are arrhythmia and afib the same thing?

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.

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.

There is no agreement on the definition of atrial fibrillation (AF) with a slow ventricular response: the condition may be characterized as an AF with slow resting heart rate or as an AF with normal resting heart rate but with prolonged ventricular pauses.

The most common tachyarrhythmias are atrial fibrillation or flutter with rapid ventricular response. These tachyarrhythmias are more common in older patients with advanced sinoatrial nodal disease in whom sinoatrial node fibrosis may favor reentrant beats or tachycardia.

Atrial fibrillation, also known as A-fib, is the most common form of arrhythmia, which is a condition where a person experiences heart rhythm problems. Paroxysmal atrial fibrillation occurs when a rapid, erratic heart rate begins suddenly and then stops on its own within 7 days.

Can Atrial Fibrillation Be Cured? Home | Can Atrial Fibrillation Be Cured? While medications and electrical cardioversion are common for atrial fibrillation treatment, they don't cure afib. There are two major approaches to consider if medications aren't working for you.

Paroxysmal AFib are episodes of AFib that occur occasionally and usually stop spontaneously. Episodes can last a few seconds, hours or a few days before stopping and returning to normal sinus rhythm, which is the heart's normal rhythm. Some people may have single episodes of AFib.

Other types of AFib are: paroxysmal: AFib that's intermittent and lasts less than one week. persistent: AFib that's continuous for more than one week but no more than 12 months. permanent: AFib that's continuous and does not respond to treatment.

Heart disease: Some types of heart disease, such as high blood pressure, are risk factors for AFib, which is a type of arrhythmia. Scarring or abnormal tissue deposits can also cause bradycardia (slow heart rate) or tachycardia (rapid heart rate) by interfering with the heart's electrical system.

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.

Atrial flutter is a type of atrial tachycardia that results in an arrhythmia (rhythm disorder or not a normal rhythm) where the atria of the heart beat too quickly in a fast, usually regular, rhythm. Atrial fibrillation is another type of atrial tachycardia that is closely related to atrial flutter.

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.

Atrial fibrillation happens when electrical impulses fire off from different places in the top chambers of the heart (the atria) in a disorganised way. These irregular impulses cause the atria to quiver or twitch, which is known as fibrillation. This causes as an irregular, and sometimes fast, heartbeat or pulse.

Fact: Atrial fibrillation is almost always a recurring disease and lifelong treatment is needed to minimize symptoms and to avoid stroke and heart failure. Early on, episodes of Afib tend to be sporadic and self terminating.

Atrial tachycardia (AT) is a type of abnormal heart rhythm, or arrhythmia. It occurs when the electrical signal that controls the heartbeat starts from an unusual location in the upper chambers (atria) and rapidly repeats, causing the atria to beat too quickly.
129865
Supraventricular tachycardia (SVT) is a faster than normal heart rate above the ventricles, which can cause the atria to beat between 100 - 300 beats per minute. Atrial fibrillation (afib) is when the atria of the heart flutter or shiver rather than fully contract.

What Is an Arrhythmia? An arrhythmia is an uneven heartbeat. It means your heart is out of its usual rhythm. It may feel like your heart skipped a beat, added a beat, or is "fluttering." It might feel like it's beating too fast (which doctors call tachycardia) or too slow (called bradycardia).
