Researchers are working to determine which genetic changes may influence the risk of atrial fibrillation. [ citation needed ] Familial atrial fibrillation appears to be inherited in an autosomal dominant pattern, which means the defective gene is located on an autosome , and only one copy of the defective gene - inherited from one parent - is ...
Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]
It can have many potential causes, including genetics, lifestyle habits, and underlying health issues. Some types of cardiovascular disease, such as some cardiomyopathies, develop due to factors ...
Other, non-cardiovascular risk factors include obesity, diabetes, and excessive alcohol consumption. Adding to all this, there also seems to be a genetic component as well. These factors likely stress the cells in the atria, which can lead to tissue heterogeneity, which means that cells start taking on different electrical properties.
The consequence of fibrillation is that the chambers of the heart affected by the disorganised electrical activation lose their pumping ability – fibrillation of the cardiac atria in atrial fibrillation leads to an irregular pulse, and fibrillation of the cardiac ventricles in ventricular fibrillation renders the heart unable to pump blood at ...
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited genetic disorder that predisposes those affected to potentially life-threatening abnormal heart rhythms or arrhythmias. The arrhythmias seen in CPVT typically occur during exercise or at times of emotional stress, and classically take the form of bidirectional ...

It can result from an injury or be a genetically inherited disorder. [ 14 ] Atrioventricular nodal re-entry tachycardia , [ 11 ] which is caused by a dual AV node physiology and AVNRT can only occur in people with it, however almost half of the population have it, though only a few of them will develop AVNRT at some point in life.
