what is atrial fibrillation burden?

There are many ways one can define AF burden, such as the duration of the longest AF episode or number of AF episodes during a certain monitoring period. Intuitively, the best definition for AF burden is the proportion of time an individual is in AF during a monitoring period, expressed as a percentage.

The cause is not fully understood, but it tends to affect certain groups of people, such as those over 65. It may be triggered by certain situations, such as drinking too much alcohol or smoking. Atrial fibrillation can be defined in various ways, depending on the degree to which it affects you.

When AFib causes heart failure, fluid in the lungs can cause fatigue and shortness of breath. Oxygen-rich blood is not being delivered to the body and brain, causing physical and mental fatigue and reduced stamina.

Symptoms of atrial fibrillation The most obvious symptom of atrial fibrillation (AF) is palpitations caused by a fast and irregular heartbeat. A normal heart rate, when you are resting, should be between 60 and 100 beats a minute. In atrial fibrillation, it may be over 140 beats a minute.

Atrial fibrillation (also called AFib or AF) is a quivering or irregular heartbeat (arrhythmia) that can lead to blood clots, stroke, heart failure and other heart-related complications. At least 2.7 million Americans are living with AFib.

Some people who have atrial fibrillation have significant problems with their heart and with exercise, the heart rate can race tremendously during atrial fibrillation, thereby exacerbating the underlying heart condition and may lead to problems such as very low blood pressure, heart failure or a loss of consciousness.

Overall, atrial fibrillation leads to a turbulent and abnormal flow of blood through the heart chamber, decreasing the heart effectiveness to pump blood while increasing the likelihood of thrombus formation within the atria, most commonly the left atrial appendage. Triggers for AF include: Atrial ischemia. Inflammation.

Atrial fibrillation (AF) is a form of arrhythmia, or irregular heartbeat, in which the atria (the two small upper chambers of the heart) quiver instead of beating effectively. It is one of the most common forms of cardiac arrhythmia, affecting 0.4% of the general population and 5 to 10% of persons over 65 years of age.

Symptomatic AF was defined as the presence of one or more of the following symptoms: palpitations, syncope, dyspnea, chest pain, dizziness, and fatigue. Angina pectoris and symptoms of congestive heart failure, when described, were classified in the Euro Heart Survey as 'other symptoms' possibly related to AF.

Definition of lone atrial fibrillation This is a common but serious type of arrhythmia. It occurs when the heart's upper and lower chambers beat out of coordination. This causes poor blood flow and increases the risk of blood clots, stroke, and heart failure.

Silent AF is an asymptomatic form of AF incidentally diagnosed during a routine test or manifesting as an arrhythmia-related complication. Although recent trials have clearly demonstrated that patients with sub-clinical AF are at increased risk of stroke, the real incidence of this form of AF is still unknown.

Typically, afib is diagnosed by a simple EKG or ECG (electrocardiogram) where several electrodes are placed on your skin to measure and record your heart's electrical activity in wavelengths. It is painless and takes only a few minutes as you lie down for the test to be administered.

Abstract. Atrial fibrillation is the most common sustained arrhythmia, increases with age, and presents with a wide spectrum of symptoms and severity. Paroxysmal, persistent, and permanent forms require very individualized approaches to management.

Atrial Fibrillation Screening. Atrial fibrillation (Afib) is an irregular heartbeat (also known as arrhythmia) that occurs when the upper chambers of the heart (the atria) do not beat at a regular pace. They quiver, or fibrillate.

AFib may be brief, with symptoms that come and go. It is possible to have an atrial fibrillation episode that resolves on its own. Or, the condition may be persistent and require treatment. Sometimes AFib is permanent, and medicines or other treatments can't restore a normal heart rhythm.
