Atrial fibrillation: what are the causes, symptoms and consequences


Atrial fibrillation is the most common form of cardiac arrhythmia. Let’s find out what are the causes, the most common symptoms and the consequences that can arise.

When we talk about atrial fibrillation we mean the presence of uncoordinated cardiac activity, usually too fast and not very effective . A decompensation that affects 1% of the population and that tends to increase its incidence with advancing age, reaching a good 6%.

Of various types, atrial fibrillation can have different causes and in certain cases can lead to consequences such as a more rapid deterioration of the heart. So let’s try to get to know this problem better by learning to recognize its symptoms.

Atrial fibrillation: the most common causes that are good to know

Atrial arrhythmia can have various causes. Sometimes it occurs as a result of heart disease such as myocarditis or congenital heart disease.


In other cases it can develop due to an incorrect work by the thyroid gland or in the presence of hypertension .
Under certain circumstances it can also be caused by certain medications or occur after heart surgery. At the same time, there are situations in which tracing a precise cause is really difficult.

In this regard, it is important to know that cardiac fibrillation can be of different types: such as paroxysmal atrial fibrillation which occurs only in a few short episodes that resolve spontaneously, or the persistent one which lasts longer and therefore requires the medical intervention and finally there is the chronic one which tends to remain stable over time.

Atrial fibrillation: the most common symptoms

Going to the symptoms of atrial fibrillation, the most common are:

– Accelerated heartbeat.
– Chest pain.
Tiredness .
– Difficulty in breathing.
– Heart failure.
– Gastric disorders with a swollen belly.
– Pulmonary edema.

In case of problems with heart rate acceleration that does not return spontaneously or pain or other symptoms it is therefore very important to consult a doctor immediately or, depending on the severity, go to the emergency room.

In any case, even when the arrhythmia returns on its own it is very important to talk about it with your doctor in order to carry out specific control tests such as, for example, the electrocardiogram. A simple and non-invasive way to understand if you suffer from arrhythmia.
