what is chronic atrial fibrillation?
148797
Overview. Atrial fibrillation (AFib) is a type of heart arrhythmia that causes the top chambers of your heart, the atria, to quiver and beat irregularly. AFib used to be described as chronic or acute, with chronic AFib lasting longer than one week.

Paroxysmal AF (PAF), also termed intermittent AF, is defined as an episode of AF that terminates spontaneously or with intervention in less than seven days [4]. "Persistent," "longstanding persistent," and "permanent" are clinical labels used for the other types of AF. (See "Overview of atrial fibrillation".)

Atrial fibrillation (also called AF or Afib) is a type of arrhythmia. In atrial fibrillation, abnormal electrical activity in the top chambers of the heart overwhelms the heart's own pacemaker (part of its electrical system) and the conduction messages become chaotic.

Definition. Atrial fibrillation (AF) is a common heart rhythm disorder caused by degeneration of the electrical impulses in the upper cardiac chambers (atria) resulting in a change from an organized heart rhythm to a rapid, chaotic rhythm.

What is ablation for atrial fibrillation? Ablation is a procedure to treat atrial fibrillation. It uses small burns or freezes to cause some scarring on the inside of the heart to help break up the electrical signals that cause irregular heartbeats. This can help the heart maintain a normal heart rhythm.

Although atrial fibrillation itself usually isn't life-threatening, it is a serious medical condition that sometimes requires emergency treatment. A major concern with atrial fibrillation is the potential to develop blood clots within the upper chambers of the heart.

In atrial fibrillation, the atria beat irregularly. In atrial flutter, the atria beat regularly, but faster than usual and more often than the ventricles, so you may have four atrial beats to every one ventricular beat.

Afib with RVR refers to atrial fibrillation with rapid ventricular rate. Usually the heart is like clockwork, the top (collecting) chambers beat then the bottom (main pumping) chambers sense this and also beat, and so on, in a nice regular fashion just like a clock ticking second after second.

In atrial fibrillation, the atria beat irregularly. In atrial flutter, the atria beat regularly, but faster than usual and more often than the ventricles, so you may have four atrial beats to every one ventricular beat. Atrial flutter is less common than atrial fibrillation.

Around a third of people with atrial flutter also have atrial fibrillation. Atrial flutter is similar to atrial fibrillation, but the rhythm in the atria is more organised and less chaotic than the abnormal patterns caused by atrial fibrillation. Treatment for atrial flutter is also slightly different.

During atrial fibrillation, the heart's two upper chambers (the atria) beat chaotically and irregularly — out of coordination with the two lower chambers (the ventricles) of the heart. Atrial fibrillation symptoms often include heart palpitations, shortness of breath and weakness.

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.

2. Persistent atrial fibrillation lasts longer than seven days. Symptoms can be the same as with paroxysmal atrial fibrillation. Treatment is needed with this type of atrial fibrillation as heart rhythm doesn't return to normal by itself.

By not getting enough oxygen to the body, afib can lead to heart and valve diseases, sleep apnea, and chronic fatigue. In addition, atrial fibrillation can lead to two potentially life-threatening conditions, congestive heart failure and stroke.

Atrial fibrillation (AF), an electrical disorder of the heart rhythm, is the most common pathological arrhythmia in horses. With this condition, the atria fail to contract but instead quiver or fibrillate, and impulses are conducted intermittently through the atrioventricular (A-V) node to the ventricles.

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.

Persistent AFib is defined by an episode that lasts longer than 7 days. It doesn't stop without treatment. Normal rhythm may be achieved with medications or electric shock treatment. Chronic, or permanent, AFib may be ongoing for many years.
