If you are diagnosed with atrial fibrillation, you are in good company. In fact, there are a number of famous figures who have been diagnosed with the condition.
In a person with atrial fibrillation, the heart rate can exceed 100 beats per minute, sometimes by quite a long way.
However, atrial flutter is less common than atrial fibrillation and the heart rhythm tends to be more organized and less chaotic.
According to his medical records, President Joe Biden has experienced periods of atrial fibrillation since having his gall bladder removed in 2003.
Biden is joined by former UK Prime Minister Tony Blair, as well as other celebs such as Howie Mandel and Barry Manilow, in the list of famous people with this common heart condition.

People who are treated with catheter ablation may need to have a pacemaker fitted afterwards to help their heart beat regularly.
And, finally, with catheter ablation the area inside the heart that is causing the abnormal rhythm is destroyed using radio frequency energy.
In cardioversion, the patient is given a controlled electric shock in order to restore the heart's natural rhythm.
There are also medicines that are sometimes prescribed to help control the heart rate or rhythm.
People with atrial fibrillation may also have atrial flutter. The two conditions are similar in that they share symptoms, causes, and possible complications.
Treatment is often aimed at preventing strokes (since people with atrial fibrillation are at higher risk of having a stroke).
And finally there’s long-standing atrial fibrillation, which we normally associate with a person who has had the condition for more than a year.
While it may sound quite alarming, atrial fibrillation is in fact very common. For example, it affects around 1.4 million people in the UK alone.
The condition can affect adults of any age, although it is more common in older people and it’s more likely to affect men than women.
There are various ways to define atrial fibrillation, depending on how it affects you. In paroxysmal atrial fibrillation, episodes come and go and they usually clear up on their own within 48 hours.
With persistent atrial fibrillation, episodes tend to last longer than seven days (although they may be shorter if the patient is treated).
Older people and people living with long-term (chronic) conditions such as heart disease, high blood pressure, or obesity appear to be at higher risk.
These are symptoms of a heart attack; anyone experiencing them requires immediate and urgent medical attention.
You should call emergency services if you have sudden chest pain that spreads to your arms, back, neck, or jaw, makes your chest feel tight or heavy, also started with shortness of breath, sweating, and feeling or being sick, or lasts more than 15 minutes.
It is not known exactly what causes atrial fibrillation, but it does seem to affect certain groups of people more than others.
It is important that you see a doctor if you have chest pain that comes and goes, chest pain that goes away quickly but is still worrying, or you notice a sudden change in your heartbeat.
People with atrial fibrillation might also notice palpitations, sometimes in episodes that can last as long as a few minutes.
While atrial fibrillation is sometimes symptomless and certain sufferers don’t know they have it, it can also cause dizziness, shortness of breath, and tiredness.
Equally, it is important to seek medical advice if your heart rate is consistently lower than 60 or above 100 (particularly if you’re also experiencing other symptoms such as dizziness or shortness of breath).
A normal, healthy heartbeat should be regular, and it usually sits somewhere between 60 and 100 beats per minute.
For those of you who have never heard of the term, atrial fibrillation is a heart condition that causes an irregular and abnormally fast heartbeat.
If there is no one in your immediate circle who has been diagnosed with atrial fibrillation, you'd be forgiven for not knowing what it was. One of the lesser-discussed heart conditions, atrial fibrillation causes the heart to beat irregularly and abnormally fast. And while awareness of atrial fibrillation is low, it is in fact quite common. There are even some quite famous faces who have been diagnosed with the condition.
