Definition

Atrial fibrillation (AF) is the most common sustained cardiac rhythm disturbance, affecting more than 2 million Americans, with an overall prevalence of 0.89%. The prevalence increases rapidly with age, to 2.3% between the ages of 40 and 60 years, and to 5.9% over the age of 65. The most dreaded complication is thromboembolic stroke (Brugada et al., 1997). For a discussion of genetic heterogeneity of atrial fibrillation, see 608583. [from OMIM]

Additional description

From MedlinePlus Genetics
Familial atrial fibrillation is an inherited abnormality of the heart's normal rhythm. Atrial fibrillation is characterized by episodes of uncoordinated electrical activity (fibrillation) in the heart's upper chambers (the atria), which cause a fast and irregular heartbeat. If untreated, this abnormal heart rhythm (arrhythmia) can lead to dizziness, chest pain, a sensation of fluttering or pounding in the chest (palpitations), shortness of breath, or fainting (syncope). Atrial fibrillation also increases the risk of stroke and sudden death. Complications of atrial fibrillation can occur at any age, although some people with this heart condition never experience any health problems associated with the disorder.  https://medlineplus.gov/genetics/condition/familial-atrial-fibrillation

Clinical features

From HPO
Sudden cardiac death
MedGen UID:
38841
•Concept ID:
C0085298
•
Pathologic Function
The heart suddenly and unexpectedly stops beating resulting in death within a short time period (generally within 1 h of symptom onset).

Atrial fibrillation
MedGen UID:
445
•Concept ID:
C0004238
•
Finding
An atrial arrhythmia characterized by disorganized atrial activity without discrete P waves on the surface EKG, but instead by an undulating baseline or more sharply circumscribed atrial deflections of varying amplitude an frequency ranging from 350 to 600 per minute.

Syncope
MedGen UID:
21443
•Concept ID:
C0039070
•
Sign or Symptom
Syncope is a syndrome in which loss of consciousness is of relatively sudden onset, temporary (usually less than 1 to 2 minutes), self-terminating, and of usually rapid recovery. Syncope leads to a generalized weakness of muscles with loss of postural tone, inability to stand upright, and loss of consciousness. Once the patient is in a horizontal position, blood flow to the brain is no longer hindered by gravitation and consciousness is regained. Unconsciousness usually lasts for seconds to minutes. Headache and drowsiness (which usually follow seizures) do not follow a syncopal attack. Syncope results from a sudden impairment of brain metabolism usually due to a reduction in cerebral blood flow.

Paroxysmal atrial fibrillation
MedGen UID:
115990
•Concept ID:
C0235480
•
Disease or Syndrome
Episodes of atrial fibrillation that typically last for several hours up to one day and terminate spontaneously.
See: Feature record | Search on this feature
Prolonged QTc interval
MedGen UID:
294666
•Concept ID:
C1560305
•
Pathologic Function
A longer than normal interval (corrected for heart rate) between the Q and T waves in the heart's cycle. Prolonged QTc can cause premature action potentials during late phase depolarizations thereby leading to ventricular arrhythmias and ventricular fibrillations.

Permanent atrial fibrillation
MedGen UID:
750308
•Concept ID:
C2586056
•
Pathologic Function
Atrial fibrillation (AF) that cannot be successfully terminated by cardioversion, and longstanding (more than 1 year) AF, where cardioversion is not indicated or has not been attempted, is termed permanent.

Thromboembolic stroke
MedGen UID:
488954
•Concept ID:
C1112433
•
Disease or Syndrome
A cerebrovascular accident (stroke) that occurs because of thromboembolism.
