Overview

Atrial fibrillation is a heart condition characterised by an irregular heartbeat. It occurs when the upper chambers of the heartbeat are out of sync with the lower chambers. While some individuals with AFib may not experience any noticeable symptoms, others may have early signs that can indicate the presence of the condition. The early symptoms of atrial fibrillation may include shortness of breath, fatigue and dizziness.

Let us look at early symptoms of atrial fibrillation that can help in early diagnosis and prompt treatment.

Early Symptoms of Atrial Fibrillation

Below are some early symptoms of atrial fibrillation; it will help in identifying the disease early.

- Palpitations- One of the most noticeable symptoms is a rapid, irregular or pounding heartbeat. In this situation, the affected person may feel a fluttering of heart, racing or skipping beats. It can be persistent or it can come and go.
- Fatigue and Weakness- Atrial fibrillation causes a sense of weakness due to irregular heartbeats. This happens when the heart is unable to pump blood efficiently, which leads to a reduction of oxygen reaching the body’s tissue and organs.
- Shortness of breath- It occurs when the person finds breathing difficult. It takes place, especially during physical exertion. The irregularity of the heart rhythm can impair the heart’s ability to pump blood effectively which results in inadequate oxygen supply to the body.
- Dizziness and Lightheadedness-Experiencing a sensation of unsteadiness, feeling dizzy, and lightheaded can occur with atrial fibrillation. This is caused due to the irregularity of heartbeats.
- Chest Pain- Individuals suffering from Atrial fibrillation may experience chest pain or discomfort. However, you must understand that the chest pain associated with atrial fibrillation is generally not severe or prolonged as that of a heart attack.
- Fainting- In some cases when the heart rate becomes extremely rapid, atrial fibrillation can cause fainting spells or loss of consciousness. This particular symptom of AFib needs to be treated quickly with expert medical attention.
- Exercise intolerance- If you find it increasingly difficult to engage in physical activities or your tolerance for exercise has significantly decreased, it may be a sign of AFib.

It is important to note that these symptoms can be caused by various other conditions as well. If a person experiences any of these symptoms or suspects he or she may have AFib, it is advisable to consult a healthcare professional for a proper evaluation and diagnosis.

Types of Atrial Fibrillation

Atrial Fibrillation is classified into different types which are based on the duration and pattern of irregular heart rhythm. Let us understand the different types of AFib.

Paroxysmal Atrial Fibrillation:

It refers to irregular heart rhythms which may start suddenly and get resolved on their own within 7 days, and as early as 48 hours. This can last for seconds, minutes and hours. A person suffering from paroxysmal atrial fibrillation may experience symptoms intermittently or may be completely asymptomatic between the occurrence.

Persistent Atrial Fibrillation:

Persistent Atrial Fibrillation occurs when irregular heart rhythms last for more than 7 days. In this type, medical intervention is required to restore the normal rhythm. This treatment may require medications, electrical cardioversion or other ways to restore the normal rhythm of the heartbeat.

Long-lasting Persistent Atrial Fibrillation:

This type of AFib refers to a sustained irregular heart rhythm that lasts longer than a period of 12 months. This kind of atrial fibrillation is usually more challenging to treat and it requires a complete set of different treatment strategies, a combination of medication and cardioversion.

Permanent Atrial Fibrillation:

Permanent AFib is a situation in which the efforts to restore normal sinus rhythm are no longer successful. The irregularity of heart rhythm becomes a long-term condition. In this condition, medications are used to control the symptoms and reduce the heart rate.

Nonvalvular Atrial Fibrillation:

Nonvalvular AFib refers to a situation in which the irregular heart rhythm is not associated with significant heart valve problems, such as mitral valve stenosis or mechanical heart valve replacement. This condition is the most common of them all.

Valvular Atrial Fibrillation:

Valvular AFib occurs in individuals with underlying heart valve disease, like mitral valve stenosis or regurgitation. The presence of valve abnormalities may complicate the management of AFib and special treatment and medications are required.

Difference between Heart Attack and Atrial Fibrillation

Heart attack and Atrial Fibrillation are two distinct medical conditions that affect the heart, but the causes, symptoms and implications are different. Here are some key differences between both of them.

Cause:

- Heart Attack: It occurs when there is a blockage in one or more of the coronary arteries that supply blood to the heart muscle.
- AFib: It is an abnormal heart rhythm characterised by chaotic electrical signals in the upper chamber of the heart. It is primarily caused by problems with the heart’s electrical system.

Condition:

- Heart Attack: A heart attack is a sudden and acute incident when there is a lack of blood flow and oxygen to a portion of the heart muscle.
- AFib: AFib is a chronic condition which is characterised by irregular and rapid heart rhythm.

Symptoms:

- Heart Attack: Chest pain or discomfort, shortness of breath, nausea and cold sweats.
- AFib: Pounding heartbeat, fatigue, weakness, shortness of breath, lightheadedness and fainting.

When to Consult a Doctor

You can also get in touch with the expert cardiology doctors at Narayana Healthcare based in your city to get immediate attention and medical support during injuries, health disorders or any other health concern.

Conclusion

Atrial Fibrillation is a heart disorder involving issues in sleeping and irregular heartbeat rate while sleeping. Although detecting this early and maintaining proper medications can help reduce the risk of severe consequences.

FAQs:

Q. What is Atrial Fibrillation? A. Atrial fibrillation is a disease that results in an irregular heartbeat in the affected person. It occurs when the upper chambers and lower chambers of the heart beat without synchronisation with each other.

Q. What are the causes of atrial fibrillation? A. There are different causes of this disease which include excessive use of alcohol, usage of drugs, sleep apnea, and family history. One of the most prominent reasons is chronic conditions.

Q. How many types of Atrial fibrillation are there? A. There are 4 types of atrial fibrillation: Occasional, Persistent, Long-standing and Permanent.

Q. What are the complications of Atrial fibrillation? A. There are 2 significant complications of atrial fibrillation: increased chances of heart stroke and heart failure.
