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]
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.
Those who have severe symptoms from an arrhythmia or are medically unstable may receive urgent treatment with a controlled electric shock in the form of cardioversion or defibrillation. [6] Arrhythmia affects millions of people. [4] In Europe and North America, as of 2014, atrial fibrillation affects about 2% to 3% of the population. [9]
The body has several feedback mechanisms to maintain adequate blood flow and blood pressure. If blood pressure decreases, the heart beats faster in an attempt to raise it. This is called reflex tachycardia. This can happen in response to a decrease in blood volume (through dehydration or bleeding), or an unexpected change in blood flow.
Thrombosis (from Ancient Greek θρόμβωσις (thrómbōsis) 'clotting') is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system. When a blood vessel (a vein or an artery ) is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss.
A complete blood count (CBC) can also be ordered to test for low platelets. [10] An EKG may be started to evaluate for abnormal heart rhythms, especially atrial fibrillation which often cause traditional emboli to form in the heart. Arterial blood gas measurements and metabolic panels may also be drawn for the purpose of supportive measures. [11]
NPPA variants affect plasma ANP concentrations, blood pressure levels, and cardiovascular diseases such as atrial fibrillation (AF). [11] ANP-deficient mice were found to have a large increase in heart and left ventricular weight in response to volume overload, which is normally prevented by proper regulation of blood pressure.
