer than weeks and the episodes may be repeated. It is possible that symptoms will disappear by themselves. People who experience periodic A-fib require medical attention.
  • Persistent. When you have this kind of heart condition, heart rhythm isn’t able to return to normal in its own. If a person suffers from A-fib symptoms, treatments with medication can be utilized to ensure a regular heart rhythm.
  • Persistent and long-lasting. This type of atrial fibrillation is ongoing and lasts for longer than 12 months.
  • permanent. In this type of atrial fibrillation an irregular rhythm of the heart isn’t able to be corrected. Medicines are required to control the heart rate and keep blood clots out.


To better understand the reasons behind A-fib It can be useful to understand how the heart is beating. The heart is a typical structure with four chambers – two chambers in the upper (atria) as well as two chambers in the lower (ventricles). In the upper right-hand chamber within the heart (right atrium) is a set of cells known as”the sinus node.. The sinus node acts as the heart’s pacemaker. It generates the signal that triggers every heartbeat. In a normal heartbeat:
  • The signal originates through the sinus node to the two chambers of the upper heart (atria).
  • The signal travels through a passageway between the lower and upper chambers known as the atrioventricular (AV) node.
  • The signal’s movement triggers your heart to contract (contract) which then sends blood to your heart and your body.
In atrial fibrillation, signals within higher chambers in the heart become chaotic. This causes these chambers are shaken (quiver). The AV The node then gets bombarded by signals trying to make it to the lower chambers of the heart (ventricles). This can result in a fast and irregular heartbeat. The heart rate of patients with atrial fibrillation could vary from 100 to 175 beats per minute. The typical heart rate of 60-100 beats per minute.

Atrial fibrillation causes

Heart-related problems are the leading causes of atrial fibrillation. The causes that could cause atrial fibrillation are:
  • High blood pressure
  • Coronary arterial artery disease
  • Heart attack
  • Heart defect is present from birth (congenital heart defect)
  • Heart valve problems
  • Lung diseases
  • Physical stress from surgery, pneumonia or any other illness
  • Previous heart surgery
  • A problem with the heart’s naturally-generated rhythm maker (sick sinus syndrome)
  • Sleep Apnea
  • Thyroid disorders, such as hyperactive thyroid (hyperthyroidism) as well as other metabolic imbalances
  • In the use of stimulants, this includes certain drugs such as caffeine, tobacco, and alcohol
  • Viral infections
A few people with atrial fibrillation don’t have heart conditions or damage.

Risk factors

Factors that may raise the likelihood of developing atrial fibrillation (A-fib) are:
  • Age. The older a person gets, the greater the likelihood of developing atrial fibrillation.
  • The heart disease. Anyone with heart condition — such as heart valve issues congenital heart diseases, congestive heart failure and coronary artery diseases, or an history of heart attacks or heart surgery is more likely to develop atrial fibrillation.
  • Blood pressure is high. Having high blood pressure, especially when it’s not managed well by modifications to your lifestyle or medication that can raise the chance of developing atrial fibrillation.
  • The thyroid condition. In some people thyroid problems can cause heart rhythm issues (arrhythmias) which include atrial fibrillation.
  • Other health issues that are chronic. People with certain chronic diseases like metabolic syndrome, diabetes, chronic lung disease, kidney disease, sleep apnea or other respiratory conditions have an increased chance of developing atrial fibrillation.
  • Alcohol consumption. For some people drinking alcohol, it can cause an atrial fibrillation episode. Drinking in excess increases the chance of developing.
  • Obesity. People who have overweight are more at risk of developing atrial flutter.
  • Family background. An increased risk of atrial fibrillation can be found in certain families.


Blood clots can be a risky consequence of atrial fibrillation, which could lead to stroke. In atrial fibrillation, the erratic heartbeat can result in blood accumulating in the upper chambers of the heart (atria) and create blood clots. In the event that a blood-clot that forms in the left atrium (left atrium) is able to break free from the heart and travels to the brain and trigger stroke. The chance of suffering a stroke as a result of atrial fibrillation is higher as you age. Other medical conditions can increase the chance of having a stroke because of A-fib , including:
  • High blood pressure
  • Diabetes
  • Heart failure
  • A few heart diseases that are valvular
The use of blood thinners is commonly used to avoid blood clots and strokes for those suffering from atrial fibrillation.


A healthy lifestyle can help reduce the risk of developing heart disease and can help reduce the risk of atrial fibrillation. Here are some simple heart-healthy guidelines:
  • Eat a nutritious diet
  • Keep up your exercise routine and keep your weight in a healthy way
  • Don’t smoke
  • Reduce or eliminate alcohol consumption and caffeine
  • Be aware of stress levels, since intense anger and stress can lead to problems with the heartbeat.
