atrial fibrillation definition. a supraventricular tachyarrhythmia defined by rapid, irregular atrial activation. -->loss of coordinated atrial contraction. -->irregular electrical input to the AV node typically leads to sporadic ventricular contraction rate.

When your heartbeat returns to normal within 7 days, on its own or with treatment, it's known as paroxysmal atrial fibrillation. It can happen a few times a year or as often as every day. It often becomes a permanent condition that needs regular treatment.

Atrial fibrillation is an irregular and often rapid heart rate that occurs when the two upper chambers of your heart experience chaotic electrical signals. The result is a fast and irregular heart rhythm. The heart rate in atrial fibrillation may range from 100 to 175 beats a minute.

People who binge drink alcohol, or drink excessively, may experience atrial fibrillation, or AFib. Atrial fibrillation, or AFib, is a heartbeat that is fast and often irregular. While treatable, it is a severe condition because it may lead to complications like blood clots, heart failure, and stroke.

Vagal vs. There's vagal atrial fibrillation and there's adrenergic atrial fibrillation. Vagal afib is afib that occurs mostly at night during sleep, after a meal, or when you're resting after exercise. Adrenergic afib is afib that's mostly triggered by exercise, stress, stimulants, and exertion.

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.

Atrial fibrillation and alcohol Drinking excessive amounts of alcohol can trigger atrial fibrillation – a type of irregular heartbeat. Atrial fibrillation increases your risk of stroke by five times, because it can cause blood clots to form in the heart. If these clots move up into the brain, it can lead to stroke.

Atrial fibrillation (AFib) is a type of heart disorder marked by an irregular or rapid heartbeat. Persistent AFib is one of three main types of the condition. In persistent AFib, your symptoms last longer than seven days, and your heart's rhythm isn't able to regulate itself anymore.

Abstract. Atrial fibrillation (AF) is a significant cause of morbidity and health care expenditures. Patients with AF suffer a variety of symptoms including chest pain, palpitations, shortness of breath, and fatigue. Some patients have no symptoms, a condition referred to as asymptomatic or "silent" AF.

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.

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.

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 flutter (AFL) is a type of abnormal heart rate, or arrhythmia. It occurs when the upper chambers of your heart beat too fast. When the chambers in the top of your heart (atria) beat faster than the bottom ones (ventricles), it causes your heart rhythm to be out of sync.

Atrial Fibrillation and Wolff-Parkinson-White Syndrome (WPW) Atrial fibrillation is a medical emergency when rapid antegrade conduction over an accessory pathway occurs in Wolff-Parkinson-White syndrome.

Those who do have atrial fibrillation symptoms may experience signs and symptoms such as: Palpitations, which are sensations of a racing, uncomfortable, irregular heartbeat or a flip-flopping in your chest. Weakness. Reduced ability to exercise.

What causes atrial fibrillation? Sometimes the cause of AFib is unknown. Other times, it is the result of damage to the heart's electrical system from other conditions, such as longstanding, uncontrolled high blood pressure or coronary artery disease. AFib is also the most common complication after heart surgery.

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.
