Episodes can be asymptomatic. [3] Symptomatic episodes may involve heart palpitations, fainting, lightheadedness, loss of consciousness, shortness of breath, or chest pain. [2] Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14]
In the case of "holiday heart" Afib or even "weekend" Afib, it's tied to more alcoholic beverages being consumed, Natale said. How much alcohol triggers Afib is different in everybody, he said ...
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.
Fibrillation can affect the atrium (atrial fibrillation) or the ventricle (ventricular fibrillation): ventricular fibrillation is imminently life-threatening. Atrial fibrillation affects the upper chambers of the heart, known as the atria. Atrial fibrillation may be due to serious underlying medical conditions and should be evaluated by a ...
A normal resting heart rate is 60 to 100 beats per minute. A resting heart rate of more than 100 beats per minute is defined as a tachycardia. During an episode of SVT, the heart beats about 150 to 220 times per minute. [9] Specific treatment depends on the type of SVT [5] and can include medications, medical procedures, or surgery. [5]
Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. [2] It is due to disorganized electrical activity . [ 2 ] Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse . [ 1 ]
A rapid, irregular rhythm might be due to atrial fibrillation, atrial flutter, or tachycardia with a variable block. [1] Supraventricular and ventricular tachycardias often cause sudden palpitations, beginning and ending rapidly. If someone can stop their palpitations with the Valsalva maneuver, it may indicate SVT. [1]
Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
