Palpitations
Noticeable fluttering, racing, or irregular beating in the chest.
Heart Rhythm Care
Atrial Fibrillation Treatment, Stroke Prevention, And Long-Term Rhythm Control
Atrial fibrillation, or AFib, is a common heart rhythm disorder that causes fast and irregular beating. It can raise the risk of stroke, heart failure, and fatigue, so early diagnosis and a clear treatment plan matter.

Clinical Overview
What Is Atrial Fibrillation?
The chaotic electric impulse in the upper chambers of the heart sets them into irregular and rapid pumping. This results in a fast and irregular heart rhythm in the range of 100 to 175 beats per minute. This speed causes the heart walls to quiver or fibrillate, known as atrial fibrillation or AFib.
AFib may be occasional or persistent. Some people notice only palpitations, while others have no symptoms until a routine ECG reveals the rhythm problem. Because AFib can increase the chance of stroke, management usually includes rate or rhythm control, blood-thinning treatment where appropriate, and regular follow-up.
Common triggers include high blood pressure, valve disease, thyroid disorders, alcohol excess, sleep apnea, heart failure, and age-related heart changes. Treating the cause and controlling the rhythm early helps reduce symptoms and long-term risk.
Common Warning Signs
Fatigue
Reduced energy or exercise capacity because the heart is not pumping efficiently.
Shortness of Breath
Breathlessness during normal activity or when lying down can point to AFib or related strain.
Dizziness / Weakness
Lightheadedness or near-fainting can happen when rhythm and blood flow are unstable.
Treatment And Stroke Prevention
Confirm Rhythm
ECG, Holter, and echo help confirm AFib and assess the heart structure.
Control Rate / Rhythm
Medicines or procedures are selected to stabilize pulse and relieve symptoms.
Reduce Stroke Risk
Blood thinner treatment may be needed depending on the individual risk profile.
Long-Term Follow-Up
Ongoing review ensures treatment remains effective and symptoms stay controlled.
Atrial Fibrillation Content
Atrial fibrillation is one of the most common heart rhythm disorders and can affect adults with high blood pressure, valve disease, heart failure, thyroid disease, or sleep apnea. Early detection helps reduce stroke risk, improve symptoms, and protect heart function.
Common Causes
High blood pressure, valve disease, diabetes, thyroid problems, alcohol excess, and heart muscle weakness.
When To Seek Help
Persistent palpitations, breathlessness, chest pain, dizziness, or fainting need prompt cardiology review.
Prevention Tips
Control risk factors, maintain healthy weight, avoid smoking, sleep well, and follow medicine schedules.
Frequently Asked Questions
Is atrial fibrillation dangerous?
Yes, because it can increase the risk of stroke and heart failure if not treated properly. Many patients do well with timely care and follow-up.
Can AFib be cured?
Some patients can have long-term control or rhythm restoration, while others need ongoing management. The best approach depends on the cause and the individual heart condition.
What tests are used for AFib diagnosis?
ECG, Holter monitoring, echocardiography, and blood tests are commonly used to diagnose and plan treatment.
