What is the fibrillation?
1 : an act or process of forming fibers or fibrils. 2a : a muscular twitching involving individual muscle fibers acting without coordination. b : very rapid irregular contractions of the muscle fibers of the heart resulting in a lack of synchronism between heartbeat and pulse.
What is af Wiki?
Atrial fibrillation (AF or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by the rapid and irregular beating of the atrial chambers of the heart. It often begins as short periods of abnormal beating, which become longer or continuous over time.
What does fibrillation in EMG mean?
Fibrillation potentials are the most common abnormal spontaneous discharges recorded during needle EMG. Fibrillation potentials represent the action potentials of single muscle fibers that fire spontaneously in the absence of innervation (Buchthal and Rosenfalck, 1966; Goodgold and Eberstein, 1967).
What is fibrillation and types?
Types. Atrial fibrillation is a type of arrhythmia. There are four main types of atrial fibrillation—paroxysmal, persistent, long-term persistent, and permanent atrial fibrillation. The type of atrial fibrillation that you have depends on how often atrial fibrillation occurs and how it responds to treatment.

What is AF stroke?
What is AF-related stroke? The irregular rhythm of the heart caused by AF gives opportunity for the blood to pool and form into a clot. It is these clots that are at risk of breaking away and flowing through the blood until they cause a blockage and thus an ischaemic stroke (clot caused stroke).
What is the main cause of AFIB?
Abnormalities or damage to the heart’s structure are the most common cause of atrial fibrillation. Possible causes of atrial fibrillation include: High blood pressure. Heart attack.
Which type of fibrillation is the most serious?
Ventricular fibrillation is more serious than atrial fibrillation. Ventricular fibrillation frequently results in loss of consciousness and death, because ventricular arrhythmias are more likely to interrupt the pumping of blood, or undermine the heart’s ability to supply the body with oxygen-rich blood.
What do you need to know about defibrillation?
Defibrillation. Defibrillation is a treatment for life-threatening cardiac dysrhythmias, specifically ventricular fibrillation (VF) and non-perfusing ventricular tachycardia (VT). A defibrillator delivers a dose of electric current (often called a countershock) to the heart. Although not fully understood,…
How is a defibrillator used to treat VF?
Defibrillation is a treatment for life-threatening cardiac dysrhythmias, specifically ventricular fibrillation (VF) and non-perfusing ventricular tachycardia (VT). A defibrillator delivers a dose of electric current (often called a countershock) to the heart.
How is cardioversion used in cardiac defibrillation?
Cardioversion. Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle, restoring the activity of the electrical conduction system of the heart. ( Defibrillation uses a therapeutic dose of electric current to the heart at a random moment in the cardiac cycle,…
How is fibrillation used to stop the heart from beating?
Fibrillation may sometimes be used after heart surgery to stop the heart from beating while any minor leaks are stitched up. Fibrillation also occurs with individual skeletal muscle fibers.
