Arrhythmia characterized by irregular, disorganized, chaotic changes in the electrical activity of the upper chambers of the heart, resulting in abnormal contractions.
a fast irregular rhythm in the atria
asynchronous contraction of the atria; results in the cessation of atrial pumping
atrial fibrillation: a common arrhythmia causing palpitations, exercise intolerance, and an increased risk of stroke.
A type of arrhythmia (irregular heartbeat) in which the atria (the upper two chambers of the heart) beat very rapidly, at up to 400 beats per minute and the ventricles respond by beating quickly and irregularly. Atrial fibrillation can produce quite unpleasant palpitations and sometimes breathlessness, and in some cases the fast irregular rhythm may lead to a clot forming in the heart.
Atrial fibrillation is an irregular heart rhythm in which many impulses begin andspread through the atria. The resulting rhythm is disorganized, rapid and irregularand the atria are not able to fully empty their contents into the ventricles.
An irregular heart rhythm which involves irregular and rapid beating in the upper chambers of the heart.
A heart disorder in which the upper left chamber of the heart (the atrium) beats out of rhythm.
rapid, irregular contractions of the heart muscle fibres
left atrium of heart ineffectively quivers instead of normally contracting.
An arrhythmia of the upper chamber of the heart (atrium). The uncoordinated beat cannot pass blood to the lower chamber (ventricle) of the heart effectively. The heart rhythm is irregular and sometimes fast. Atrial fibrillation is usually controlled with the medication Digitalis. If not controlled, it can lead to ineffective pumping action of the heart and, in rare instances, stroke.

The uncoordinated contractions or individual heart muscle fibers in the upper chambers of the heart. These chambers, called the atria, cannot contract in an organized fashion.
abnormal heart rhythm where the atria (upper chambers of the heart) quiver instead of beating normally.
An arrhythmia where the atria beat at a much higher than normal rate, with a very disorganized, chaotic pattern.
A condition where disorganized electrical conduction in the atrial walls results in ineffective pumping of blood into the ventricle and an irregular heart rhythm. Read more: Causes, symptoms, diagnosis, treatment.
More than 2 million people in the United States have atrial fibrillation, making it a very common heart rhythm disorder. In A Fib, the heartbeat is irregular and rapid, sometimes beating as often as 300 time a minute in the upper chambers (atria) and 100-150 times a minute in the lower chambers (ventricles). Although it isn't life threatening, A Fib can lead to other rhythm problems, chronic fatigue and congestive heart failure. Chances of having a stroke are five times higher for those with A Fib. There are a number of effective treatments to control AF and/or reduce the risk that it will cause serious health problems.
Rapid, irregular contractions of the atria followed by the irregular contractions of the ventricles.
A type of cardiac arrhythmia during which the atria (i.e. the top chambers of the heart) beat in an uncoordinated and disorganized fashion thus leading to a very irregular and fast rhythm.
When the atrium (the upper, low pressure chamber of the heart) does not squeeze or contract at one uniform, coordinated time but contracts irregularly with one portion contracting well before or after another, the result is what is called atrial fibrillation. When this happens the atrium cannot push blood into the ventricles in the normal manner.
Rapid, irregular contraction of the atria of the heart that produces an irregular and often rapid ventricular rate.
a rapid, irregular heart rhythm caused by abnormal electrical impulses that begin in the upper chambers of the heart. As a result, the heart's lower chambers beat rapidly and irregulary.
A very fast, disorganized heart rhythm that starts in the atria (upper chambers of the heart).
A common type of arrhythmia. It begins in the atria and may be transient or persistent. The heart rhythm is irregular.
a very fast and irregular beating of the atria (the upper two chambers of the heart).
A disorganized heart rhythm in the upper chambers of the heart (the atria).
A disorder that upsets the heart's rhythm, which may cause it to not pump enough blood to meet the body's needs.
Rapid, twitching contractions of one of the upper chambers or atrium of the heart.
An abnormal rhythm of the heart that can result in an increased risk of stroke due to the formation of emboli (blood clots) in the heart.
Heart condition in which the upper left side of the heart beats out of rhythm with the other three chambers. It increases the risk of a blood clot forming inside the heart, which can break off, travel to the brain and cause a TIA or stroke.
A condition in which the heartbeat is irregular and often unusually rapid.
A chaotic rhythm of the heart.... where the upper chamber of the heart quivers at rate of 600 times per minute or more. Only part of the contraction signals reach the lower chamber. Thus the actual rte of contraction in the lower pumping chambers is around 80 to 120/min. In AF, the patient feels an irregular heart beat (palpitations). If the rate goes too fast, medication need to be administered to slow the heart rate. Chronic AF can be associated with an increased risk of stroke so anticoagulation with Coumadin is recommnded.
Chaotic beating of the top chambers (atria) of the heart which can cause a rapid irregular pulse B C
Rapid, uneven contractions in the upper heart chambers (atria), which cause the lower chambers (ventricles) to beat irregularly.
Abnormal irregular heart rhythm with chaotic generation of electrical signals in the atria of the heart. Familiarly called atrial fib.
Extremely rapid, irregular atrial impulses that prevent the atria from effectively pumping blood into the ventricles. It can also cause irregular rapid ventricular beats.
Condition in which the two small upper chambers of the heart, the atria, quiver instead of beating effectively. Although atrial fibrillation is not in itself considered life-threatening, people with it are at an increased risk for blood clots and stroke. (Read about " Arrhythmia" " Stroke")
very rapid and irregular heartbeat; causes blood to not pump effectively into the ventricles (lower chambers).
an irregular heartbeat that causes a fluttering sensation of the heart.
an irregular heart rhythm that causes a fluttering sensation.
The most common form of irregular heartbeat (arrhythmia) and a risk factor for embolic ischemic stroke. The condition can cause a pooling of blood in the heart, which can make it easier for clots to form.
When a rapid and irregular rhythm begins in the upper chambers of the heart (the Atria), it is called Atrial fibrillation. As a result, the lower chambers also beat irregularly. There are health risks associated with this condition that require careful diagnosis and treatment.
An abnormal, irregular heart rhythm characterized by chaotic electrical signals emanating from the atria, the upper chambers of the heart. Also known as atrial fib or a-fib.
rapid, uneven contractions in atria, which causes a lack of synchronism between heartbeat and pulse beat .
Irregular pulse rate due to multiple chaotic impulses firing within the atrium and variably conducted or carried down through the AV node to the ventricles.
Extremely rapid, irregular atrial impulses. This rapid rate does not allow the atria to pump blood effectively into the ventricles. It can also cause irregular rapid ventricular beats.
rapid irregular twitchings of the heart chamber.
A type of arrhythmia in which the upper chambers of the heart (atria) have a completely disorganized rhythm, causing them to beat rapidly and ineffectively.
Irregular beating of the left atrium, or left upper chamber, of the heart.
(AF): A common type of irregular heartbeat, affecting about two million Americans. AF occurs when the upper two chambers of the heart, called the atria, quiver rather than contract normally. Back to Previous Page
An abnormal heart rhythm in which the heart's atria contract at an excessive and irregular rate.
An abnormal heart rhythm that may lead to poor circulation.
A disorder of the heart beat associated with a higher risk of stroke. In this disorder, the upper chambers (atria) of the heart do not completely empty when the heart beats, which can allow blood clots to form.
One type of fast and irregular heartbeat.
is a disorder of the heart's rhythm which makes the heart's upper chambers, called the atria, "twitch" instead of contract.
An irregular, rapid contraction of the atria (upper chambers of the heart).
rapid uncontrolled quivering of the upper chambers (atria) of the heart. The atria do not effectively pump blood.
Atrial arrhythmia is characterized rapid atrial rhythm due to multiple reentrant "wavelets" travelling throughout the atria, causing the upper chambers to contract in a chaotic manner (fibrillate). There are usually no P waves. Ventricular rhythm may be normal, although a wider QRS of the ventricular escape rhythm. Atrial fibrillation may occur in hypertensive diseases or pericarditis.
an irregular heartbeat in which the upper chambers of the heart (the atria) beat inconsistently and rapidly
Atrial fibrillation (AF or afib) is an abnormal heart rhythm (cardiac arrhythmia) which involves the two small, upper heart chambers (the atria). Heart beats in a normal heart begin after electricity generated in the atria by the sinoatrial node spreads through the heart and causes contraction of the heart muscle and pumping of blood. In AF, the regular electrical impulses of the sinoatrial node are replaced by disorganized, rapid electrical impulses which result in irregular heart beats.
