can atrial fibrillation have a regular rhythm?

When the atrial rhythm is fibril- lation, the presence of a regular ven- tricular rhythm suggests that a junc- tional pacemaker may be responsible for the impulses that are conducted to the ventricle. When the ventricu- lar rate is very slow, complete AV block is usually thought to be present.

Episodes of atrial fibrillation may come and go, or you may develop atrial fibrillation that doesn't go away and may require treatment. Although atrial fibrillation itself usually isn't life-threatening, it is a serious medical condition that sometimes requires emergency treatment.

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.

The most obvious symptom of atrial fibrillation is heart palpitations – where the heart feels like it's pounding, fluttering or beating irregularly, often for a few seconds or possibly a few minutes.

For example, AF can manifest with a regular ventricular response in the presence of AV block or with a ventricular paced rhythm. A 12-lead ECG is best to establish the diagnosis of AF.

Paroxysmal atrial fibrillation occurs when a rapid, erratic heart rate begins suddenly and then stops on its own within 7 days. It is also known as intermittent A-fib and often lasts for less than 24 hours. The American Heart Association (AHA) estimate that 2.7 million American people live with some form of A-fib.

PACs and SVTs may (or may not) act as triggers that can initiate episodes of atrial fibrillation or atrial flutter. As PVCs occur in the ventricular chambers of the heart, they cannot directly initiate an episode of atrial arrhythmia.

Atrial fibrillation (AF or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by the rapid and irregular beating of the atrial chambers of the heart. It often begins as short periods of abnormal beating, which become longer or continuous over time.

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.

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.

It's different from atrial fibrillation, because the heart rhythm in atrial flutter is regular, not chaotic. It is the second most common tachyarrhythmia, or fast heart rhythm disorder. Often, atrial flutter and atrial fibrillation occur at the same time.

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.

If unchecked, an irregular or racing heartbeat could contribute to problems, including premature death. One such condition where your heart can beat out of rhythm is called atrial fibrillation. Pericarditis, an inflammation around the heart, could cause atrial fibrillation.

Atrial fibrillation is detected and diagnosed as the result of a test called an electrocardiogram (ECG or EKG) that records the heart's electrical activity. Because Atrial fibrillation occurs irregularly, the short ECG a doctor would typically perform in-office is unlikely to detect it.

For example: paroxysmal atrial fibrillation – episodes come and go, and usually stop within 48 hours without any treatment. persistent atrial fibrillation – each episode lasts for longer than 7 days (or less when it's treated)

How atrial fibrillation feels varies from person to person. Some patients notice palpitations and irregular heartbeats and are immediately aware when atrial fibrillation starts. Others feel chest discomfort, shortness of breath, lightheadness, dizziness or a general tiredness, without having palpitations.

Ideally, to treat atrial fibrillation, the heart rate and rhythm are reset to normal. To correct your condition, doctors may be able to reset your heart to its regular rhythm (sinus rhythm) using a procedure called cardioversion, depending on the underlying cause of atrial fibrillation and how long you've had it.
