is there a difference between atrial fibrillation and tachycardia?
284058
Atrial fibrillation is another type of atrial tachycardia that is closely related to atrial flutter. However, the arrhythmia that occurs in AFib is much more chaotic and results in a fast and usually very irregular heart rhythm or a atypical and irregular ventricular rate that can effect heart health.

Atrial flutter and atrial fibrillation are both abnormal heart rhythms. They occur when there is an issue with the electrical signals and pathways in your heart, which usually help it beat in an organised, effective way. Normally, the top chambers (atria) contract and push blood into the bottom chambers (ventricles).

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.

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.

These waves are a sign of the atria pulsing out of time. Fibrillatory waves can look a lot like P waves, and this can make an A-fib rhythm look like sinus rhythm. However, an A-fib rhythm is usually irregular while sinus rhythm is consistent and even.

Common types of tachycardia include: Atrial fibrillation. Atrial fibrillation is a rapid heart rate caused by chaotic, irregular electrical impulses in the upper chambers of the heart (atria). These signals result in rapid, uncoordinated, weak contractions of the atria.

Atrial fibrillation is a heart condition that causes an irregular and often abnormally fast heart rate. A normal heart rate should be regular and between 60 and 100 beats a minute when you're resting. You can measure your heart rate by feeling the pulse in your neck or wrist.

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.

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.

A: It is not uncommon for atrial fibrillation (AFib) to occur at night. The nerves that control the heart rate typically are in sleep mode, and resting heart rate drops. Under these conditions, pacemaker activity from areas other than the normal pacemaker in the heart can trigger the onset of AFib.

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.

Normally, the top chambers (atria) contract and push blood into the bottom chambers (ventricles). 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.

Tachycardia is a fast or irregular heart rhythm, usually more than 100 beats per minute and as many as 400 beats per minute. At these elevated rates, the heart is not able to efficiently pump oxygen-rich blood to your body.

On an ECG (EKG), atrial fibrillation is characterized by absence of P-waves and irregular narrow QRS complexes. Reminder: P-wave represents electrical activity of the SA node that is now obscured by activities of multiple ectopic sites.

Any of these may cause the heart to skip a beat, beat too fast, or beat too slow. 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.

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.
