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]
Anticoagulants: To prevent embolization.. Beta blockers: To block the effects of certain hormones on the heart to slow the heart rate.. Calcium Channel Blockers: Help slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles).
With Atrial fibrillation, or A-fib or AF, signals move around the atria in a completely disorganized way that tends to override the sinus node. Instead of a one big contraction then, you get all these mini contractions that make it just look like the atria are just quivering.
In 2011 an All-Party Parliamentary Group on atrial fibrillation (APGAF) was established in partnership with the AF Association. It is chaired by Glyn Davies MP, who is himself affected by AF. [10] The APGAF has published a number of reports on improving AF care in the NHS. [citation needed]
In October 2012, the Heart Rhythm Society launched a multi-year, national awareness campaign, "Arrest the Risk", in an effort to elevate the issue of preventing sudden cardiac arrest, early intervention, and appropriate treatment among the African-American and Hispanic populations; increase awareness of disparities at the point of care; and reduce mortality and re-hospitalization rates from ...
There are two major classes of cardiac fibrillation: atrial fibrillation and ventricular fibrillation. Atrial fibrillation is an irregular and uncoordinated contraction of the cardiac muscle of atria. It can be a chronic condition, usually treated with anticoagulation and sometimes with conversion to normal sinus rhythm.
It is also considered in patients with atrial fibrillation - a heart rhythm disorder characterised by irregular electrical impulses in the atria (the upper chambers of the heart). [88] This abnormal electrical activity causes the atria to contract erratically, resulting in an irregular heartbeat. [89]
Sanjiv M. Narayan is a British-born American physician, biomedical engineer, and academic researcher. He is a Professor of Medicine at Stanford University. [1] Narayan's work is focused on treating patients with heart rhythm disorders, particularly those with atrial fibrillation.
